Fig. 2 schematically shows a schematic structural diagram of a display device according to an embodiment of the present disclosure;
as shown in fig. 2, the display device 200 includes:
the display module 210 can be configured to respond to the display signal and present display content corresponding to the display signal, where the display module can make the display content in a perceived state under irradiation of backlight light;
the optical module 220 can be used for generating light.
The display module 210 may be, for example, a transparent liquid crystal display, and can be used to display a picture, and the picture content can be perceived by a user.
It should be understood by those skilled in the art that the description of "transparent" and "light-transmitting" mentioned in the present disclosure is only used to indicate that the light transmittance of the object is good, and does not refer to the case of 100% light transmittance, for example, the light transmittance may be higher than 60%, or 70%, or 80%, and the user can see the picture behind the object clearly through the object. Similarly, the description related to "non-transparent" and "non-transparent" in this disclosure is only used to indicate that the light transmittance of the object is poor, and does not refer to the case where the light transmittance is 0, and for example, the light transmittance may be lower than 40%, or 30%, or 20%, and the user cannot substantially see the picture behind the object through the object.
Fig. 3 schematically illustrates a structural schematic view of another viewing angle of the display device 200 according to an embodiment of the present disclosure;
as shown in fig. 3, according to the embodiment of the disclosure, the optical module has a light emitting surface 221 capable of outputting a backlight light set, and the light incident surface 211 of the display module is disposed within an irradiation range of the light set.
For example, one side of the display module is the display surface 212, that is, the side for outputting display content, and a user can see a display picture on the display surface 212; the surface of the display module opposite to the display surface 212 is a light incident surface 211, i.e. the surface on which the backlight light is incident, and the light incident surface 211 of the display module is also referred to as the back surface of the display module.
The optical module 220 may be stacked on the back of the display module 210, for example, the light emitting surface of the optical module 220 is opposite to the light incident surface of the display module 210, and the two may be attached to each other or separated by a certain distance. It should be understood that the optical module 220 and the display module 210 may be arranged in other manners as long as the light emitted from the light emitting surface of the optical module 220 can be irradiated onto the light incident surface 211 of the display module, which is not limited in this disclosure.
Those skilled in the art will appreciate that the directions of the rays shown in the drawings are merely examples, and that in practical scenarios, the rays may diverge in any direction.
According to an embodiment of the present disclosure, the display apparatus 200 has at least a first state in which the light generated by the optical module 220 is used as backlight light and a second state; in the second state, the light outside the display device 200 acts as backlight light.
Among other things, the display device 200 may switch its state based on the brightness of ambient light or user selection, among other conditions. The ambient light is light outside the display device 200.
For example, under the condition that the ambient light is sufficient, the brightness of the light outside the display device 200 is high, so that the display module 210 can present a good display effect, and the display device 200 can be controlled to be in the second state. In the second state, the optical module 220 does not emit light and is transparent, and the ambient light can be incident into the display module 210 through the optical module 220. Alternatively, in the case where the ambient light is insufficient, the display device 200 may be controlled to be in the first state. In the first state, the optical module 220 is activated to generate light, so that the light is incident into the display module 210, in this case, the optical module 220 may be in a non-transparent state in all regions corresponding to the display module 210, or in a transparent state in a partial region, and in a non-transparent state in a partial region.
It should be understood that the switching between the first state and the second state may also be based on a user operation.
FIG. 4 schematically shows a schematic diagram of displaying content on a display device according to an embodiment of the disclosure;
as shown in fig. 4, the display module 210 is capable of receiving the display signal and displaying the display content 211 in the corresponding area based on the display signal. The display content 211 has a visually blocking effect, so that the area of the display module 210 where the display content is displayed is in a non-transparent state, and the area where the display content is not displayed is in a transparent state.
According to an embodiment of the present disclosure, in the first state and the second state, the light transmittance of the display apparatus 200 in the region corresponding to the display content is lower than or equal to the region other than the corresponding display content in the display apparatus 200.
In the second state, since the optical module 220 is in a transparent state, the transmittance of the display apparatus 200 is related to the display module 210, and since the transmittance of the area on the display module 210 with the display content is lower than the transmittance of the area without the display content, the transmittance of the display apparatus 200 in the area corresponding to the display content is lower than the transmittance of the area other than the area corresponding to the display content in the display apparatus in the second state.
According to an embodiment of the disclosure, in the first state, the optical module 220 may output the backlight light set only in the area corresponding to the display content, and the transmittance of the optical module 220 in the area corresponding to the display content is lower than that in the area other than the area corresponding to the display content. The optical module 220 may emit light in a partial region, and may emit light in a region corresponding to the display content on the display module 210 based on the display signal, and not emit light in other regions. In this case, the area of the optical module 220 corresponding to the display content may be in a non-transparent state, and the other areas may be in a transparent state. Thus, in the first state, the display device, 200, may have a lower light transmittance in regions corresponding to the display content than in regions of the display device other than the corresponding display content.
According to the embodiment of the disclosure, in the first state, the optical module 220 may output the backlight light set in all the regions corresponding to the display module 210, and the transmittance of the optical module 220 in the regions corresponding to the display module in the first state is lower than that in the second state. The area of the optical module 220 corresponding to the display module 210 with the display content and the area without the display content may both be non-transparent, have the same transmittance, and have a lower transmittance. Therefore, the transmittance of the optical module 220 in the first state is lower than that in the second state. In this case, since both the area on the display apparatus 200 where the display content is displayed and the area where the display content is not displayed are in the opaque state, in the first state, the display apparatus 200 may have the light transmittance in the area corresponding to the display content equal to the area of the display apparatus 200 other than the area corresponding to the display content. The display device 200 may be used as a conventional non-transparent display screen.
According to an embodiment of the disclosure, the optical module 220 includes a light emitting layer having the light emitting surface, and at least a partial region of the light emitting surface can output the backlight light assembly.
The optical module 220 may be, for example, a light-emitting panel, such as a panel having a plurality of light-emitting units in an array, and the light-emitting side of the light-emitting unit may be the light-emitting surface. The light emitting panel may emit light in a partial area.
FIG. 5 schematically illustrates a schematic diagram of an optical module 220 according to another embodiment of the present disclosure;
as shown in fig. 5, the optical module 220 includes a light source 223 and a light guiding layer 224, the light guiding layer 224 has a light emitting surface, and the light guiding layer 224 can transmit at least a portion of the light emitted from the light source 223 and output the light through the light emitting surface.
For example, the light source 223 can be, for example, an LED light bar, the light guide layer 224 can be, for example, a light guide plate, and the light emitting surface of the light guide layer 224 is the light emitting surface. The light emitted from the light source 223 can at least partially irradiate the light guide layer 224, and is reflected and transmitted to the display module 210 by the bottom surface of the light guide layer 224 or the reflective material disposed in the light guide plate.
FIG. 6 schematically illustrates a schematic diagram of an optical module 220 according to another embodiment of the present disclosure;
as shown in fig. 6, in accordance with an embodiment of the present disclosure, the optical module 220 further includes a color altering layer 225; the transmittance of the color changing layer 225 in the first state is lower than the transmittance in the second state; in the first state, the color changing layer can reflect the light transmitted to the back of the light guide layer back to the light guide layer; in the second state, the color changing layer is capable of transmitting light outside the display device.
The color-changing layer 225 may be, for example, an electrochromic film, and the transmittance of the electrochromic film can be adjusted by powering on and powering off, for example, the electrochromic film can transmit light after powering on and does not transmit light after powering off, or the electrochromic film can transmit light after powering on and does not transmit light after powering off.
In the first state, the optical module 220 is activated, and the electrochromic film can be changed from the transparent state to the non-transparent state after being electrified, so that on one hand, the reflectivity of light emitted by the light source 223 can be increased, the light transmitted to the back surface of the light guide layer 224 is reflected back to the light guide layer 224, and on the other hand, the incident of external environment light can be blocked, so that the optical module 220 is in the non-transparent state. In the second state, the electrochromic film may be in a transparent state, so that light outside the display device can pass through the electrochromic film, and the optical module 220 is in a transparent state.
According to the embodiment of the present disclosure, the display device 200 further has a third state in which the light generated by the optical module 220 and the light outside the display device 200 are used together as backlight light. The transmittance of the area of the optical module 220 corresponding to the display module 210 in the third state is higher than the transmittance in the first state, and is lower than the transmittance in the second state.
In the third state, the optical module 220 may be in a semi-transmissive state, where the semi-transmissive state is between the transmissive state and the non-transmissive state, for example, the light transmittance is between 20% and 80%, or between 30% and 70%, or between 40% and 60%, for example, the light transmittance may be 50%, and a portion of external light can be allowed to pass through the optical module 220 and enter the display module 210. The transmittance of the optical module 220 in the third state is between the transmittance in the first state and the transmittance in the second state.
According to an embodiment of the present disclosure, the display apparatus 200 further has a fourth state in which the display module 210 stops responding to the display signal; the transmittance of the area of the display apparatus 200 corresponding to the display module 210 in the fourth state is equal to the transmittance of the area of the display apparatus outside the corresponding display content in the second state.
In the fourth state, the display module 210 is not used for displaying, for example, in the off state. In this case, the display module 210 and the optical module 220 are both in a transparent state, and the light transmittance of the display apparatus 200 is the same as that of the area thereof in the second state where no content is displayed.
According to an embodiment of the present disclosure, the display device further includes a sensor for sensing brightness of light outside the display device, so that the display device determines a state of the display device based on the brightness of light outside the display device.
The sensor is used for detecting a parameter of the ambient light, and may be, for example, a sensor for detecting light brightness, such as a photosensitive sensor. The sensor may transmit to the processor after sensing the brightness of the ambient light, so that the processor determines whether to turn on the optical module 220 based on the brightness of the ambient light.
The display device may be selected from the first state, the second state and the third state based on the brightness of the ambient light, e.g. in case the ambient light is sufficient (e.g. the brightness value is larger than the first brightness threshold), the second state may be selected; in case the ambient light is insufficient (e.g. the brightness value is less than the second brightness threshold), the second state may be selected; the third state may be selected in case the ambient light is weak but provides part of the light (e.g. a brightness value between the first and second brightness thresholds).
The fourth state is a state in which the display device 200 is turned off, and the display device 200 may obtain a display instruction in this state, and after obtaining the display instruction, it is necessary to obtain the brightness of the ambient light detected by the sensor, so as to determine which state to enter, and then display the display content in the corresponding display state.
During operation in the first, second or third states, the sensor may detect ambient light levels in real time and transmit them to the processor, which determines whether to continue operating the current state or to switch to another state based on the parameters obtained by the sensor.
When the display apparatus 200 is applied to an apparatus door of a closed apparatus, the display state of the display apparatus 200 may be switched according to the opening and closing state of the apparatus door in addition to the ambient light brightness.
According to an embodiment of the present disclosure, the display device 200 is disposed at a first body, the first body and a second body are detachably connected, the first body is movable relative to the second body, the second body has an opening, and the opening is shielded when the first body is at a first position; when the first body is at the second position, the opening is exposed.
The light transmittance of the side wall of the second body is lower than that of the display device in the second state except for the area corresponding to the display content. For example, the sidewall of the second body is opaque or semi-opaque.
When the first body is at the first position and the display device is in the first state, the light rays generated by the optical module are used as backlight light rays;
when the first body is at the second position, the light outside the display device is used as the backlight light when the display device is in the second state.
Wherein, the first body can move relative to the second body can mean that the first body can rotate or slide relative to the second body. For example, the first body is connected with the second body through a rotating shaft, and the first body can pivot relative to the second body; or the first body is connected in the sliding groove of the second body, and the first body can slide relative to the second body.
For example, the first body may be a refrigerator door on which the display device 200 is disposed, and the second body may be a portion of the refrigerator other than the refrigerator door, such as a cabinet having an opening at one side. The refrigerator door is installed at the opening of the refrigerator body. Because the box body is made of opaque materials, the wall surface of the box body can not enable ambient light to penetrate into the box body basically.
Under the closed condition of refrigerator door, a confined space is formed with the box to the refrigerator door, and inside ambient light brightness is lower, can adopt optical module to provide light for display module assembly under this condition, and display device is in the first state. Under the condition that the refrigerator door is opened, light can be emitted into the inner side or the outer side of the refrigerator door, so that the ambient light can be used as backlight light of the display device, and the display device is in the second state.
When the first body can rotate relative to the second body, for example, the refrigerator door can rotate relative to the box body, and when the refrigerator door is closed, a user stands outside the refrigerator door to watch a picture displayed by the display device; after the user opens the refrigerator door, the refrigerator door is rotated certain angle, if the user still stands in the original place, what the user saw is the back of refrigerator door, can lead to like this that the picture that the user watched is reverse, influences user experience.
According to the embodiment of the disclosure, in the first state, the display module displays first display content, so that an image seen from the display device by a viewer on a first side of the display device is matched with the first display content. The first side is an outer surface side of an accommodating space formed by the first body and the second body;
in a second state, the display module displays second display content, and the first display content and the second display content are in mirror images opposite to each other, so that an image seen by a viewer on a second side of the display device from the display device is the same as the first display content. The second side is a surface side of the first body opposite to the first side, that is, an inner surface side of the accommodating space.
For example, since the screen viewed from both sides of the display apparatus by the user is a mirror image, i.e., a screen opposite to the left and right. Therefore, in order for the user to view the same screen from both sides of the display device, it is necessary to adjust the screen on the display device according to the viewing position of the user. For example, when a user views a screen from a first side of the display device, the first display content can be seen, and when the user views the screen from a second side of the display device, the screen on the display device needs to be subjected to mirroring processing, that is, the first display content is subjected to mirroring processing to obtain the second display content and displayed, in this case, the screen viewed from the second side by the user is the same as the screen viewed from the first side before.
For example, in a case where the refrigerator door is closed, the user views an image displayed on the display device from the outside of the refrigerator door, and in a case where the refrigerator door is opened, the user views an image displayed on the display device from the inside of the refrigerator door. Therefore, after the refrigerator door is opened, the picture on the display device needs to be adjusted, for example, mirror-image adjustment, so that the user can view the accurate picture on the inner side of the refrigerator door.
It should be understood that after the refrigerator door is opened by rotation, the user can also move to the front side of the refrigerator door to watch the picture displayed on the display device, and the front side of the refrigerator door is the outer side surface of the refrigerator door, so that the display content of the display device does not need to be adjusted.
