Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

With the development of electronic equipment, full screen has become the development trend of mobile phones. The full screen and high screen-to-body ratio make the top of the screen have limited space for the proximity sensor or other components. When the proximity sensor is placed under the light-transmitting display, due to the photoelectric effect, the proximity sensor emits infrared light. The electrons in the light-transmitting display are excited to cause the light-transmitting display to flicker, which interferes with the normal display of the light-transmitting display and affects the user experience.

Referring to FIGS. 1-3 , an embodiment of the present invention provides an electronic device 100 . The electronic device 100 includes a touch screen 10 , a proximity sensor 16 , a temperature sensor 21 and a processor 23 . The touch display screen 10 includes a display layer 13 , and the display layer 13 includes a display area 1311 . The proximity sensor 16 is disposed below the touch display screen 10 . Further, the proximity sensor 16 is disposed below the display area 1311 . The proximity sensor 16 is used to emit infrared light and receive the infrared light reflected by the object to detect the distance from the object to the electronic device 100 .

Exemplarily, the electronic device 100 may be any one of various types of computer system devices that are mobile or portable and perform wireless communication (only one form is shown in FIG. 1 exemplarily). Specifically, the electronic device 100 can be a mobile phone or a smart phone (for example, based on iPhone TM, a phone based on Android TM), a portable game device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop Computers, PDAs, portable Internet devices, music players and data storage devices, other handheld devices and such as watches, earphones, pendants, headphones, etc., the electronic device 100 can also be other wearable devices (for example, Head-mounted devices (HMD) such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices or smart watches).

Electronic apparatus 100 may also be any of a number of electronic devices including, but not limited to, cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders , video recorders, cameras, other media recorders, radios, medical equipment, vehicle transport equipment, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable Multimedia players (PMP), Moving Picture Experts Group (MPEG-1 or MPEG-2) audio layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

In some cases, the electronic device 100 may perform various functions (eg, play music, display video, store pictures, and receive and send phone calls). If desired, electronic device 1000 may be a portable device such as a cellular phone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

The mobile phone is provided with the proximity sensor 16 to determine the distance between the mobile phone and the obstacle and make corresponding adjustments, which can prevent misoperation of the user and help save the power of the mobile phone. For example, when the user is answering or making a call and brings the mobile phone close to the head, the proximity sensor 16 generates detection information by calculating the time when the emitter emits infrared light and the receiver receives the reflected infrared light, and the processor 23 touches the Display10. When the mobile phone is far away from the head, the processor 23 turns on the touch display screen 10 again according to the detection information fed back by the proximity sensor 16 .

In some embodiments, the display layer 13 includes an OLED display layer.

Specifically, the OLED display layer has good light transmittance, and can better transmit visible light and infrared light. Therefore, the OLED display layer can display content effects without affecting the proximity sensor 16 to emit and receive infrared light. The display layer 13 can also be a Micro LED display layer, and the Micro LED display layer also has good light transmittance to visible light and infrared light. Of course, these display layers are only exemplary and the embodiments of the present invention are not limited thereto. In addition, the touch display screen 10 may be disposed on the casing 20 .

Please refer to FIG. 3 , in some embodiments, the touch display screen 10 further includes a transparent cover 11 and a touch layer 12 . The transparent cover 11 is disposed on the touch layer 12 . The touch layer 12 is disposed on the display layer 13 . The upper surface 131 of the display layer 13 faces the touch layer 12 . Both the visible light transmittance and the infrared light transmittance of the transparent cover plate 11 and the touch layer 12 are greater than 90%.

Specifically, the touch layer 12 is mainly used to receive user input signals and transmit them to the circuit board for data processing, so as to obtain the specific position where the user touches the touch layer 12 . It should be pointed out that, the touch layer 12 being disposed on the display layer 13 may mean that the touch layer 12 is in contact with the display layer 13 . For example, In-Cell or On-Cell technology can be used to bond the touch layer 12 and the display layer 13 , which can effectively reduce the weight of the display layer 13 and reduce the overall thickness of the display layer 13 . The touch layer 12 disposed on the display layer 13 may also mean that the touch layer 12 is disposed above the display layer 13 and spaced from the display layer 13 .

In addition, disposing the light-transmitting cover plate 11 on the touch layer 12 can effectively protect the touch layer 12 and its internal structure, and avoid damage to the touch layer 12 and the display layer 13 by external forces. The light transmittance of the light-transmitting cover plate 11 and the touch layer 12 to visible light and infrared light is greater than 90%, which not only helps the display layer 13 to better display the content effect, but also facilitates the proximity sensor arranged under the display layer 13. 16 emits and receives infrared light stably, which ensures the normal operation of the proximity sensor 16 .

Referring to FIG. 4 , in some embodiments, the display layer 13 includes an upper surface 131 and a lower surface 132 . The electronic device 100 further includes a first coating layer 14 coated on the lower surface 132 and covering the proximity sensor 16 . The first coating layer 14 is used to transmit infrared light and block visible light. The proximity sensor 16 is used to transmit and/or receive infrared light through the first coating layer 14 and the display layer 13 .

Specifically, setting the first coating layer 14 to transmit infrared light is to ensure the normal operation of the proximity sensor 16 . The first coating layer 14 intercepts visible light so that the proximity sensor 16 cannot be seen when the electronic device 100 is viewed from the outside.

Referring to FIG. 4 and FIG. 5 , in some embodiments, the proximity sensor 16 includes a transmitter 1611 and a receiver 1612 . The emitter 1611 is used for emitting infrared light through the first coating layer 14 and the display layer 13 . The receiver 1612 is used for receiving the infrared light emitted by the object to detect the distance between the object and the electronic device 100 .

Specifically, generally, when the user is answering or making a call, the electronic device 100 is close to the head of the human body, the emitter 1611 emits infrared light, and the receiver 1612 receives the reflected infrared light. The processor 23 calculates the time from when the infrared light is emitted to when it is reflected back, and sends a corresponding instruction to control the screen to be turned off. When the electronic device 100 is far away from the head, the processor 23 performs calculations again according to the fed back data and issues an instruction to turn on the screen again. In this way, not only the misoperation of the user is prevented, but also the power of the mobile phone is saved.

In some embodiments, the orthographic projection of the proximity sensor 16 on the lower surface 132 is within the orthographic projection of the first coating layer 14 on the lower surface 132 .

Specifically, during the assembly process, the installation of the proximity sensor 16 usually requires an assembly gap to be reserved, resulting in a gap between the proximity sensor 16 and other components, allowing visible light to enter through the gap, resulting in light leakage. Therefore, in the direction in which the proximity sensor 16 and the display layer 13 are stacked, the area of the orthographic projection of the first coating layer 14 on the lower surface 132 is greater than the area of the orthographic projection of the proximity sensor 16 on the lower surface 132, which can be achieved without affecting the normal operation of the proximity sensor 16. When working, the first coating layer 14 is made to fully cover the proximity sensor 16 , so that the proximity sensor 16 is invisible when the electronic device 100 is viewed from the outside.

Referring to FIG. 5 , in some embodiments, the orthographic projection of the proximity sensor 16 on the lower surface 132 coincides with the first coating layer 14 .

Specifically, in the stacking direction of the proximity sensor 16 and the display layer 13 , the area of the first coating layer 14 orthographically projected on the lower surface 132 may be equal to the area of the proximity sensor 16 on the lower surface 132 . In this way, without affecting the normal operation of the proximity sensor 16, the first coating layer 14 can just cover the proximity sensor 16, so that when the electronic device 100 is viewed from a direction facing and perpendicular to the upper surface 131 of the display layer 13, the proximity sensor 100 can be reached. The sensor 16 is not visible to the effect.

Please refer to FIG. 6 , further, in such an embodiment, the electronic device 100 further includes a light shielding layer 17 disposed on the lower surface 132 and surrounding the proximity sensor 16 .

Specifically, when the area of the front projection of the first coating layer 14 on the lower surface 132 is equal to the area of the proximity sensor 16 on the lower surface 132, since the volume of the space where the proximity sensor 16 is placed is greater than the volume of the proximity sensor 16 Large, resulting in light leakage in the space around the proximity sensor 16 when the electronic device 100 is viewed from the external environment. Therefore, by setting the light-shielding layer 17 surrounding the proximity sensor 16 to fill the gap between the proximity sensor 16 and the surrounding space, this light leakage phenomenon can be eliminated. The light-shielding layer 17 can be foam made of black material, or other black foam plastics or rubber. Of course, these materials are only exemplary and the embodiments of the present invention are not limited thereto.

In some embodiments, the first coating layer includes IR ink, the transmittance of IR ink to infrared light is greater than 85%, the transmittance of IR ink to visible light is less than 6%, and the transmittance of IR ink to infrared light is less than 6%. The wavelength is 850nm-940nm.

Specifically, since the IR ink has low transmittance to visible light, when the electronic device 100 is viewed from the outside, the proximity sensor 16 disposed under the first coating layer 14 cannot be observed based on human vision. At the same time, the IR ink has the characteristics of high transmittance to infrared light, which enables the proximity sensor 16 to emit and receive infrared light stably, and ensures the normal operation of the proximity sensor 16 .

Referring to FIGS. 7 and 8 , in some embodiments, the electronic device 100 further includes a second coating layer 15 coated on the lower surface 132 and in contact with the first coating layer 14 .

Specifically, the first coating layer 14 is mainly used to transmit infrared light and block the proximity sensor 16, but because the cost of the IR ink used in the first coating layer 14 is higher than that of ordinary black ink, if the lower surface 132 is completely coated IR ink will not be conducive to reducing production costs, and the light transmittance of ordinary black ink to visible light can be lower than that of IR ink, and the blocking effect is more prominent. In this way, by providing the second coating layer 15, not only is it beneficial to reduce the production cost, but also the shielding effect is more in line with the technical requirements.

Referring to FIGS. 9 and 10 , in some embodiments, the electronic device 100 further includes a buffer layer 18 covering the lower surface 132 and avoiding the proximity sensor 16 .

Specifically, the buffer layer 18 is used to reduce shock force and shockproof to protect the touch layer 12, the display layer 13 and their internal structures, and prevent the display layer 13 from being damaged by external impact. The buffer layer 18 can be made of foam or foam plastic or rubber or other soft materials. Of course, these cushioning materials are only exemplary and the embodiments of the present invention are not limited thereto. In addition, avoiding the proximity sensor 16 during the process of setting the buffer layer 18 is to prevent the buffer layer 18 from covering the proximity sensor 16, so as to prevent the proximity sensor 16 from being affected during the process of emitting and receiving infrared light.

Please refer to FIG. 11 and FIG. 12 , further, in such an embodiment, the electronic device 100 further includes a metal sheet 19 covering the buffer layer 18 and avoiding the proximity sensor 16 .

Specifically, the metal sheet 19 is used for shielding electromagnetic interference and grounding, and has the effect of diffusing temperature rise. The metal sheet 19 can be cut from metal materials such as copper foil and aluminum foil. Of course, these metal materials are only exemplary and the embodiments of the present invention are not limited thereto. In addition, avoiding the proximity sensor 16 during the process of setting the metal sheet 19 is to prevent the metal sheet 19 from covering the proximity sensor 16, so as to prevent the proximity sensor 16 from being affected during the process of emitting and receiving infrared light.

Please refer to FIGS. 13-15 together. In some embodiments, the electronic device 100 further includes a housing 20 , a housing case 200 , a light guide 51 and a light sensor 5 . The housing 200 is slidably connected to the housing 20 and can extend out of the housing 20 or retract into the housing 20 . The receiving case 200 is provided with a light incident hole 2006 , and the light guide element 51 is accommodated inside the receiving case 200 and partially extends into the light entering hole 2006 . The light guide 51 has a light incident surface 511 and a light exit surface 512 opposite to each other. The light incident surface 511 faces the outside of the housing 200 . The light emitting surface 512 faces the inside of the housing 200 . The light sensor 5 is accommodated inside the housing 200 and faces the light emitting surface 512 .

In this way, since the light incident hole 2006 is disposed in the housing 200 of the electronic device 100 instead of the touch screen 10 of the electronic device 100, the setting of the light incident hole 2006 can meet the requirements of the light sensor 5 to receive ambient light. , the screen-to-body ratio of the touch display screen 10 will not be limited, so that the screen-to-body ratio of the electronic device 100 is relatively large.

Specifically, referring to FIGS. 13-14 , the electronic device 100 is defined with reference to this viewing angle. The electronic device 100 has a width direction X, a length direction Y, and a thickness direction Z. The length direction Y is perpendicular to the width direction X, and the thickness direction Z It is perpendicular to the width direction X and the length direction Y.

The housing 20 also includes a top end surface 1002 and a bottom end surface 1003 opposite to the top end surface 1002 . Generally, the top end surface 1002 and the bottom end surface 1003 can extend along the width direction X. That is, the top end surface 1002 and the bottom end surface 1003 are short sides of the electronic device 100 . The bottom surface 1003 is used for arranging connectors, microphones, speakers, etc. of the electronic device 100 .

As shown in FIG. 14 , a receiving groove 1004 is opened on the top of the housing 20 , and the receiving groove 1004 is recessed from the top of the housing 20 to the inside of the housing 20 . The receiving groove 1004 runs through the side of the casing 20 . The receiving case 200 is slidably connected with the casing 20 in the receiving groove 1004 . In other words, the receiving shell 200 is slidably connected to the housing 20 to extend or retract the receiving slot 1004 .

A functional element 300 can also be set in the housing 200. The functional element 300 is, for example, a camera, an earpiece, or a laser transmitter. The camera is exposed through the light entrance hole 2006. When the housing 200 extends out of the housing 20 , the camera can capture external images of the electronic device 100 . The camera is, for example, a camera such as an RGB camera.

In some embodiments, the housing case 200 has an outer surface, and part or all of the light incident surface 511 protrudes relative to the outer surface. In this way, the housing case 200 less blocks the light incident surface 511, or even does not block the light incident surface 511 at all, so that the light incident surface 511 can receive more ambient light, and the light guide 5151 can better guide the external light into the light sensor. sensor 5.

In this embodiment, the outer surface of the housing 200 includes a top surface 2003 , and the top surface 2003 defines a light incident hole 2006 . The light guide 51 corresponds to the light incident hole 2006 on the top surface 2003 . In other words, the light sensor 5 receives the light passing through the light incident hole 2006 on the top surface 2003 through the light guide 51 . In this way, no matter whether the housing 200 is extended or retracted to the housing 20 , the light sensor 5 can sense ambient light. Part or all of the light incident surface 511 protrudes relative to the top surface 2003 .

Referring to FIGS. 15-17 , the light incident surface 511 has a central area 5111 and an edge area 5112 surrounding the central area 5111 . The central area 5111 protrudes relative to the edge area 5112 . At this time, the area of the light incident surface 511 is larger, and more external light can enter the light guide 51 . Wherein, the light incident surface 511 is an arc surface.

In some embodiments, the housing 200 has an inner surface 2063, and the inner surface 2063 forms a positioning groove 2064, and the positioning groove 2064 communicates with the light entrance hole 2006. The light guide 51 includes a light entrance portion 513 and a light exit portion 514, and the light entrance surface 511 The light incident part 513 is the end surface away from the light exit part 514, and the light exit surface 512 is the end surface of the light exit part 514 facing away from the light entrance part 513. The light incident part 513 penetrates the light entrance hole 2006, and the light exit part 514 is partially or completely embedded in the positioning groove 2064.

At this time, the light guide member 5151 and the housing case 200 are fixed to each other and are not easy to slide. At the same time, the surface of the light exit portion 514 facing the light entry portion 513513 can be bonded with a sealing member, and the sealing member is continuously arranged around the light entry portion 513513 . The seal is held against the light exit portion 514 and the groove wall of the positioning groove 2064 to achieve sealing and prevent external dust, water vapor, etc. from entering the interior of the housing 200 through the light entrance hole 2006 .

In some embodiments, the area of the light exit surface 512 is larger than the area of the light entrance surface 511 , and the cross-sectional area of the light entrance portion 513 increases gradually in the direction from the light entrance surface 511 to the light exit surface 512 .

Specifically, the shape of the light incident portion 513 is approximately a truncated cone, which facilitates the transmission of light in the light incident portion 3513 and can be diffused to uniformly enter the light exit portion 514 .

In some embodiments, the light guiding element 51 further includes a positioning portion 515 , and the positioning portion 515 and the light emitting portion 514 define an accommodating space 516 for accommodating the light sensor 5 . The light sensor 5 accommodated in the accommodating space 516 can be protected by the positioning portion 515 and the light emitting portion 514 to avoid damage when the electronic device 100 is dropped or impacted. Wherein, a gap is formed between the light emitting surface 512 and the photosensitive area 52 of the photosensor 5 .

Please refer to FIG. 18 , the present invention provides a method for controlling an electronic device 100 . The control method includes the steps of:

S10, when the electronic device 100 is in a call service, collect an output signal of the touch screen 10;

S11, when the output signal changes, judge whether the change trend of the output signal conforms to the predetermined trend; and

S12, if the change trend conforms to the predetermined trend, control the display state of the touch screen according to the output signal.

In some embodiments, the processor 23 is used to collect the output signal of the touch display screen 10 when the electronic device 100 is in a call service, and determine whether the change trend of the output signal conforms to a predetermined trend when the output signal changes, and then When the trend conforms to the predetermined trend, the display state of the touch screen is controlled according to the output signal.

Referring to FIG. 19 , the embodiment of the present invention also provides a control device 2000 of the electronic device 100 , the control method of the electronic device 100 in the embodiment of the present invention can be realized by the control device 2000 of the electronic device 100 in the embodiment of the present invention.

Specifically, the control device 2000 includes a collection module 210 , a processing module 220 and a control module 230 . The collecting module 210 is used for collecting the output signal of the touch screen 10 when the electronic device 100 is in a call service. The processing module 220 is used for judging whether the change trend of the output signal conforms to a predetermined trend when the output signal changes. The control module 230 is used for controlling the display state of the touch screen according to the output signal when the change trend conforms to the predetermined trend.

That is to say, step S10 can be implemented by the collection module 210 . Step S11 can be implemented by the processing module 220 , and step S12 can be implemented by the control module 230 .

In the control method, the control device 2000 and the electronic device 100 of the embodiments of the present application, when the proximity detection is performed through the touch screen, it is judged whether the change of the output signal conforms to the predetermined trend, thereby eliminating the interference of other factors on the proximity detection, so that the touch display The proximity detection of the screen 10 is more accurate.

Specifically, the touch screen 10 is, for example, a capacitive touch screen. The touch screen 10 can output different capacitance values according to the distance between the object and the touch screen 10. Whether the display screen 10 is blocked can be touched. For example, the number of capacitance values output by the touch screen 10 is 10, and it is determined that the touch screen 10 is blocked when the 10 capacitance values are all larger than the threshold and basically consistent.

In one example, when the electronic device 100 enters the call service, the user generally puts the electronic device 100 to the ear. During the process of the user putting the electronic device 100 to the ear, since the parts with skin such as the face and ears are Conductor, the touch screen 10 can generate different signal values according to the distance between the electronic device 100 and the human head, thereby judging whether the user has completed the action of putting the electronic device 100 to the ear, thereby controlling whether the proximity sensor 16 is turned on.

The touch display screen supporting floating touch includes two kinds of capacitance signals, mutual capacitance signal and self capacitance signal. The self-capacitance signal is stronger than the mutual-capacitance signal, and can detect farther finger sensing, and the detection distance range can reach 20mm. The electric field of the mutual capacitance signal is so small that the signal strength is very low, and those very weak signals cannot be sensed. Therefore, when the user's finger hovers over the screen, the hovering of the finger cannot be detected according to the mutual capacitance signal.

In this embodiment, when the touch display screen 10 performs proximity detection, it judges whether there is an object approaching the touch display screen 10 according to the self-capacitance signal. Touch operation, and when the touch screen is in the touch detection state, it can be judged whether there is a touch operation according to the mutual capacitance signal.

When an approaching action occurs, the output signal of the touch screen 10 shows a trend of continuous change as the external object gradually approaches the touch screen 10. Since the self-capacitance signal is susceptible to external environmental factors, such as brightness, temperature, etc. In the actual operation process, the self-capacitance signal may change suddenly due to changes in temperature or brightness, so that it no longer has a continuous change trend. In this case, it may lead to misjudgment of proximity detection, so that the current proximity action cannot be accurately judged. .

When leaving the factory, the electronic device 100 can store a data model of proximity detection, that is, when the human ear or face approaches the touch display 10, the data of the self-capacitance signal change of the touch display 10, in actual operation, the processor 23. By comparing the change of the obtained self-capacitance data with the data model, it is judged whether to trigger the proximity operation. It should be noted that, in the embodiment of the present application, the touch display screen 10 can only be used to detect the approaching action, but cannot detect the moving away action. Understandably, when it is determined that the approaching action is triggered, the touch display screen 10 will go out and Electric signals are no longer generated, and at this time, the proximity sensor 16 is turned on, and it is judged whether the distance action is triggered by the proximity sensor 16 . In the embodiment of the present application, the proximity sensor 16 is disposed below the touch display screen 10 .

In this implementation manner, the call service includes incoming calls, outgoing calls or connected calls. Furthermore, the call service can be the process in which the user conducts a voice conversation, for example, the call service is the process in which the user dials out a call to another person and waits for the other party to answer, that is, the outgoing call state; it can also be the process in which the user is talking to another person through voice, That is, the call-connected state; it may also be a process in which the electronic device 100 connects to an external incoming call and waits for the user to answer it, that is, the incoming call state.

The change trend refers to that when the detected self-capacitance signal starts to change, it is considered that there is an approaching action. As the external object continues to approach the touch screen 10, the value of the self-capacitance signal will continue to change and gradually decrease. A trend is also a predetermined trend.

In actual operation, when it is detected that the self-capacitance signal changes and coincides with the occurrence of an approach action, it is detected whether the subsequent change trend of the self-capacitance signal conforms to the predetermined trend of the change of the self-capacitance signal when the approach action occurs. When the change trend conforms to the predetermined trend, it is considered that there is no external factor interference, or that the external factor will not affect the proximity detection.

When changes conform to predetermined trends, control methods include:

Judging whether the touch display screen 10 is blocked according to the output signal; and

When the touch display screen 10 is blocked, the touch display screen 10 is controlled to enter the extinguished state.

Specifically, the display state of the touch display screen 10 can be controlled according to the output signal of the touch display screen 10, so that the electronic device 100 controls the touch display screen 10 to enter the extinguished state when the electronic device 100 is talking and the touch display screen 10 is blocked to save power. .

The off state of the touch display screen 10 includes that the display area 1311 is completely off; or a part of the display area 1311 displays predetermined content while other parts of the display area 1311 are in an off state. When the display area 1311 is completely off, the touch display screen 10 is powered off, and the display area 1311 presents a black appearance.

A part of the display area 1311 displays predetermined content while other parts of the display area 1311 are off. It means that only a part of the display area 1311 is on and displays predetermined content, while other parts of the display area 1311 are off.

For example, when only a part of the display area 1311 is on and displaying predetermined content, the touch display screen 10 is in an off-screen AOD (Always on Display) mode. The predetermined content is, for example, time. That is to say, the display area 1311 can display time information no matter whether the touch display screen 10 enters a sleep state or wakes up state. Certainly, the predetermined content may also be content such as date, signal strength of the electronic device 100 , and the like.

In contrast, the on state of the touch display screen 10 refers to that the touch display screen 10 is powered on, and all areas of the display area 1311 are lit so that the display area 1311 can display content.

Preferably, the control method further includes detecting whether the posture of the electronic device 100 is a predetermined posture.

In this step, the posture of the electronic device 100 may be detected by a sensor such as a gyroscope of the electronic device 100 .

In this way, the process of controlling the display state of the touch screen 10 is more precise. It can be understood that, in some scenarios, even if the electronic device 100 enters the call service, it is not necessarily determined that the user has completed the action of putting the electronic device 100 to the ear according to the signal output by the touch screen 10 . For example, after the electronic device 100 enters the call service, the user's finger touches the touch screen 10. During this process, the electronic device 100 is not placed next to the user's ear, but the touch screen 10 will also output different capacitance signals. .

By judging the posture of the electronic device 100 , it can be further determined whether the electronic device 100 is placed near the user's ear. Specifically, the attitude of the electronic device 100 may be determined by using sensors such as a gyroscope and a gravity sensor. In addition, there are many postures of the electronic device 100, such as laying flat, upside down, and vertically. Since the user generally raises his hand to place the electronic device 100 vertically next to the user's ear when making a call, , the predetermined posture may be set as the vertical posture of the electronic device 100 after the user raises his hand. It can be understood that the process of the user raising his hand may be detected by sensors such as a gyroscope and a gravity sensor of the electronic device 100 .

For example, when the attitude of the electronic device 100 is detected by the gravity sensor, the gravity sensor can detect acceleration changes in three directions of the electronic device 100 in the width direction X, the length direction Y and the thickness direction Z. The gravity sensor continuously acquires data in the X direction, Y direction and Z direction of the electronic device 100 . It can be understood that when the electronic device 100 is placed near the ear and is in the process of talking, the distance that the electronic device 100 moves in the X direction and the Y direction is relatively small. Therefore, the gravity sensor detects that the amount of data change in the X direction and the Y direction is small.

If the electronic device 100 is brought from the ear to the front, then the electronic device 100 moves farther in at least two of the three directions X, Y, and Z. Therefore, the gravity sensor acquires The amount of data change in at least two directions of the Y direction and the Z direction is relatively large.

Thus, the attitude of the electronic device 100 can be obtained according to the amount of data change in the X direction, the Y direction, and the Z direction acquired by the gravity sensor.

As another example, when the attitude of the electronic device 100 is detected by the gyroscope, the gyroscope measures the rotational angular velocity when the electronic device 100 is tilted and tilted. Gyroscopes detect and sense linearity and motion in 3D space, allowing them to recognize orientation, determine attitude, and calculate angular velocity. In this way, according to the detection data of the gyroscope, it can be determined whether the posture of the electronic device 100 is an upright posture, a flat posture, or an oblique posture.

As mentioned above, the distance between the touch screen 10 and the object can be judged according to the different capacitance values output by the touch screen 10 and the number of capacitance values.

Preferably, in some embodiments, the control method includes:

Whether the touch display screen 10 is blocked is judged according to the control signal output from the top area of the touch display screen 10 .

Since the receiver of the electronic device 100 is usually disposed on the top of the electronic device 100 . In one example, when the user answers the phone, the top of the electronic device 100 is closer to the ear, therefore, judging whether the touch display 10 is covered according to the signal output from the top area of the touch display 10 can improve the judgment of the electronic device 100 approaching the head. part accuracy.

In this embodiment, the top area of the touch display screen 10 refers to the area of the touch display screen 10 close to the top surface 1002 of the electronic device 100 in the Y direction.

Referring to Figure 20, in some embodiments, the control method includes:

S13: When the change trend does not conform to the predetermined trend, determine whether a predetermined change occurs in the brightness of the touch screen.

In such an embodiment, S13 includes:

S131: judging whether the brightness change exceeds a predetermined brightness threshold;

S132: When the change in brightness is less than or equal to the predetermined brightness threshold, determine that a predetermined change in brightness occurs; and

S133: When the change in brightness is greater than the predetermined brightness threshold, determine that an unscheduled change in brightness occurs.

In some implementations, step S13 may be implemented by the processing module 220, or in other words, the processing module 220 is configured to determine whether the brightness of the touch screen 10 has a predetermined change when the change trend does not conform to the predetermined trend.

In some implementations, the processor 23 is configured to determine whether the brightness of the touch screen 10 has a predetermined change when the change trend does not conform to the predetermined trend.

In such an embodiment, steps S131-S133 may be implemented by the processing module 220, or in other words, the processing module 220 is used to determine whether the change in brightness exceeds a predetermined brightness threshold, and determine the brightness when the change in brightness is less than or equal to the predetermined brightness threshold. A predetermined change occurs, and when the change in brightness is greater than a predetermined brightness threshold, it is determined that an unscheduled change in brightness occurs.

In such an embodiment, the processor 23 is configured to determine whether the brightness change exceeds a predetermined brightness threshold, and when the brightness change is less than or equal to the brightness predetermined threshold, determine that the brightness has a predetermined change, and when the brightness change is greater than the brightness predetermined threshold, determine Unintended changes in brightness.

Specifically, the brightness change includes changing from dark to bright and from bright to dark. For example, the use environment of the electronic device 100 changes greatly, from a darker place to a brighter place. When the electronic device 100 adopts automatic brightness setting, it also That is, the brightness of the touch display screen 10 changes automatically with the change of the ambient brightness. Under such a setting, when the use environment of the electronic device 100 changes from bright to dark or changes from dark to dark, the brightness of the touch screen 10 will be larger. Variety. The greater the brightness of the touch screen 10 , the greater the capacitance of the touch screen 10 , and the greater the change of the brightness from low to high, the greater the change of the capacitance of the touch screen 10 . At this time, due to the large change in the brightness of the touch screen 10, the capacitance value output by each part of the touch screen 10 changes abruptly, so that the output signal of the touch screen 10 cannot accurately indicate whether the touch screen 10 is shaded. Cause false triggering of the state of touching the display screen 10 .

Therefore, it is necessary to determine whether a predetermined change occurs by detecting the brightness change degree of the touch display screen 10. When a predetermined change occurs, the change of the capacitance value of the touch display screen 10 is considered to be highly reliable, that is, it can be Proximity detection is performed by using the change of the capacitance value, and when there is no predetermined change, it is considered that the influence of the brightness change on the capacitance value is relatively large, and it is not suitable to use the touch screen 10 for proximity detection.

The brightness change refers to the change in the brightness of the backlight of the touch screen 10 at the current moment after the electronic device 100 enters the call service compared to the first moment before the current moment after entering the call service. For example, the display brightness may generally include There are 1024 levels, that is, there are 1024 levels from the lowest brightness to the highest brightness. In this embodiment, the brightness change threshold is set to 200, that is to say, the brightness of the touch screen 10 changes more than two times before and after. 200, the change in brightness does not change as expected. At this time, the change in brightness will greatly affect the capacitance value of the touch screen 10, and it is not suitable to use the touch screen 10 for proximity detection.

And if the change in brightness is less than 200, it is considered that the change in brightness of the touch screen 10 is a predetermined change.

It should be noted that the predetermined threshold in the step is only for illustrative illustration, and should be specifically set according to the relationship between brightness change and capacitance value change, and is not limited here.

Referring to Figure 21, in some embodiments, the control method includes:

S14: When the change trend does not conform to the predetermined trend, determine whether an area of the touch display screen is covered by liquid.

In such an embodiment, S14 includes:

S141: Detecting whether the position of the changed capacitance value forms a predetermined shape according to the output signal;

S142: If the positions of the changed capacitance values are continuous and form a predetermined shape, determine that an area of the touch display screen is covered by liquid; and

S143: If the position of the changed capacitance value does not form a predetermined shape, determine that the touch screen is not covered by liquid.

In some implementations, step S14 may be implemented by the processing module 220, or in other words, the processing module 220 is configured to determine whether an area of the touch screen is covered by liquid when the change trend does not conform to the predetermined trend.

In some implementations, the processor 23 is configured to determine whether an area of the touch display screen 10 is covered by liquid when the change trend does not conform to the predetermined trend.

In such an embodiment, steps S141-S143 can be implemented by the processing module 220, or in other words, the processing module 220 is used to detect whether the position of the changed capacitance value forms a predetermined shape according to the output signal, and If the position is continuous and forms a predetermined shape, it is determined that an area of the touch display screen is covered by liquid, and if the predetermined shape is not formed at the position where the capacitance value changes, it is determined that the touch display screen is not covered by liquid.

In such an embodiment, the processor 23 is used to detect whether the position of the changed capacitance value forms a predetermined shape according to the output signal, and continue to form a predetermined shape at the position of the changed capacitance value, and determine that an area of the touch display screen is blocked. Liquid coverage, and no predetermined shape is formed at the location of the changed capacitance value, it is determined that the touch display screen is not covered by liquid.

Specifically, the liquid includes sweat or water droplets attached to the touch display screen 10 during use, for example, when the user answered the phone last time, the sweat on the face adhered to the touch display screen 10, or the user cleaned the touch screen 10. Water droplets attached to the touch display screen 10 from the back of the hand, or other splashed liquids adhere to the touch display screen 10 . It can be understood that when a liquid drop splashes and covers a part of the touch screen 10, the capacitance value of this area will change, but at this time there is no real approach action. If the processor 23 outputs The signal to control the display state may cause the touch display screen 10 to be extinguished by mistake.

Therefore, it is necessary to judge the credibility of the output signal by judging whether there is an area covered by liquid on the touch screen 10. When it is not covered by liquid, the change of the capacitance value of the touch screen 10 is considered to be highly reliable. That is, the change of capacitance value can be used for proximity detection, but when there is an area covered by liquid on the touch screen 10, it is considered that the reliability of the change of capacitance value in the corresponding area is poor, and it is not suitable to use the touch screen 10 for detection. proximity detection.

When a droplet of liquid splashes onto the touch screen 10, a diffused continuous area is formed, such as the shape of a water droplet spreading, and the capacitance value at the corresponding position of the touch screen 10 changes, that is to say, the capacitance value changes The contacts form a shape similar to the spread of liquid stains, that is, the changing capacitance value is continuous and has a certain regionality. The predetermined shape mentioned above should be understood in a broad sense, not to limit a fixed shape, but to have a continuous and regionally changing formation should be understood as a predetermined shape. At this time, the reliability of the output signal of the touch screen 10 is low, and it is not suitable to use the touch screen 10 as the approach detection. Conversely, when the touch point where the capacitance value changes is discrete, discontinuous, or not in the form of liquid diffusion, it can be considered that the position where the capacitance value changes does not form a predetermined shape, and at this time it can be considered that the touch screen 10 Not covered by liquid.

Referring to Figure 22, in some embodiments, the control method includes:

S15: When the change trend does not conform to the predetermined trend, determine whether the display screen of the electronic device has a predetermined change.

In such an embodiment, S15 includes:

S151: Determine whether the number of pixel changes corresponding to the display screen exceeds a predetermined threshold;

S152: When the number of pixel changes is less than or equal to a predetermined threshold, determine that a predetermined change occurs in the display screen; and

S153: When the number of pixel changes is greater than a predetermined threshold, determine that an unscheduled change occurs in the display screen.

In some implementations, step S15 may be implemented by the processing module 220, or in other words, the processing module 220 is configured to determine whether a predetermined change occurs in the display screen of the electronic device when the change trend does not conform to the predetermined trend.

In some implementations, the processor 23 is configured to determine whether a predetermined change occurs in the display screen of the electronic device when the change trend does not conform to the predetermined trend.

In such an embodiment, steps S151-S153 may be implemented by the processing module 220, or in other words, the processing module 220 is used to determine whether the number of pixel changes corresponding to the display screen exceeds a predetermined threshold value, and when the number of pixel changes is less than or equal to the predetermined threshold value , it is determined that a predetermined change occurs in the display screen, and when the number of pixel changes is greater than a predetermined threshold value, it is determined that an unscheduled change occurs in the display screen.

In such an embodiment, the processor 23 is used to determine whether the number of pixel changes corresponding to the display screen exceeds a predetermined threshold value, and when the number of pixel changes is less than or equal to the predetermined threshold value, it is determined that a predetermined change occurs in the display screen, and when the number of pixel changes When the number is greater than the predetermined threshold, it is determined that an unscheduled change occurs in the display screen.

Specifically, the change of the display screen is, for example, switching the touch display screen 10 between landscape display and portrait display. When the touch display screen 10 is switched between landscape display and portrait display, the display content such as the icon of the application program on the touch display screen 10 will change. Correspondingly, the display brightness and corresponding The pixels of the position also change accordingly. The greater the brightness of the touch screen 10 , the greater the capacitance of the touch screen 10 , and the more the pixels at the corresponding positions change, the greater the capacitance of the touch screen 10 . At this time, due to a large change in the display screen of the touch display screen 10, the capacitance value output by each part of the touch display screen 10 changes abruptly, so that the output signal of the touch display screen 10 cannot accurately indicate whether the touch display screen 10 is covered. , may cause false triggering of the state of touching the display screen 10 .

Therefore, it is necessary to determine whether a predetermined change occurs by detecting the degree of change of the display screen of the touch display screen 10. When a predetermined change occurs, the change of the capacitance value of the touch display screen 10 is considered to be highly reliable, that is, The change of the capacitance value can be used for proximity detection, and when there is no predetermined change, it is considered that the screen change has a great influence on the capacitance value, and it is not suitable to use the touch display screen 10 for proximity detection.

The number of pixel changes refers to the number of pixels corresponding to the display screen that change at the current moment after the electronic device 100 enters the call service compared to the first moment before the current moment after entering the call service, for example, at the first moment , the screen is displayed in blue. Taking OLED display as an example, all the blue pixels are on, and the red and green pixels are off. When the display screen turns red at the current moment, the blue pixels and green pixels are off, and the red pixels are off. Bright, at this time all the pixels have changed, then the display screen does not have a predetermined change, and the screen change at this time will have a greater impact on the capacitance value of the touch screen 10, and it is not suitable to use the touch screen 10 as the proximity detection at this time.

And if most of the pixels corresponding to the display screen do not change, for example, 70% of the pixels do not change, then the change of the electrical device 100 is considered to be a predetermined change.

It can be understood that the colors on the display screen of the touch screen 10 are determined by the image data in RGB format. The image data in RGB format divides the three color channels of red, green and blue into 255 levels of brightness respectively. For example, if the RGB data corresponding to a certain color is (0,0,0), then the display screen will appear black. For another example, if the RGB data corresponding to a certain color is (255, 255, 255), then the display screen will appear white. As mentioned above, specific RGB data corresponds to specific colors. The change of the display screen mentioned in the article can be understood as the color change of the pixel at the same position at different times before and after.

The predetermined threshold value in the step can be set according to the screen specification of the touch display screen 10 , or can be uniformly set according to a percentage, which is not specifically limited.

Referring to Figure 23, in some embodiments, the control method includes:

S16: When the change trend does not conform to the predetermined trend, determine whether the temperature of the environment where the electronic device is located has a predetermined change.

In such an embodiment, S16 includes:

S161: Determine whether the difference between the current ambient temperature and the first ambient temperature when the electronic device is in a non-communication state exceeds a predetermined temperature threshold;

S162: When the difference is less than or equal to a predetermined temperature threshold, determine that a predetermined change occurs in the temperature of the environment where the electronic device is located;

S163: When the difference is greater than the predetermined temperature threshold, determine that an unpredetermined change occurs in the temperature of the environment where the electronic device is located.

In some implementations, step S16 may be implemented by the processing module 220, or in other words, the processing module 220 is configured to determine whether the temperature of the environment where the electronic device is located has a predetermined change when the change trend does not conform to the predetermined trend.

In some implementations, the processor 23 is configured to determine whether the temperature of the environment where the electronic device is located has a predetermined change when the change trend does not conform to the predetermined trend.

In such an embodiment, steps S161-S163 may be implemented by the processing module 220, or in other words, the processing module 220 is used to determine whether the difference between the current ambient temperature and the first ambient temperature when the electronic device is in the non-call state exceeds the temperature Predetermined threshold, when the difference is less than or equal to the temperature predetermined threshold, it is determined that the temperature of the environment where the electronic device is located has a predetermined change, and when the difference is greater than the temperature predetermined threshold, it is determined that the temperature of the environment where the electronic device is located has an unscheduled change.

In such an embodiment, the processor 23 is used to determine whether the difference between the current ambient temperature and the first ambient temperature when the electronic device is in the non-call state exceeds a predetermined temperature threshold, and when the difference is less than or equal to the predetermined temperature threshold, It is determined that a predetermined change occurs in the temperature of the environment where the electronic device is located, and when the difference is greater than a predetermined temperature threshold, it is determined that an unscheduled change occurs in the temperature of the environment where the electronic device is located.

Specifically, when the difference is less than or equal to a predetermined temperature threshold, the electronic device 100 can use the touch screen 10 to perform proximity detection, and when the difference is greater than the predetermined threshold, the temperature change at this time will affect the capacitance value of the touch screen 10 The impact is relatively large, and it is not suitable to use the touch display screen 10 as the approach detection at this time.

The predetermined threshold value of the temperature difference can be specified according to the characteristics of temperature change and capacitance change. Generally, the predetermined threshold value can be set according to the electrical performance parameters of the touch screen before leaving the factory, that is, it is found that the temperature change begins to cause large fluctuations in capacitance. The affected temperature value is a predetermined threshold with the temperature difference or a value slightly smaller than the temperature difference. For example, the predetermined threshold may be 25 degrees. In a cold outdoor environment, when the electronic device 100 is in the pocket, the ambient temperature may be 20 degrees. When the user takes out the electronic device 100 and performs a call service, the ambient temperature may be -10 degrees. At this time, the temperature difference of 30 degrees is greater than the predetermined threshold, and at this time, it is not suitable to use the touch screen 10 as the proximity detection.

In this embodiment, the electronic device 100 also includes a temperature sensor, and the temperature sensor is used to obtain the ambient temperature. The first ambient temperature may be the temperature at a certain moment when the electronic device 100 is in a non-call service, or it may be obtained within a certain period of time. Average of multiple ambient temperature values. For example, when the electronic device is in a standby state, the temperature sensor can obtain the first ambient temperature in the background.

Referring to Figure 24, in some embodiments, the control method includes:

S17: When the change does not conform to the predetermined trend, increase the power supply voltage of the touch display screen.

In some implementations, step S17 can be implemented by the processing module 220, or in other words, the processing module 220 is used to determine whether the temperature of the environment where the electronic device is located has a predetermined change when the change trend does not meet the predetermined trend.

In some implementations, the processor 23 is configured to determine whether the temperature of the environment where the electronic device is located has a predetermined change when the change trend does not meet the predetermined trend.

Specifically, in the actual operation process, the self-capacitance signal may change suddenly due to interference factors, so that it no longer has a continuous change trend. Action, and when the proximity signal is detected again after increasing the power supply voltage, the change range of the self-capacitance signal will increase. Relatively, the influence of the change of external factors on the entire trend will be reduced, so that it will not interfere with the process of the proximity action. The trend of continuous change of the self-capacitance signal makes the approach action can be accurately judged.

Before the power supply voltage is increased, the power supply voltage of the touch screen 10 is generally about 3V, and the power supply voltage after the increase is generally determined by the driving IC of the touch screen 10 , for example, it can be 4V.

In such an embodiment, the control method further includes:

S18: collect the output signal of the touch display screen after increasing the power supply voltage;

S19: When the output signal changes after the power supply voltage is increased, determine whether the change trend conforms to the predetermined trend;

S20: When the change trend conforms to the predetermined trend, control the display state of the touch screen according to the output signal after the power supply voltage is increased.

In some implementations, S18 may be implemented by the collection module 210 , S19 may be implemented by the processing module 220 , and S20 may be implemented by the control module 230 . In other words, the collection module 210 is used to collect the output signal of the touch display screen 10 after the power supply voltage is increased. The processing module 220 is used for judging whether the change trend conforms to a predetermined trend when the output signal changes after the power supply voltage is increased. The control module 230 is used to control the display state of the touch screen according to the output signal after the power supply voltage is increased when the change trend conforms to the predetermined trend.

In some embodiments, the processor 23 is used to collect the output signal of the touch display screen 10 after the power supply voltage is increased, and when the output signal after the power supply voltage is increased changes, it is judged whether the change trend conforms to the predetermined trend and whether the change trend conforms to the predetermined trend. When trending, control the display state of the touch screen according to the output signal after increasing the power supply voltage

Specifically, it can be understood that since the voltage that the driver IC can provide is limited, after increasing the supply voltage, it is still necessary to judge whether the change trend of the output signal after the increased voltage during the process of the approaching action conforms to the predetermined trend. If it conforms to the predetermined trend, Proximity detection can be performed according to the output signal, and if the predetermined trend is still not met, the proximity detection is realized by the proximity sensor 16 , thereby controlling the display of the touch screen 10 .

In some embodiments, the control method also includes:

S21: When the change does not conform to the predetermined trend, control the display state of the touch screen according to the signal of the proximity sensor.

In some implementations, step S21 can be implemented by the control module 230, or in other words, the control module 230 is used to control the display state of the touch screen according to the signal of the proximity sensor when the change does not conform to the predetermined trend.

In some implementations, the processor 23 is configured to control the display state of the touch screen according to the signal of the proximity sensor when the change does not conform to the predetermined trend.

Specifically, as mentioned above, if the change does not conform to the predetermined trend, it may be due to many factors such as brightness change, adhered liquid, display screen change, and environmental temperature change that the change of the output signal of the touch display screen during proximity detection does not conform to the predetermined trend. That is, it is not possible to perform proximity detection with a touch screen. At this time, the proximity detection needs to be realized by a proximity sensor.

In this embodiment, the proximity sensor 16 can be turned on after the user puts the electronic device 100 to the ear in conjunction with the output data of the gravity sensor, gyroscope, etc., that is, the user puts the electronic device 100 to the ear. Before, the proximity sensor 16 is turned off. Therefore, before the user puts the electronic device 100 to the ear, there will be no flickering phenomenon when the user observes the touch display screen 10 , which will not reduce the user experience.
