Background technique

Proximity sensors are provided on most terminals. The proximity sensor is set to prevent the user's face from accidentally triggering the display when the user holds the terminal display close to the ear for a call.

detailed description

Referring to the drawings, wherein like reference numerals represent like components, the principles of the present invention are exemplified when implemented in a suitable computing environment. The following description is based on illustrated specific embodiments of the invention, which should not be construed as limiting other specific embodiments of the invention not described in detail herein.

Details will be given below.

An embodiment of the present invention provides a proximity detection method, which is applied to a terminal. The terminal includes a display screen, a casing, and a temperature sensor. A functional hole is opened at the frame of the casing, and the temperature sensor is accommodated in the functional hole. .

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a position of a functional hole in a terminal provided by an embodiment of the present invention. In one embodiment, the functional hole for accommodating the temperature sensor can be opened at a position near the terminal receiver (earpiece) on the upper frame of the housing, as in position A in FIG. 1 .

Of course, in other embodiments, the functional hole for accommodating the temperature sensor can also be opened at other positions corresponding to the upper frame of the housing at the upper end of the display screen, such as position B or C shown in FIG. 2 .

Alternatively, the functional hole for accommodating the temperature sensor may also be provided on the right frame of the housing (with the direction of the display screen facing the user as the front direction of the terminal), as shown in position D in FIG. 3 .

Alternatively, the functional hole for accommodating the temperature sensor can also be opened on the left side frame of the housing, as shown at position E on the left side frame of the terminal in FIG. 4 .

Please refer to FIG. 5. FIG. 5 is a schematic flow diagram of an approach detection method provided by an embodiment of the present invention. The flow may include:

In step S101, when it is detected that the terminal is in a talking state, a first temperature value is acquired through a temperature sensor.

It can be understood that the execution subject of this embodiment of the present invention may be a terminal device such as a mobile phone or a tablet computer.

For example, a terminal display screen includes a display area and a non-display area. The proximity sensor of the terminal is generally arranged in a non-display area at the top of the display screen. For example, the proximity sensor is placed around the receiver, such as on the left or right side. However, since the proximity sensor includes a signal transmitter and a signal receiver, the proximity sensor has a large volume. This requires a larger non-display area to be reserved on the display screen. This reduces the screen-to-body ratio of the terminal display.

In step S101 of the embodiment of the present invention, when it is detected that the terminal is in a talking state, the terminal may obtain a first temperature value through a temperature sensor accommodated in the function hole. For example, the functional hole may be opened at a position corresponding to the upper frame of the housing at the upper end of the display screen and close to the receiver, as shown in FIG. 1 . The first temperature value is also the ambient temperature value acquired by the temperature sensor.

In step S102, it is determined whether the first temperature value is within a preset temperature range, and the preset temperature range is a temperature range of a human body surface.

For example, after acquiring the first temperature value, the terminal may determine whether the first temperature value is within a preset temperature range. The preset temperature range is the temperature range of the human body surface.

In an implementation manner, the preset temperature range may be a temperature range of a human ear, for example, 36.2°-37.2°. For example, the terminal may acquire multiple temperature value samples of human ears in advance, and then generate a temperature range according to these temperature value samples, and determine the temperature range as a preset temperature range, and so on.

Of course, in other implementation manners, the preset temperature range may also be the temperature range of other parts of the human body. For example, the preset temperature range is the temperature range of the face of a human body, etc., and the example here does not constitute a limitation to the present invention.

If it is determined that the first temperature value is not within the preset temperature range, the terminal may control the display screen to enter a bright screen state, ie step S104.

In step S103, if it is determined that the first temperature value is within a preset temperature range, the display screen of the control terminal enters a sleep state.

For example, if it is determined that the first temperature value is within the preset temperature range, that is, the first temperature value is within the temperature range of the user's ear, then it can be considered that the user puts the terminal close to the ear to make a call, and the terminal can control the The display screen enters a dormant state (that is, the screen off state), so as to prevent the user's face from accidentally triggering the terminal display screen.

For example, when the terminal enters the call state, the first temperature value acquired by the terminal is 36.5°, and the preset temperature range is 36.2°-37.2°, then the terminal will determine that the first temperature value enters the preset temperature range. At this time, it can be considered that the user puts the terminal display screen close to the ear to make a call. In this case, the terminal can control the display to enter a sleep state, so as to prevent the user's face from triggering the display by mistake.

In one embodiment, if it is determined in step S103 that the first temperature value is within the preset temperature range, controlling the display screen of the terminal to enter a sleep state may include:

If it is determined that the first temperature value is within a preset temperature range, then obtain a second temperature value obtained by a temperature sensor within a preset time range before the terminal enters a call state, and the temperature sensor obtains a temperature value according to a preset time interval;

If it is detected that the second temperature value is not within the preset temperature range, the display screen of the control terminal enters a sleep state.

For example, the first temperature value acquired by the terminal is 36.5°, and the first temperature value is within a preset temperature range of 36.2°-37.2°. In this case, the terminal may also obtain the second temperature value obtained by the temperature sensor within a preset time range before entering the call state. For example, the terminal acquires the second temperature value acquired through the temperature sensor within 2 seconds or 3 seconds before entering the call state. In one embodiment, the temperature sensor can acquire the temperature value at a preset time interval, for example, the preset time interval is 1.5 seconds, that is, the temperature sensor acquires the temperature value every 1.5 seconds. In an implementation manner, the preset time range is greater than the preset time interval.

After acquiring the second temperature value, if it is detected that the second temperature value is not within the preset temperature range, the terminal may control the display screen to enter a sleep state. For example, the second temperature value is 25°.

That is to say, if the temperature value obtained by the temperature sensor changes from 25° to 36.5° during the process of the terminal entering the call state from the non-call state, that is, the temperature value obtained by the temperature sensor changes from not being in the ear temperature range to 36.5°. If it is within the temperature range of the ear, it can be considered that the user puts the terminal close to the ear when answering the call. In this case, the display can be controlled to sleep.

It can be understood that, by acquiring the temperature values (that is, the second temperature value and the first temperature value) before and after the terminal enters the call state, and detecting whether the two temperature values are within the preset temperature range, the terminal can be more accurately To judge whether the user is talking with the terminal close to the ear to prevent misjudgment.

It can be understood that the embodiment of the present invention can realize the proximity judgment when the terminal is in the talking state by using the temperature sensor, that is, the embodiment of the present invention can use the temperature sensor instead of the proximity sensor. Since the temperature sensor in the embodiment of the present invention can be arranged on the frame of the terminal instead of on the display screen, the area occupied by the display screen can be reduced. Therefore, the embodiment of the present invention can achieve proximity detection while improving the efficiency of the terminal. The screen-to-body ratio of the display.

Please refer to FIG. 6. FIG. 6 is another schematic flow diagram of the approach detection method provided by the embodiment of the present invention. The flow may include:

In step S201, when it is detected that the terminal is in a call state, the terminal obtains a first temperature value through a temperature sensor.

For example, when it is detected that the terminal is in a call state, the terminal may trigger the temperature sensor accommodated in the function hole, and obtain the first temperature value. For example, the functional hole may be provided on the upper frame of the housing corresponding to the upper end of the display screen and close to the receiver, as shown in FIG. 1 .

In step S202, the terminal determines whether the first temperature value is within a preset temperature range, and the preset temperature range is a temperature range of a human body surface.

For example, after acquiring the first temperature value, the terminal may determine whether the first temperature value is within a preset temperature range. The preset temperature range is the temperature range of the human body surface. For example, in one embodiment, the preset temperature range is the temperature range of the human ear, such as 36.2°-37.2°.

If the terminal determines that the first temperature value is not within the preset temperature range, for example, the first temperature value obtained by the terminal is 26°, it may be considered that the user does not put the terminal close to the ear to make a call. In this case, the terminal may control the display screen to enter a bright screen state, that is, step S207.

If the terminal determines that the first temperature value is within the preset temperature range, then enter step S203.

In step S203, if it is determined that the first temperature value is within the preset temperature range, the terminal obtains the second temperature value obtained through the temperature sensor within the preset time range before entering the call state, and the temperature sensor is set at a preset time interval Get the temperature value.

For example, the terminal acquires a first temperature value of 36.5°, and determines that the first temperature value of 36.5° is within a preset temperature range of 36.2°-37.2°. At this time, the terminal may also obtain the second temperature value obtained through the temperature sensor within a preset time range before the terminal enters the call state. For example, the terminal acquires the second temperature value acquired through the temperature sensor within 2 seconds or 3 seconds before entering the call state. In one embodiment, the temperature sensor can acquire the temperature value at a preset time interval, for example, the preset time interval is 1.5 seconds, that is, the temperature sensor acquires the temperature value every 1.5 seconds. In an implementation manner, the preset time range is greater than the preset time interval.

After acquiring the second temperature value, the terminal may detect whether the second temperature value is within a preset temperature range.

If the terminal detects that the second temperature value is not within the preset temperature range, then enter step S204.

If the terminal detects that the second temperature value is within the preset temperature range, then enter step S205.

In step S204, if the terminal detects that the second temperature value is not within the preset temperature range, the terminal controls the display screen to enter a sleep state.

For example, the second temperature value acquired by the terminal through the temperature sensor within 2 seconds before it enters the call state is 25°, and the first temperature value is 36.5°. That is to say, when the terminal enters the call state from the non-call state, the temperature value obtained by the temperature sensor changes from 25° to 36.5°, that is, the temperature value obtained by the temperature sensor changes from not in the ear temperature range to If it is in the ear temperature range, it can be considered that the user puts the terminal close to the ear when answering the call. In this case, the display can be controlled to sleep.

In step S205, if the terminal detects that the second temperature value is within a preset temperature range, the terminal acquires the output data of the gyroscope sensor.

For example, the terminal acquires a second temperature value of 36.3°, and detects that the second temperature value is also within a preset temperature range of 36.2°-37.2°. For example, if the user is outside and the outdoor ambient temperature is relatively high, then the second temperature value obtained when the terminal is not in a call state is the current outdoor ambient temperature. In this case, since the first temperature value is very close to the second temperature value, it is not easy to determine whether the user puts the terminal close to the ear to make a call.

In this case, the terminal can also trigger and obtain the output data of the gyroscope sensor. It should be noted that the gyro sensor is a positioning and control system based on spatial movement and gestures. The output data of the gyro sensor is the angular acceleration data of the X, Y, and Z axes. The gesture of the user holding the terminal can be detected by the gyroscope sensor.

In step S206, when it is detected that the output data of the gyroscope sensor is within the preset range of the preset data, the terminal controls the display screen to enter a sleep state. The preset data is the gyroscope acquired in advance when the user puts the terminal against the ear. The data output by the instrument sensor.

For example, after obtaining the output data of the gyroscope sensor, for example, the output data of the gyroscope sensor at this time is (x1, y1, z1), the terminal can detect whether the gyroscope sensor (x1, y1, z1) is in the preset data preset range. The preset data is the data output by the gyro sensor acquired in advance when the user puts the terminal close to the ear.

In an implementation manner, the terminal may pre-prompt the user to put the terminal close to the ear to simulate a gesture of making a call, and then the terminal may acquire the output data of the gyroscope under the gesture, for example (x0, y0, z0).

If the terminal detects that the output data (x1, y1, z1) of the gyro sensor is within the preset range of the preset data (x0, y0, z0), then it can be considered that the user's gesture at this time is when the terminal is close to the ear. gestures. In this case, the terminal can control the display screen to enter a sleep state.

If the terminal detects that the output data (x1, y1, z1) of the gyro sensor is not within the preset range of the preset data (x0, y0, z0), then it can be considered that the user's gesture at this time is not putting the terminal close to the ear time gestures. In this case, the terminal can control the display screen to enter the bright screen state.

In another embodiment, the terminal may also use the following steps to determine whether the user puts the terminal close to the ear for a call, that is, after detecting in step S201 that the terminal enters the call state, the terminal may also perform the following steps:

The terminal acquires the first light intensity value and the second light intensity value within a preset time range before the terminal enters the call state through the light sensing sensor, and the light sensor acquires the light intensity value at preset time intervals.

In one embodiment, the light sensor can acquire the temperature value at a preset time interval, for example, the preset time interval is 1.5 seconds, that is, the light sensor acquires the temperature value every 1.5 seconds. In an implementation manner, the preset time range is greater than the preset time interval. For example, the preset time range is within 2 seconds, and the preset time interval is 1.5 seconds.

Based on this, when the terminal determines that the first temperature value is within the preset temperature range, the terminal can calculate the difference between the second light intensity value and the first light intensity value, and detect whether the difference is greater than or equal to the preset light intensity difference value threshold.

If the terminal detects that the difference between the second light intensity value and the first light intensity value is greater than or equal to the preset light intensity difference threshold when it is determined that the first temperature value is within the preset temperature range, the terminal can control the display screen to enter dormant state.

That is to say, when it is detected that the terminal enters the call state, in addition to triggering the temperature sensor to obtain the first temperature value, the terminal can also obtain the first light intensity value at this time by triggering the light sensor, and the preset value before the terminal enters the call state. The second light intensity value in the time range. For example, the light intensity value within 2 seconds or 3 seconds before the terminal enters the talking state, that is, the second light intensity value.

Afterwards, if the terminal determines that the first temperature value is within the preset temperature range, that is, the terminal determines that the first temperature value is within the preset human ear temperature range, then the terminal can calculate the second light intensity value and the first light intensity value and judge whether the difference is greater than or equal to the preset light intensity difference threshold.

Since the light sensor is generally also arranged around the receiver on the upper end of the display screen, when the user does not put the terminal close to the ear, the environment where the light sensor is located is brighter, and the light intensity value detected by it is larger. When the user puts the terminal close to the ear, since the ear is blocked in front of the light sensor, the light sensor will enter a darker environment, and the light intensity value detected by it will correspondingly become smaller.

Therefore, if it is determined that the difference between the second light intensity value and the first light intensity value is greater than or equal to the preset light intensity difference threshold, it can be considered that when the terminal enters the call state from the non-call state, the light sensor of the terminal The environment changes from brighter to darker, and the change in ambient brightness is large. In this case, it can be considered that the user puts the terminal close to the ear, and at this time, the display screen can be controlled to enter the sleep state.

If the terminal detects that the difference between the second light intensity value and the first light intensity value is less than the preset light intensity difference threshold when it is determined that the first temperature value is within the preset temperature range, the terminal can control the display screen to enter the bright screen state.

It can be understood that by using the light sensor to assist the temperature sensor in judging whether the user puts the terminal close to the ear, misjudgment by the terminal on proximity judgment can be reduced.

In one embodiment, after the step of the terminal controlling the display screen to enter the dormant state, the following steps may also be included:

The terminal obtains the third temperature value through the temperature sensor;

If it is detected that the third temperature value is not within the preset temperature range, the terminal controls the display screen to enter a bright screen state.

For example, after controlling the display screen to enter the dormant state, the terminal can also obtain the temperature value of the environment where the temperature sensor is located, that is, the third temperature value through the temperature sensor, and detect whether the third temperature value is still within the preset temperature range.

If it is detected that the third temperature value is still within the preset temperature range, the terminal may continue to keep the display screen in a dormant state.

If it is detected that the third temperature value deviates from the preset temperature range, the terminal may control the display screen to enter a bright screen state. For example, since the user no longer puts the terminal close to the ear, the temperature value acquired by the terminal through the temperature sensor is no longer in the preset temperature range, and at this time the terminal can control the display to enter the bright screen state.

It should be noted that, in another implementation manner, when the terminal detects that the first temperature value acquired by the temperature sensor is within the preset temperature range, the terminal may also directly acquire the output data of the gyroscope sensor, and upon detecting the When the output data of the gyroscope is within the preset range of the preset data, the display screen of the control terminal enters a sleep state. It is not necessary to obtain the second temperature value through the temperature sensor within a preset time range before the terminal enters the call state.

Please refer to FIG. 7 . FIG. 7 is a schematic structural diagram of an approach detection device provided by an embodiment of the present invention. The proximity detection device is applied to a terminal, and the terminal includes a display screen, a housing, and a temperature sensor. A functional hole is opened at the frame of the housing, and the temperature sensor is accommodated in the functional hole. The proximity detection device 300 may include: a first acquiring A module 301 , a judging module 302 , and a first control module 303 .

The first obtaining module 301 is configured to obtain a first temperature value through a temperature sensor when it is detected that the terminal enters a call state.

For example, when it is detected that the terminal enters a call state, the first acquisition module 301 of the terminal may acquire the first temperature value through the temperature sensor accommodated in the function hole. For example, the functional hole may be provided on the upper frame of the housing corresponding to the upper end of the display screen and close to the receiver, as shown in FIG. 1 .

A judging module 302, configured to judge whether the first temperature value is within a preset temperature range, and the preset temperature range is a temperature range of a human body surface.

For example, after the first acquiring module 301 acquires the first temperature value, the judging module 302 can judge whether the first temperature value is within a preset temperature range. The preset temperature range is the temperature range of the human body surface.

In an implementation manner, the preset temperature range may be a temperature range of a human ear, for example, 36.2°-37.2°.

The first control module 303 is configured to control the display screen of the terminal to enter a sleep state if it is determined that the first temperature value is within a preset temperature range.

For example, if the judging module 302 judges that the first temperature value is within the preset temperature range, that is, the first temperature value is within the temperature range of the user's ear, then it can be considered that the user puts the terminal close to the ear to make a call. The first control module 303 can control the display screen to enter a dormant state (that is, a screen-off state), so as to prevent the user's face from accidentally triggering the terminal display screen.

For example, when the terminal enters the call state, the first temperature value acquired by the first acquisition module 301 is 36.5°, and the preset temperature range is 36.2°-37.2°, then the judging module 302 will judge that the first temperature value has entered the preset temperature range. Set temperature range. At this time, it can be considered that the user puts the terminal display screen close to the ear to make a call. In this case, the first control module 303 may control the display screen to enter a sleep state, so as to prevent the user's face from triggering the display screen by mistake.

In one embodiment, the first control module 303 can be used for:

If it is determined that the first temperature value is within a preset temperature range, then obtain a second temperature value obtained by a temperature sensor within a preset time range before the terminal enters a call state, and the temperature sensor obtains a temperature value according to a preset time interval;

If it is detected that the second temperature value is not within the preset temperature range, the display screen of the control terminal enters a sleep state.

For example, the first temperature value acquired by the first acquisition module 301 is 36.5°, and the first temperature value is within the preset temperature range of 36.2°˜37.2°. In this case, the first control module 303 may also obtain the second temperature value obtained by the temperature sensor within a preset time range before the terminal enters the talking state. For example, the first control module 303 acquires the second temperature value obtained by the temperature sensor within 2 seconds or 3 seconds before the terminal enters the talking state. In one embodiment, the temperature sensor can acquire the temperature value at a preset time interval, for example, the preset time interval is 1.5 seconds, that is, the temperature sensor acquires the temperature value every 1.5 seconds. In an implementation manner, the preset time range is greater than the preset time interval. For example, the preset time range is 2 seconds, and the preset time interval is 1.5 seconds.

After acquiring the second temperature value, if the first control module 303 detects that the second temperature value is not within the preset temperature range, the first control module 303 may control the display screen to enter a sleep state. For example, the second temperature value is 25°.

That is to say, if the temperature value obtained by the temperature sensor changes from 25° to 36.5° during the process of the terminal entering the call state from the non-call state, that is, the temperature value obtained by the temperature sensor changes from not being in the ear temperature range to 36.5°. If it is within the temperature range of the ear, it can be considered that the user puts the terminal close to the ear when answering the call. In this case, the first control module 303 may control the display screen to enter a sleep state.

Please refer to FIG. 8 together. FIG. 8 is another schematic structural diagram of the proximity detection device provided by the embodiment of the present invention. In an embodiment, the approach detection device 300 may further include: a second control module 304 , a second acquisition module 305 , and a third acquisition module 306 .

The second control module 304 is configured to acquire the output data of the terminal gyroscope sensor if it is detected that the second temperature value is in the preset temperature range; when it is detected that the output data of the gyroscope sensor is in the preset data range When within the preset range, the terminal display screen is controlled to enter a sleep state, and the preset data is the data output by the gyroscope sensor acquired in advance when the user puts the terminal close to the ear.

For example, the second temperature value acquired by the first control module 303 is 36.3°, and detects that the second temperature value is also within the preset temperature range of 36.2°-37.2°. For example, if the user is outside and the outdoor ambient temperature is relatively high, then the second temperature value obtained when the terminal is not in a call state is the current outdoor ambient temperature. In this case, since the first temperature value is very close to the second temperature value, it is not easy to determine whether the user puts the terminal close to the ear to make a call.

In this case, the output data of the gyro sensor can be acquired by the second control module 304 . It should be noted that the gyro sensor is a positioning and control system based on spatial movement and gestures. The output data of the gyro sensor is the angular acceleration data of the X, Y, and Z axes. The gesture of the user holding the terminal can be detected by the gyroscope sensor.

For example, after the second control module 304 acquires the output data of the gyro sensor, for example, the output data of the gyro sensor is (x1, y1, z1), the second control module 304 can detect the gyro sensor (x1, y1, z1) is in the preset range of the preset data. The preset data is the data output by the gyro sensor acquired in advance when the user puts the terminal close to the ear.

In an implementation manner, the terminal may pre-prompt the user to put the terminal close to the ear to simulate a gesture of making a call, and then the terminal may acquire the output data of the gyroscope under the gesture, for example (x0, y0, z0).

If the second control module 304 detects that the output data (x1, y1, z1) of the gyro sensor is within the preset range of the preset data (x0, y0, z0), then it can be considered that the user's gesture at this time is to turn the terminal Gestures when placed close to the ear. In this case, the second control module 304 may control the display screen to enter a sleep state.

If the terminal detects that the output data (x1, y1, z1) of the gyro sensor is not within the preset range of the preset data (x0, y0, z0), then it can be considered that the user's gesture at this time is not putting the terminal close to the ear time gestures. In this case, the terminal can control the display screen to enter the bright screen state.

The second acquisition module 305 is configured to acquire the first light intensity value and the second light intensity value within the preset time range before the terminal enters the call state through the light sensor sensor, and the light sensor acquires the light intensity at preset time intervals value.

Based on this, the first control module 303 is configured to calculate the difference between the second light intensity value and the first light intensity value if it is determined that the first temperature value is within a preset temperature range; If the difference is greater than or equal to the preset light intensity difference threshold, the display screen of the control terminal enters a dormant state.

For example, when it is detected that the terminal enters the call state, in addition to triggering the first acquisition module 301 to acquire the first temperature value through the temperature sensor, the second acquisition module 305 can also be triggered to acquire the first light intensity value at this time through the light sensor, And the second light intensity value within the preset time range before the terminal enters the talking state. For example, the light intensity value within 2 seconds or 3 seconds before the terminal enters the talking state, that is, the second light intensity value. In one embodiment, the light sensor can acquire the temperature value at a preset time interval, for example, the preset time interval is 1.5 seconds, that is, the light sensor acquires the temperature value every 1.5 seconds. In an implementation manner, the preset time range is greater than the preset time interval. For example, the preset time range is 2 seconds, and the preset time interval is 1.5 seconds.

Afterwards, if the terminal determines that the first temperature value is within the preset temperature range, that is, the terminal determines that the first temperature value is within the preset human ear temperature range, then the first control module 303 may calculate the second light intensity value and the second light intensity value. a light intensity difference, and determine whether the difference is greater than or equal to a preset light intensity difference threshold.

Since the light sensor is generally also arranged around the receiver on the upper end of the display screen, when the user does not put the terminal close to the ear, the environment where the light sensor is located is brighter, and the light intensity value detected by it is larger. When the user puts the terminal close to the ear, since the ear is blocked in front of the light sensor, the light sensor will enter a darker environment, and the light intensity value detected by it will correspondingly become smaller.

Therefore, if it is determined that the difference between the second light intensity value and the first light intensity value is greater than or equal to the preset light intensity difference threshold, it can be considered that when the terminal enters the call state from the non-call state, the light sensor of the terminal The environment changes from brighter to darker, and the change in ambient brightness is large. In this case, it can be considered that the user puts the terminal close to the ear, and at this time the first control module 303 can control the display screen to enter a sleep state.

If the terminal detects that the difference between the second light intensity value and the first light intensity value is less than the preset light intensity difference threshold when it is determined that the first temperature value is within the preset temperature range, the terminal can control the display screen to enter the bright screen state.

The third acquiring module 306 is configured to acquire a third temperature value through the temperature sensor; if it is detected that the third temperature value is not within the preset temperature range, control the display screen of the terminal to enter a bright screen state.

For example, after the terminal controls the display screen to enter the dormant state, the third obtaining module 306 may also be triggered to obtain the temperature value of the environment where the temperature sensor is located, that is, the third temperature value through the temperature sensor, and detect whether the third temperature value is still at Preset temperature range.

If it is detected that the third temperature value is still within the preset temperature range, the terminal may continue to keep the display screen in a dormant state.

If it is detected that the third temperature value deviates from the preset temperature range, the third obtaining module 306 may control the display screen to enter a bright screen state. For example, since the user no longer puts the terminal close to the ear, the temperature value obtained by the terminal through the temperature sensor is no longer in the preset temperature range, and at this time the third obtaining module 306 can control the display screen to enter the bright screen state.
