The present embodiment further explains that in the direction Z perpendicular to the light emitting surface E of the display module 000, the area S2 of the transparent area 102 may be set to be equal to the area S1 of the sub-pixel 1011, and since the area of the transparent area 102 formed on the display panel 10 is too large, although the lighting effect (photographing effect) of the lighting assembly 40 can be improved, the area of the transparent area 102 may be too large, which may reduce the normal display effect of the screen, and conversely, the area of the transparent area 102 may be too small, which may reduce the lighting effect (photographing effect) of the lighting assembly 40, so the area of the transparent area 102 formed on the display panel 10 is not too large or too small, generally the same as the size level of each sub-pixel 1011 of the pixel area 101, that is, the area S2 of the transparent area 102 is equal to the area S1 of the sub-pixel 1011, which is beneficial to improve the lighting effect of the lighting assembly 40, and may not affect the display effect of the screen.
It should be noted that, in the present embodiment, the shape of the light-transmitting area 102 formed on the display panel 10 is not particularly limited, but since there are many wiring designs on the display panel 10, forming the light-transmitting area 102 in a regular pattern (such as a long bar shape) can facilitate the wiring design of other signal traces on the display panel 10.

If the light-transmitting areas 102 of the same display unit row 100H are on the same horizontal line, human eyes can easily recognize the light-transmitting areas during normal display, and further the normal display effect is easily affected, so the mosaic principle is adopted in this embodiment, and the arrangement of the display units 100 as shown in fig. 7 can avoid the influence of the arrangement of the light-transmitting areas 102 on the display effect.
The arrangement of the display unit 100 of the present embodiment is shown in fig. 7, and the working principle of the display module may be as follows: as shown in fig. 8, at this time, the pixel region 101 of the display panel 10 may be formed by injecting liquid crystal molecules between the thin film transistor array substrate and the color filter substrate of the display panel 10, and applying a driving voltage to the two substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light of the backlight module 20 to generate a picture, so that each first display region AA1 of the display module 000 normally displays a desired picture.

In the second working state (i.e. the lighting state) of the display module 000, the misalignment control structure can control the second film layer 30B to move (as the moving direction F indicated in the process from fig. 12 to fig. 13), so that the light-transmitting region 102 of the display panel 10, the through hole 201 of the backlight module 20, the hollow portion 30B1 on the second film layer 30B of the light supplementing and condensing assembly 30, and the light-condensing structure 302 on the first film layer 30A overlap each other in the forward projection to the light-emitting surface E of the display module 000, and therefore, no matter where the lighting assembly 40 is located below the backlight module 20, the ambient light can enter the light-condensing structure 302 through the light-transmitting region 102, the through hole 201, and the hollow portion 30B1 in sequence, and then is condensed to the lighting assembly 40 through the light-condensing structure 302 to complete the lighting operation.
