In the display device of the related art, a backlight hole is required to be formed in a backlight module of the display device for placing a camera or a bio-sensing device. However, due to the design of forming the backlight hole in the backlight module, the light source cannot directly irradiate at the position facing the light source, and a dark area is inevitably formed in a certain area, so that the brightness of the area corresponding to the backlight hole is darker than that of other display areas in the display process, and the brightness of the display device is uneven. In order to solve the problem of uneven brightness of the display device, a light-compensating light source needs to be added, but the width of the frame of the display device is increased due to the arrangement of the light-compensating light source, which affects the narrow frame of the display device.
In order to solve the technical problems, the invention provides a display device. The display device according to the present invention will be described in detail below.

Fig. 1 illustrates only a part of the elements of the display device 200 for clarity of illustrating the positional relationship between the light supplementing module 50 and the through hole 40, and a specific film layer of the display device 200 may be illustrated in conjunction with fig. 2.

In the first direction X, the light compensating component 50 is located at a side of the through hole 40 away from the backlight source 32, which is not limited to the light compensating component 50 shown in fig. 2 being located directly above the through hole 40 away from the backlight source 32, but also may be located at sides of the through hole 40 on left and right sides, so long as the light compensating component 50 is located in an area range of the side of the through hole 40 away from the backlight source 32, which compensates brightness of a dark area, and the brightness uniformity of the display device is achieved in the protection range of the present invention; and the orthographic projection of the light supplementing component 50 on the plane where the cover plate 20 is located in the second area 22, along the first direction X, the light supplementing light source 51 is located at one side of the functional layer 52 away from the light guiding plate 31, so long as the light supplementing light source 51 and the functional layer 52 are located in the second area 22, under the condition that the frame width of the display device 200 is not increased, the light supplementing in a dark area at one side of the through hole 40 can be realized, whether the light supplementing light source 51 is located at the edge of the second area 22 away from the first area 21 is not limited, and the invention can adjust according to the position of the actual components of the second area 22, which is not repeated herein.
It can be understood that the display device 200 provided in this embodiment includes the through hole 40, and the backlight 32 is located on a side of the through hole 40 away from the first frame 11 along the first direction X, so that the light in the region C on the side of the through hole 40 away from the backlight 32 cannot enter, and a dark area is formed, which results in uneven brightness of the display device 200. Further, the display device 200 includes a light supplementing component 50, along the first direction X, the light supplementing component 50 is located on a side, away from the backlight source 32, of the through hole 40, the light supplementing component 50 includes a light supplementing light source 51 and a functional layer 52, along the first direction X, the light supplementing light source 51 is located on a side, away from the light guiding plate 31, of the functional layer 52, light provided by the light supplementing light source 51 propagates in the functional layer 52 along the first direction X, and is injected into the light guiding plate 31 to provide light for the region C, so as to compensate the brightness of the region C, and ensure the brightness uniformity of the display device 200. In the second area 22 where the cover 20 and the display panel 10 do not overlap, the package structure or the micro device of the display device 200 is generally placed, so that the light compensating component 50 can be disposed in the second area 22 corresponding to the through hole 40 along the first direction X, and thus, the light compensating component is not placed with a new frame width. Since the functional layer 52 is disposed in the second region 22, the light of the light-compensating light source 51 can be conducted, so that the position of the light-compensating light source 51 can be flexibly selected without affecting the arrangement and setting of the devices in the original second region 22. Based on the above principle, the light supplementing assembly 50 is disposed without increasing the frame width of the display device 200, so as to implement light supplementing in a dark area at one side of the through hole 40.
In order to provide the display device 200 with the light sensing element such as the front-end camera function, the through hole 40 may be formed on the backlight module 30 to accommodate the front-end camera, that is, the back plate of the backlight module 30 is hollowed out corresponding to the camera shooting area, and the back plate is stretched upwards along the edge of the hole to form a sidewall surrounding the through hole, and then the optical component is placed in the back plate space formed by the through hole 40. In fig. 2, only the through holes 40 penetrate the backlight module 30 and the display panel 10 along the second direction Y, but not limited thereto, and the through holes 40 only penetrate the backlight module 30 along the second direction Y, and the display panel 10 is not penetrated by the through holes 40, so as to meet the requirements of the overall screen, and the specific through holes 40 can be provided with penetrating film layers according to practical situations, which will not be described herein.
In some alternative implementations, continuing to refer to fig. 1 and 2, the display device 200 provided by the embodiment of the present invention includes light provided by the light-compensating light source 51 propagating in the functional layer 52 along the total reflection of the first direction X.
It can be appreciated that, in the display device 200 provided by the embodiment of the present invention, by arranging the light provided by the light-compensating light source 51 to be totally reflected and transmitted along the first direction X in the functional layer 52, it can be ensured that all the light provided by the light-compensating light source 51 is injected into the light guide plate 31 through the functional layer 52, on one hand, the number of the light injected into the light guide plate 31 can be ensured, the brightness of the area C can be improved, and the brightness of the area C can be unified with the brightness at other positions of the first area 21, so as to realize the brightness uniformity of the display device 200, and on the other hand, the light provided by the light-compensating light source 51 is prevented from being refracted to the cover plate 20 through the functional layer 52 and is injected out of the display device 200, so as to play a role in preventing the light leakage of the display device 200.
In some alternative embodiments, and as further shown in fig. 1 and 2, the display device 200 provided in the embodiment of the present invention has a refractive index of the functional layer 52 greater than that of the film layer adjacent thereto along the second direction Y.
It will be appreciated that in the display device 200 provided in this embodiment of the present invention, the refractive index of the functional layer 52 is greater than the refractive index of the adjacent film layers along the second direction Y, for example, the functional layer 52 is located between the first film layer (not shown in the figure) and the second film layer (not shown in the figure) along the second direction Y, the first film layer is located on the side close to the cover plate, the refractive index of the functional layer 52 is defined to be greater than the refractive index of the first film layer, and the refractive index of the functional layer 52 is greater than the refractive index of the second film layer. Since light enters the optically sparse medium from an optically dense medium, it is refracted away from the normal, when the angle of incidence θ, which is called critical angle, increases to a certain point, the refraction line proceeds along the surface, i.e., the angle of refraction is 90 °. If the incident angle is larger than the critical angle, no refraction is performed, all light rays return to the light-tight medium, the refractive index of the limiting functional layer 52 is larger than that of the first film layer, the refractive index of the functional layer 52 is larger than that of the second film layer, the functional layer 52 can be subjected to total reflection at the interface with the first film layer, the interface between the functional layer 52 and the second film layer is also subjected to total reflection, the light rays provided by the light supplementing light source 51 can be transmitted in the functional layer 52, on one hand, the quantity of the light rays injected into the light guide plate 31 can be ensured, the brightness of the area C can be improved, the brightness uniformity of the display device 200 can be realized, and on the other hand, the light rays provided by the light supplementing light source 51 are prevented from being refracted to the cover plate 20 through the functional layer 52 and are emitted out of the display device 200, so that the light leakage of the display device 200 can be prevented. In the display devices having different structures, the adjacent layers of the functional layer may be different, and thus, only the refractive index of the adjacent layers is limited, and the functions of the layers are not particularly limited.
In some alternative embodiments, as further shown in connection with fig. 1 and 2, only the shape of the orthographic projection of the first virtual plane S on the plane of the cover plate 10 is illustrated in fig. 1. The display device 200 provided in this embodiment: taking a first virtual plane S, wherein the first virtual plane S is parallel to the light emitting direction of the display panel 10, and the first virtual plane S is perpendicular to the first direction X; the front projection of the light supplementing assembly 50 on the first virtual plane S and the front projection of the through hole 40 on the first virtual plane S at least partially overlap.
It can be understood that the display device 200 provided in this embodiment includes the light compensating component 50, the light compensating light source 51 in the light compensating component 50 provides the light compensating light, and the light compensating light irradiates the region C through the functional layer 52 to compensate the brightness of the region C, so as to realize the brightness uniformity of the display device. If the front projection of the light compensating assembly 50 on the first virtual plane S and the front projection of the through hole 40 on the first virtual plane S do not overlap, the sufficient light compensating light cannot be irradiated into the area C, and the brightness of the area C cannot be effectively compensated, so that the front projection of the light compensating assembly 50 on the first virtual plane S and the front projection of the through hole 40 on the first virtual plane S at least partially overlap, the sufficient light compensating light is ensured to be irradiated into the area C, the brightness of the area C is effectively improved, the brightness of the area C and the brightness of the first area 21 at other positions can be ensured to be consistent, and the brightness uniformity of the display device 200 is realized. The present invention does not limit the overlapping area of the front projection of the light compensating component 50 on the first virtual plane S and the front projection of the through hole 40 on the first virtual plane S, and may also set the front projection of the light compensating component 50 on the first virtual plane S and the front projection of the through hole 40 on the first virtual plane S to overlap, so as to ensure that all the light compensating sources can irradiate into the area C as much as possible, compensate the brightness of the area C, and realize the brightness uniformity of the display device 200.
In some alternative embodiments, as shown in fig. 3 and fig. 4, fig. 3 is a schematic structural diagram of still another display device provided by an embodiment of the present invention, and fig. 4 is a cross-sectional view taken along the direction M-M' in fig. 3.
