Since the functional layer 52 is disposed in the second region 22, light of the light supplement light source 51 can be conducted, and thus the position of the light supplement 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 supplement assembly 50 is arranged under the condition that the width of the frame of the display device 200 is not increased, so that light supplement is performed on the dark area on one side of the through hole 40.
In order to make the display device 200 have the light sensing elements with the front camera function, the through hole 40 is formed in the backlight module 30 to accommodate the front camera, that is, a hole is formed in the back plate of the backlight module 30 corresponding to the camera area, the back plate is stretched upwards along the edge of the hole to form a sidewall surrounding the through hole, and then the optical assembly is placed in the space of the back plate formed by the through hole 40. Fig. 2 only shows that the through hole 40 penetrates through the backlight module 30 and the display panel 10 along the second direction Y, but is not limited thereto, and the through hole 40 only penetrates through the backlight module 30 along the second direction Y, and the display panel 10 is not penetrated through by the through hole 40, so as to meet the requirement of a full-screen, and a penetrating film layer may be specifically arranged on the through hole 40 according to an actual situation, which is not described in detail below.
In some alternative embodiments, with reference to fig. 1 and fig. 2, in the display device 200 according to the present invention, the light provided by the fill-in light source 51 is totally reflected and propagates in the functional layer 52 along the first direction X.
It can be understood that, in the display device 200 provided in the embodiment of the present invention, by arranging the light provided by the light supplement light source 51 to be totally reflected and propagated in the functional layer 52 along the first direction X, it can be ensured that all the light provided by the light supplement light source 51 is incident into the light guide plate 31 through the functional layer 52, on one hand, the quantity of the light incident into the light guide plate 31 can be ensured, the luminance of the region C can be improved, the luminance of the region C can be unified with the luminance of other positions of the first region 21, so as to achieve the luminance uniformity of the display device 200, on the other hand, the light provided by the light supplement light source 51 is prevented from being refracted to the cover plate 20 through the functional layer 52 and being emitted out of the display device 200, which also can play a role in preventing the display device 200 from light leakage.
In some alternative embodiments, and with continued reference to fig. 1 and 2, embodiments of the present invention provide a display device 200 in which the functional layer 52 has a refractive index greater than the refractive index of the film layer adjacent thereto along the second direction Y.
It is understood that the display device 200 according to the embodiment of the present invention is configured such that the refractive index of the functional layer 52 along the second direction Y is greater than the refractive index of the adjacent film layer, for example, the functional layer 52 is located between a first film layer (not shown) and a second film layer (not shown) along the second direction Y, the first film layer is 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 is refracted away from the normal when entering the optically thinner medium from the optically denser medium, the refraction ray proceeds along the surface as the incident angle θ increases to a certain level, i.e., the refraction angle is 90 °, which is called the critical angle. If the incident angle is greater than the critical angle, there is no refraction, all light rays return to the optically dense medium, and the refractive index of the functional layer 52 is set to be greater than that of the first film layer, and the refractive index of the functional layer 52 is set to be greater than that of the second film layer, the functional layer 52 can be totally reflected at the interface with the first film layer, and the functional layer 52 can also be totally reflected at the interface with the second film layer, so that the light provided by the fill-in light source 51 can be transmitted in the functional layer 52, on one hand, the quantity of light rays entering the light guide plate 31 can be ensured, the brightness of the area C can be improved, the brightness of the area C can be unified with the brightness of other positions of the first area 21, the uniformity of the brightness of the display device 200 is realized, on the other hand, the light rays provided by the light supplement light source 51 are prevented from being refracted to the cover plate 20 through the functional layer 52, and emits the light out of the display device 200, i.e., can prevent the light leakage of the display device 200. In the display devices with different structures, all the adjacent film layers of the functional layer may be different, so that only the refractive index of the adjacent film layers is limited, and the function of the film layer is not specifically limited.
In some alternative embodiments, as shown in fig. 1 and 2, only the shape of the first virtual plane S in the orthographic projection of the cover plate 10 is illustrated in fig. 1. The display device 200 provided in the present embodiment: taking a first virtual plane S, wherein the first virtual plane S is parallel to the light emergent direction of the display panel 10 and is vertical to the first direction X; the orthographic projection of the light supplementing assembly 50 on the first virtual plane S and the orthographic 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 supplement assembly 50, the light supplement light source 51 in the light supplement assembly 50 provides light supplement light, the light supplement light irradiates the area C through the functional layer 52, and compensates the luminance of the area C, so as to achieve the luminance uniformity of the display device. If the orthographic projection of the light supplement component 50 on the first virtual plane S and the orthographic projection of the through hole 40 on the first virtual plane S are not overlapped, sufficient light supplement light cannot be irradiated into the area C, and the brightness of the area C cannot be effectively compensated, so that at least partial overlapping of the orthographic projection of the light supplement component 50 on the first virtual plane S and the orthographic projection of the through hole 40 on the first virtual plane S needs to be set, sufficient light supplement light is 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 kept consistent, and the brightness uniformity of the display device 200 is realized. The overlapping region of the orthographic projection of the light supplementing assembly 50 on the first virtual plane S and the orthographic projection of the through hole 40 on the first virtual plane S is not limited in the present invention, and the orthographic projection of the light supplementing assembly 50 on the first virtual plane S and the orthographic projection of the through hole 40 on the first virtual plane S may be overlapped, so as to ensure that all light supplementing light sources can be irradiated into the region C as much as possible, compensate the brightness of the region C, and achieve the brightness uniformity of the display device 200.
