Referring to fig. 1 to 3, the display device 10 includes: a display panel 120, a first backlight module 130, a second backlight module 140, and an off-screen camera 150; the first backlight module 130 is located at one side of the display panel 120, and an opening 133 is disposed in a region corresponding to the under-screen camera 150; the under-screen camera 150 is located in the opening 133, and the under-screen camera 150 realizes front shooting of the display device 10 according to light rays emitted from the outside; the second backlight module 140 is disposed on the base 151 of the off-screen camera 150, and the second backlight module 140 provides a light source for normal display of the second display area AA2 corresponding to the off-screen camera 150 and the display panel 120.

The display device 10 may include a housing 110, a display panel 120, a backlight module, and the like, wherein the display panel 120 and the backlight module are installed in the housing 110, and the backlight module is located on a side of the display panel 120 away from a light emitting surface of the display device.

In fig. 2, the under-screen camera 150 is only described for convenience and is not completely drawn into the opening 133, and in fact, when the depth of the opening 133 is relatively large, the under-screen camera 150 can be completely accommodated, and when the depth of the opening 133 is not enough to completely accommodate the under-screen camera 150, the remaining portion of the under-screen camera 150 that is not accommodated by the opening 133 can protrude from the surface of the first backlight module 130 away from the display panel 120.

Specifically, the light emitting member 141 serves to emit light, and the refracting member 142 serves to adjust the direction in which the light travels. When the light emitting element 141 is disposed on the inner wall 1510 of the base 151, most of the light emitted by the light emitting element 141 propagates toward the image pickup element 152, and the light folding element 142 is disposed between the image pickup element 152 and the inner wall 1510, and particularly between the light emitting element 141 and the image pickup element 152, so that the light folding element 142 can adjust the light propagating toward the image pickup element 152 to be incident into the display panel 120, and particularly into the second display area AA2 corresponding to the display panel 120 and the off-screen camera 150, thereby ensuring that the second display area AA2 corresponding to the display panel 120 and the off-screen camera 150 receives the light required for normal display.

The relative position relationship between the second display area AA2 and the first display area AA1 may be that part of the edge of the second display area AA2 is adjacent to the first display area AA1, or all the edges are adjacent to the first display area AA1, as long as the two are adjacent to each other, so that when the two are displayed simultaneously, a complete display screen can be formed, and fig. 1 exemplarily illustrates that all the edges of the second display area AA2 are adjacent to the first display area AA 1.

The first subpixel 12010 and the second subpixel 120201 may be formed of a filter. Normally, a black matrix is disposed between two adjacent sub-pixels, and in this embodiment, a black matrix is disposed between two adjacent first sub-pixels 12010 and between two adjacent second sub-pixels 120201. The area of the second sub-pixel 120201 in the second display area AA2 is larger than the area of the first sub-pixel 12010 in the first display area AA1, so that the area of the black matrix between two adjacent second sub-pixels 120201 in the second display area AA2 is smaller than the area of the black matrix between two adjacent first sub-pixels 12010 in the first display area AA1 (that is, when the first display area AA1 and the second display area AA2 are areas of the same size, the total area of the black matrix in the second display area AA2 is smaller than the total area of the black matrix in the first display area AA 1), so that the light transmittance of the second display area AA2 is larger than the light transmittance of the first display area AA1, which is beneficial for the operation of the off-screen camera 150, more external light is incident to the off-screen camera 150, and is specifically incident to the camera element 152 of the off-screen camera 150, that sufficient external light can be acquired when the off-screen camera 150 is taking a picture.

The area of the second region 12021 may be equal to the area of the second subpixel 120201, or may be larger than the area of the second subpixel 120201; compared with the area of the second region 12021 equal to the area of the second sub-pixel 120201, if the area of the second region 12021 is larger than the area of the second sub-pixel 120201, more external light is incident to the off-screen camera 150 when the off-screen camera 150 works, and the specific incident light is incident to the camera element 152 of the off-screen camera 150, so that the off-screen camera 150 can obtain enough external light when shooting, and the shooting effect of the off-screen camera 150 is ensured.

When the off-screen camera 150 is in an operating state, it indicates that the off-screen camera 150 is shooting, at this time, the second backlight module 140 may be turned off, the second backlight module 140 does not provide light sources for the second sub-pixels 120201 and the second region 12021, and external light enters the camera 152 of the off-screen camera 150 through the second region 12021 and the second sub-pixels 120201. In this embodiment, when the second backlight module 140 is turned off, since the second backlight module 140 does not provide backlight to the second sub-pixel 120201 and the second region 12021, the external light may not only be incident to the under-screen camera 150 through the second region 12021, but also be incident to the under-screen camera 150 through the second sub-pixel 120201, so that the overall light transmittance of the second pixel 1202 is relatively high, and thus the under-screen camera 150 receives sufficient external light to realize the shooting of the display device, and the display device can realize a good shooting effect.

When the display panel 120 displays a full screen, the second backlight module 140 may be turned on to provide light to the second sub-pixel 120201 because the second backlight module 140 needs to provide light to the second sub-pixel 120201. The second backlight module 140 may provide light to the second sub-pixel 120201 and provide light to the second region 12021.

In one embodiment of the present invention, optionally, with continued reference to fig. 15, the second subpixel 120201 includes a red subpixel R, a green subpixel G, and a blue subpixel B; along the first direction x, the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B are sequentially arranged in a cycle, the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B in the same second pixel 1202 form a sub-pixel unit, and the sub-pixel unit and the second region 12021 are alternately arranged; along the second direction y, the light emitting colors of the second sub-pixels 120201 are the same; the first direction x is perpendicular to the second direction y, the first direction is a row direction of the pixel array, and the second direction is a column direction of the pixel array.

Specifically, the red, green, and blue sub-pixels R, G, and B may be formed by a red filter, a green filter, and a blue filter, respectively, and in some embodiments, the second region 12021 includes a white sub-pixel W that is not provided with a filter but may retain a liquid crystal layer in the display panel. The pixel arrangement mode of the second display area AA2 forms a pixel arrangement mode of RGBW cyclic arrangement along the first direction, and this arrangement mode can make the white sub-pixel W more concentrated, which is beneficial to the transmission of external light, thereby ensuring a good shooting effect of the under-screen camera 150; and the first sub-pixel 12010 may also include a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In addition, the second sub-pixel 120201 may include a white sub-pixel, a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, so as to further improve the light transmittance of the second display area AA2, and make the off-screen camera 150 have a better shooting effect. Of course, the second display area AA2 may be designed to have other pixel arrangements based on similar design considerations, which is not specifically limited in this embodiment.
