Abstract

Claims (31)

1. A display device, comprising:

a backlight module;

a light modulation module configured to modulate light from the backlight module; and

a camera module comprising a lens assembly,

wherein the backlight module is disposed between the camera module and the light modulation module,

the backlight module comprises a first reflective element,

the first reflective element is arranged in accordance with arrangement of the lens assembly, and

a reflectance of the first reflective element for a visible band falls in a range of 35% to 95%, and a transmittance of the first reflective element for an infrared band is greater than 0%,

wherein the first reflective element has a plurality of first through holes, and a vertical projection area of each of the plurality of first through holes on an optical effective area of the lens assembly is not zero.

2. The display device according to claim 1 , wherein an aperture ratio of the first reflective element falls in a range of 30% to 60%.

3. The display device according to claim 1 , wherein an aperture ratio of the first reflective element falls in a range of 35% to 65%.

4. The display device according to claim 1 , wherein an aperture ratio of the first reflective element falls in a range of 48% to 52%.

5. The display device according to claim 1 , wherein the reflectance of the first reflective element for the visible band falls in a range of 35% to 65%.

6. The display device according to claim 1 , wherein the transmittance of the first reflective element for the infrared band falls in a range of 30% to 60%.

7. The display device according to claim 1 , wherein the backlight module further comprises a second reflective element,

the second reflective element has a plurality of second through holes, and

an aperture width of each of the plurality of second through holes is greater than an aperture width of each of the plurality of first through holes.

8. The display device according to claim 7 , wherein the first reflective element and the second reflective element are arranged in a same layer.

9. The display device according to claim 7 , wherein the backlight module further comprises a plurality of light-emitting elements, and

the plurality of light-emitting elements are arranged corresponding to the plurality of second through holes.

10. The display device according to claim 1 , wherein the backlight module further comprises at least one optical layer,

the at least one optical layer has an opening, and

the opening is arranged to overlap the first reflective element.

11. The display device according to claim 10 , wherein the backlight module further comprises a plurality of light-emitting elements, and

light emitted by the plurality of light-emitting elements is reflected by the at least one optical layer and then advances toward the first reflective element.

12. The display device according to claim 10 , wherein the backlight module further comprises a light guide plate, and

the first reflective element is disposed between the light guide plate and the lens assembly.

13. The display device according to claim 12 , wherein the light guide plate comprises an area corresponding to the first reflective element, and

the area has no through hole.

14. The display device according to claim 12 , wherein the backlight module further comprises a reflective layer, and

the reflective layer and the first reflective element are arranged in a same layer.
