With the continuous development of display technologies, the functions of display panels are increased, and the display panels can further realize a camera function, a fingerprint recognition function and the like in addition to a picture display function. For the existing mobile display products (mobile phones or tablets) on the market, the camera function is one of the key considerations for consumers to select the mobile display products.

At present, mobile terminals such as mobile phones and tablet computers generally have front and rear cameras. In the in-service use of shooing, the use of preceding, rearmounted camera respectively has a weight on the contrary, and the camera module generally includes leading camera module and rearmounted camera module promptly, for guaranteeing the effect of making a video recording, the camera module has a plurality of cameras. The camera unit of most display products is generally installed in a back-loading mode and a front-loading mode. The rear-loading mode is that the prepared display screen and the camera unit are installed in a split mode and connected through a data line to complete the collection of the camera unit and the display screen; for example, the design of the front camera and the rear camera in the existing vehicle-mounted display screen is a rear-mounted type, the front camera can be in a lifting type structure in the rear-mounted type design, and the rear camera is a vehicle event data recorder. The front-mounted type is that holes are dug in a part of the structure of the display screen, such as a backlight assembly, in the manufacturing process of the display screen so as to place photosensitive devices such as a camera unit, namely the design of a common camera under the screen.

However, the existing externally-arranged camera with a rear-mounted design is very complicated and troublesome to use, and the whole machine is thick in structure and large in occupied space. The front-mounted design needs to be provided with a large long hole, and in order to avoid influencing the transmittance, the signal wiring of the display screen needs to completely bypass the perforated area, so that the wiring on the periphery of the perforated area is dense, a short circuit is caused, and if the short circuit is to be avoided, the frame on the periphery of the perforated area is difficult to compress.

Therefore, it is an urgent technical problem to provide a display device that is compatible with a front camera and a rear camera, and is beneficial to reducing the wiring density around the cameras and compressing the peripheral frame of the opening area as much as possible.

the display module 10 at least includes a plurality of signal lines 101, and at least a portion of the signal lines 101 are located in the second area BB 2.

Specifically, the display device 000 provided in this embodiment includes a first display area AA1 and a photosensitive element setting area BB that are adjacently disposed, where the first display area AA1 can be understood as an area where the display device 000 is used for normal display, and the display module 10 in the first display area AA1 can be provided with structures for implementing a display function, such as a driving transistor and a color resistor, which are not described herein again, and the display module 10 can be specifically configured with reference to the type of the display module 10 in the related art. The photosensitive element setting area BB is used to set the photosensitive element 20, and optionally, the photosensitive element 20 may be an identification element such as a camera, a light sensor, a distance sensor, a biosensor, etc., and this embodiment is only exemplified by taking the photosensitive element 20 as a camera. In the present embodiment, the first display area AA1 and the photosensitive element disposing area BB are disposed adjacently, the photosensitive element disposing area BB may be located in an edge region of the entire first display area AA1, that is, the photosensitive element disposing area is disposed adjacently to the first display area AA1 (not shown in the drawings), or the first display area AA1 may also be disposed partially around the photosensitive element disposing area BB, for example, the first display area AA1 is an area including a notch, and the photosensitive element disposing area BB is disposed in the notch (similar to "banglans", not shown in the drawings); alternatively, as shown in fig. 1, the first display area AA1 may also be disposed completely around the photosensitive element disposing area BB, and the relative position relationship between the first display area AA1 and the photosensitive element disposing area BB is not particularly limited in this embodiment, and in the specific implementation, the setting may be selected according to actual requirements.

The photosensitive element setting area BB of this embodiment includes a first area BB1 and a second area BB2, the photosensitive element 20 includes a first photosensitive element 201 and a second photosensitive element 202, the first photosensitive element 201 is located in the first area BB1, the second photosensitive element 202 is located in the second area BB2, a photosensitive surface 201A of the first photosensitive element 201 faces the light emitting surface 10E of the display module 10, that is, the first photosensitive element 201 can be understood as a front camera, and the first area BB1 of the photosensitive element setting area BB can be understood as a setting area of the front camera; the light-sensing surface 202A of the second light-sensing element 202 is away from the light-emitting surface 10E of the display module 10, that is, the second light-sensing element 202 can be understood as a rear camera, and the second area BB2 of the light-sensing element placement area BB can be understood as a placement area of the rear camera. Since the light-sensing surface 201A of the first light-sensing element 201 used as the front camera faces the light-emitting surface 10E of the display module 10, in order to ensure that the front camera can work normally, the light-sensing surface 201A of the first light-sensing element 201 needs to face the light-emitting surface 10E of the display module 10 (the front surface of the display device 000), and at the same time, the information in the environment (such as ambient light, when the first light-sensing element 201 is other light sensors, distance sensors, and biosensors, and other structural information in the environment needs to be collected) needs to be collected, the transmittance of the first area BB1 is set to be greater than that of the second area BB2 in this embodiment, so that the recognition performance of the first light-sensing element 201 can be improved, and the transmittance of the first area BB1 is prevented from affecting the precision of the first light-sensing element 201.

The display module 10 of this embodiment at least includes a plurality of signal lines 101, and optionally, the signal lines 101 may be scan lines for transmitting scan signals, or the signal lines 101 may be data lines for transmitting data voltage signals, or the signal lines 101 may be touch lines for transmitting touch signals, and the like. Since the second photosensitive element 202 is located in the second zone BB2 of the photosensitive element setting zone BB, the photosensitive surface 202A of the second photosensitive element 202 is far away from the light emitting surface 10E of the display module 10, i.e. the second photosensitive element 202 has less light requirement on the light emitting surface 10E of the display module 10 compared to the first photosensitive element 201, and the photosensitive surface 202A of the second photosensitive element 202 can normally operate even if it is far away from the light emitting surface 10E of the display module 10, therefore, in the present embodiment, at least some signal lines 101 in the display module 10 are located in the second zone BB2, so that the available space of the photosensitive element setting zone BB can be fully utilized, at least some signal lines 101 that do not affect the operation of the second photosensitive element 202 are located in the second zone BB2, the wiring pressure around the photosensitive element setting zone BB can be effectively shared, and it is favorable for compressing the size of the wiring frame around the photosensitive element setting zone BB as much as possible, therefore, when the display device 000 is compatible with the front camera and the rear camera, the wiring density around the photosensitive element setting area BB is reduced, the frame around the photosensitive element setting area BB is reduced, more display spaces are provided for the first display area AA1, and the screen occupation ratio is improved.

Optionally, in the present embodiment, at least a part of the signal lines 101 in the display module 10 are located in the second area BB2, which may also be understood as that a part of the signal lines 101 in the plurality of signal lines 101 in the display module 10 are located in the second area BB2 (not shown in the drawings).

It is understood that the number of the photosensitive elements 20 is only exemplarily shown in the figure of the present embodiment, and when the embodiment includes, but is not limited to, the number of the first photosensitive elements 201 and the second photosensitive elements 202 arranged in the photosensitive element arrangement area BB can be selectively arranged according to actual requirements. The shape of the photosensitive element 20 is only exemplarily illustrated in the present embodiment, and in the specific implementation, the shape of the photosensitive element 20 includes but is not limited to this, and can be set according to actual requirements.

It is further understood that, in fig. 1 of the present embodiment, for clarity of illustrating the arrangement position of the photosensitive element 20, when the display module 10 is transparently filled, the photosensitive elements 20 may not be seen from the viewing angle of fig. 1, i.e. the light-emitting surface 10E of the display module 10, that is, the photosensitive elements 20 can be disposed on the backlight side of the display module 10 (the side away from the light emitting surface 10E of the display module 10, as shown in the position of the cross-sectional view of fig. 2), in which the transmittance of the first area BB1 for placing the first photosensitive element 201 is greater than the transmittance of the second area BB2 for placing the second photosensitive element 202, the display module 10 can perform some arrangement for increasing the transmittance at the position of the first zone BB1, if a structure of a high light-transmitting material is adopted, it is avoided that a structure of a light-impermeable material is disposed in the region, and the like, and details are not described herein in this embodiment.

It should be noted that the display device 000 of the present embodiment may be a liquid crystal display device or other types of display devices, and the present embodiment is not particularly limited. The display module 10 of the present embodiment may be a display panel or an integral structure of a display panel and a backlight module, and may be configured according to a specific type of the display device 000 in a specific implementation. Fig. 1 to fig. 3 of the present embodiment are only exemplary diagrams illustrating the structure of the display device 000, which include but are not limited to this, for example, the first display area AA1 used as the normal display area, and the display module 10 may further include other structures capable of implementing a display function, and in a specific implementation, the structure of the display device in the related art may be referred to for understanding, and this embodiment is not described herein again.

The embodiment explains that in some types of display devices 000, such as a vehicle-mounted display, a larger number of light sensing elements 20 may need to be arranged to achieve a better light sensing effect, for example, when the light sensing elements 20 are cameras, a larger number of cameras may be arranged to achieve a better shooting effect. Since the photosensitive-element-setting-region BB of the present embodiment may include a plurality of first regions BB1 and a plurality of second regions BB2 (exemplified by 3 first regions BB1 and 2 second regions BB2 in fig. 4), the first regions BB1 and the second regions BB2 may be alternately arranged in a straight direction or an arc direction, and one second region BB2 is disposed between two adjacent first regions BB1 as shown in fig. 4, so that the first photosensitive elements 201 and the second photosensitive elements 202 may be alternately arranged at intervals, and the partial signal lines 101 of the display module 10 disposed in the second region BB2 may be distributed as uniformly as possible, so as to avoid that when a plurality of first regions BB1 are gathered together and a plurality of second regions BB2 are gathered together, the signal lines 101 not disposed in the first regions BB1 are all concentrated in the second regions BB 3, so that the routing lines around one first region BB1 adjacent to the second region BB2 are too large, and the routing lines are locally concentrated in the second regions BB 7377, furthermore, in the embodiment, when the photosensitive element arrangement area BB includes a plurality of first areas BB1 and a plurality of second areas BB2, the first areas BB1 and the second areas BB2 are alternately arranged, which is beneficial to achieving the effect of making the wiring of the second areas BB2 uniform, and is beneficial to improving the product yield.

The shapes of the first region BB1 and the second region BB2 may also be other various shapes (not shown in the drawings), such as a polygon (square, diamond, triangle), a regular polygon, a pentagram, and the like, and it only needs to be satisfied that one first region BB1 can be sufficient for disposing one first photosensitive element 201 and one second region BB2 can be sufficient for disposing one second photosensitive element 202, and the design shapes of the photosensitive element disposing region BB, the first region BB1, and the second region BB2 are not particularly limited in this embodiment.
