Description

Display device

Technical Field

The invention relates to the technical field of display, in particular to a display device.

Background

Along with the continuous development of display technology, the functions of the display panel are increased, and besides the picture display function, the display panel can further realize the camera shooting function, the fingerprint identification function and the like. For mobile display products (mobile phones or tablets) existing in the market, the camera function is one of the key considerations for consumers to select mobile display products.

At present, mobile terminals such as mobile phones, tablet computers and the like generally have front and rear cameras. In practical photographing use, the front camera and the rear camera are respectively biased, that is, the camera module generally comprises a front camera module and a rear camera module, and in order to ensure the photographing effect, the camera module is provided with a plurality of cameras. The current installation modes of the camera unit for most display products generally comprise a rear-loading mode and a front-loading mode. The post-assembly means that the prepared display screen and the camera unit are installed in a split mode, and the prepared display screen and the camera unit are connected through a data line so as to complete the assembly of the camera unit and the display screen; if the design of the front camera and the rear camera in the existing vehicle-mounted display screen is just the rear-mounted type, the front camera in the rear-mounted type design can be of a lifting type structure, and the rear camera is a vehicle recorder. The front-loading type is to dig holes in a part of the structure of the display screen, such as a backlight assembly, to place photosensitive devices, such as a camera unit, in the manufacturing process of the display screen, namely, a common under-screen camera design.

However, the peripheral camera with the current post-assembly design is particularly cumbersome to use, and the whole structure is thicker and occupies a large space. The front-loading 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 wind the perforated area, so that the wiring around the perforated area is likely to be dense, and short circuit is caused, and if short circuit is to be avoided, the frame around the perforated area is difficult to compress.

Therefore, the display device which can be compatible with the front camera and the rear camera, is beneficial to reducing the wiring density around the camera, and compresses the peripheral frame of the open area as much as possible is a technical problem to be solved by the person skilled in the art.

Disclosure of Invention

In view of this, the invention provides a display device to solve the problems of complicated post-assembly design, troublesome use, large occupied space, and difficult compression of the frame of a short-circuit hole digging area caused by dense wiring around the hole digging area due to the pre-assembly design, which is not well compatible with the front-assembly camera and the rear-assembly camera in the prior art.

The invention discloses a display device, which comprises a first display area and a photosensitive element setting area, wherein the first display area and the photosensitive element setting area are adjacently arranged; the photosensitive element setting area comprises a first area and a second area, and the transmittance of the first area is larger than that of the second area; the display device comprises a display module and a photosensitive element, wherein the photosensitive element comprises a first photosensitive element and a second photosensitive element, the photosensitive surface of the first photosensitive element faces the light-emitting surface of the display module, and the photosensitive surface of the second photosensitive element faces away from the light-emitting surface of the display module; the first photosensitive element is positioned in the first area, and the second photosensitive element is positioned in the second area; the display module comprises a plurality of signal lines, and at least part of the signal lines are positioned in the second area.

Compared with the prior art, the display device provided by the invention has the advantages that at least the following beneficial effects are realized:

Because the light sensitive surface of the first photosensitive element faces the light emitting surface of the display module, in order to ensure that the first photosensitive element can work normally, the light sensitive surface of the first photosensitive element faces the light emitting surface of the display module and meanwhile information in the environment needs to be acquired, the transmittance of the first area is larger than that of the second area, the identification performance of the first photosensitive element can be improved, and the transmittance of the first area is prevented from influencing the accuracy of the first photosensitive element. The display module comprises a plurality of signal wires, and the signal wires can be wires for transmitting electric signals required by realizing the display function of the display module. Because the second photosensitive element is located in the second area of the photosensitive element setting area, the photosensitive surface of the second photosensitive element deviates from the light-emitting surface of the display module, namely, compared with the first photosensitive element, the second photosensitive element has less light demand on the light-emitting surface of the display module, and the photosensitive surface of the second photosensitive element can work normally even if deviating from the light-emitting surface of the display module. Therefore, at least part of the signal wires in the display module are arranged in the second area, so that the available space of the photosensitive element arrangement area can be fully utilized, at least part of the signal wires which do not influence the work of the second photosensitive element are arranged in the second area, the wiring pressure around the photosensitive element arrangement area can be effectively shared, the size of a wiring frame around the photosensitive element arrangement area can be effectively compressed, the display device can be compatible with a front camera and a rear camera, the wiring density around the photosensitive element arrangement area can be reduced, the frame around the photosensitive element arrangement area can be reduced, more display space can be provided for the first display area, and the screen occupation ratio can be improved.

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 BB2.

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 may be understood as an area of the display device 000 for normal display, and the display module 10 of the first display area AA1 may be provided with a structure for implementing a display function, such as a driving transistor, a color resistor, and other structures, which are not described herein, and the setting may be specifically performed with reference to the type of the display module 10 in the related art. The photosensitive element setting area BB is used for setting the photosensitive element 20, and optionally, the photosensitive element 20 may be a recognition element such as a camera, a light sensor, a distance sensor, a biosensor, etc., and the embodiment is only exemplified by taking the photosensitive element 20 as a camera. The first display area AA1 and the photosensitive element setting area BB of the present embodiment are disposed adjacently, and the photosensitive element setting area BB may be located in an edge area of the entire first display area AA1, that is, the photosensitive element setting area is disposed adjacently to the first display area AA1 (not illustrated in the drawings), or the first display area AA1 may also be disposed partially around the photosensitive element setting area BB, for example, the first display area AA1 is an area including a notch in which the photosensitive element setting area BB is disposed (similar to "Liu Haibing", not illustrated in the drawings); alternatively, as shown in fig. 1, the first display area AA1 may also be disposed entirely around the photosensitive element disposition area BB, and the relative positional relationship between the first display area AA1 and the photosensitive element disposition area BB is not specifically limited in this embodiment, and may be selectively disposed according to actual needs during implementation.

The photosensitive element setting area BB of the present 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, the 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 faces 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 setting area BB can be understood as a setting area of the rear camera. Since the light sensing surface 201A of the first photosensitive 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 photosensitive element 201 needs to face the light emitting surface 10E of the display module 10 (the front surface of the display device 000) and meanwhile, information in the environment needs to be collected (such as ambient light, when the first photosensitive element 201 is another light sensor, a distance sensor or a biosensor, and other structural information in the environment needs to be collected), the transmittance of the first area BB1 is greater than the transmittance of the second area BB2, so that the recognition performance of the first photosensitive element 201 can be improved, and the transmittance of the first area BB1 is prevented from affecting the accuracy of the first photosensitive element 201.

The display module 10 of the present 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, which is not particularly limited, and only the signal lines 101 need to be understood as wires for transmitting electrical signals required for implementing the display function of the display module 10. Because the second photosensitive element 202 is located in the second area BB2 of the photosensitive element setting area BB, the photosensitive surface 202A of the second photosensitive element 202 faces away from the light emitting surface 10E of the display module 10, that is, the second photosensitive element 202 has less light demand on the light emitting surface 10E of the display module 10 compared with the first photosensitive element 201, the photosensitive surface 202A of the second photosensitive element 202 can normally work even if facing away from the light emitting surface 10E of the display module 10, therefore, at least part of the signal lines 101 in the display module 10 are located in the second area BB2, thereby fully utilizing the available space of the photosensitive element setting area BB, setting at least part of the signal lines 101 which do not affect the operation of the second photosensitive element 202 in the second area BB2, effectively sharing the wiring pressure around the photosensitive element setting area BB, being beneficial to compressing the size of the wiring frame around the photosensitive element setting area BB as much as possible, so that the display device 000 is compatible with the front camera and the rear camera, reducing the wiring density around the photosensitive element setting area BB, being beneficial to reducing the wiring frame around the photosensitive element setting area BB, being beneficial to reducing the setting area AA more occupying more space around the first display area BB than the first area BB.

Alternatively, at least a portion of the signal lines 101 in the display module 10 are disposed in the second area BB2 in the present embodiment, and it may be understood that a portion of the plurality of signal lines 101 in the display module 10 are disposed in the second area BB2 (not shown in the drawings), which is not limited herein, and may be disposed according to a specific wiring structure of the signal lines 101 in specific implementation.

It should be understood that the number of photosensitive elements 20 is only shown in the drawings of the present embodiment, and in particular, the number of the first photosensitive elements 201 and the second photosensitive elements 202 disposed in the photosensitive element disposition area BB may be selectively disposed according to actual requirements. The present embodiment is merely illustrative of the shape of the photosensitive element 20, and the shape of the photosensitive element 20 may be, for example, but not limited to, a shape according to practical requirements.

It can be further understood that in fig. 1, in order to clearly illustrate the setting position of the photosensitive element 20, when the display module 10 is subjected to transparency filling, in particular implementation, when viewing angle of fig. 1, that is, the light emitting surface 10E of the display module 10, each photosensitive element 20 may not be seen, that is, the photosensitive elements 20 may be disposed on one side of the backlight surface of the display module 10 (a side facing away from the light emitting surface 10E of the display module 10, such as a position illustrated in a cross-sectional view of fig. 2), at this time, 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, and then the display module 10 may perform some transmittance improvement on the first area BB1, such as adopting a structure of a high light transmittance material, avoiding setting the structure of a light-impermeable material in the area, etc., which is not described herein.

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 integrated structure of the display panel and the backlight module, and may be configured according to a specific type of the display device 000 when being implemented. Fig. 1 to 3 of the present embodiment are only exemplary structures of the display device 000, including but not limited to, for example, the first display area AA1 used as a normal display area, and the display module 10 may further include other structures capable of realizing a display function, etc., and in specific implementation, the structures of the display device in the related art may be referred to for understanding, and the description of the present embodiment is omitted herein.

Because the photosensitive element setting area BB set in this embodiment may include a plurality of first areas BB1 and a plurality of second areas BB2 (in fig. 4, 3 first areas BB1 and 2 second areas BB2 are exemplified), the first areas BB1 and the second areas BB2 may be alternately arranged along a straight line direction or a direction with an arc, and as a second area BB2 is set between two adjacent first areas BB1 shown in fig. 4, so that the first photosensitive elements 201 and the second photosensitive elements 202 may be alternately set at intervals, and part of the signal lines 101 of the display module 10 set in the second areas BB2 may be distributed as uniformly as possible, so that when a plurality of first areas BB1 are gathered together and a plurality of second areas BB2 are gathered together, the signal lines 101 not set in the first areas BB1 are all concentrated in the second areas BB2, so that the number of windings around the first areas BB1 adjacent to the second areas BB2 is too large, and local wiring is dense, and further when the first areas BB1 and the second areas BB2 are alternately set, the second areas BB2 are alternately arranged, so that the first areas BB1 and the second areas BB2 are better are arranged, and the product is better.

Alternatively, the photosensitive element setting region BB of the present embodiment may be elliptical as shown in fig. 4, and the first region BB1 and the second region BB2 may be circular as shown in fig. 4, including but not limited to this shape when embodied. The larger photosensitive element setting area BB may have other elongated shapes (not shown) such as a crescent shape, a fan shape, etc., and it is only necessary to satisfy that the photosensitive element setting area BB may be sufficient to set at least one first photosensitive element 201 and at least one second photosensitive element 202. The shapes of the first area BB1 and the second area BB2 may be other shapes (not shown in the drawings), such as polygons (square, diamond, triangle), regular polygons, pentahedron shapes, etc., and it is only necessary to satisfy that one first area BB1 may be enough to provide one first photosensitive element 201, one second area BB2 may be enough to provide one second photosensitive element 202, and the design shapes of the photosensitive element providing areas BB, the first area BB1, and the second area BB2 are not particularly limited in this embodiment.
