Abstract

A terminal includes: an image acquisition module, a display panel, a light-emitting element, and a light converging member. An image acquisition module includes a lens. A light transmitting hole corresponding to the lens is formed in the display panel. The light-emitting element and the light converging member are arranged at the light transmitting hole. The light converging member is arranged on a side of the light-emitting element from which light is emitted, and is used for converging the light emitted by the light-emitting element over the lens.

First claim

The invention claimed is:

an image acquisition module comprising a lens;
a display panel, wherein a light transmitting hole corresponding to the lens is formed inside the display panel; and
a light-emitting element and a light converging member arranged at the light transmitting hole,
wherein the light converging member is arranged at a light-emitting side of the light-emitting element, and is positioned and structured to first converge the light emitted by the light-emitting element over the lens, and then uniformly project the converged light onto an area of the display panel corresponding to the light-transmitting hole.

2. The terminal of claim 1 , wherein the light converging member is disposed within the light transmitting hole, and is connected to a sidewall of the light transmitting hole; or
the light converging member is disposed over the light-emitting element.

3. The terminal of claim 2 , wherein the light-emitting element is disposed within the light transmitting hole, and is connected to a sidewall of the light transmitting hole; or
the light-emitting element is disposed in an area around the light transmitting hole underneath the display panel; or
the light-emitting element is movably disposed underneath the light transmitting hole and above the lens, and a moving range of the light-emitting element is from a field of view of the lens to an outside of the field of view of the lens.

4. The terminal of claim 2 , wherein the light converging member is formed with a first hollow region corresponding to the lens.

5. The terminal of claim 4 , wherein the light-emitting element is formed with a second hollow region corresponding to the first hollow region, and
an overlapping portion of the first hollow region and the second hollow region is arranged corresponding to the lens.

6. The terminal of claim 1 , wherein the light-emitting element is transparent.

7. The terminal of claim 1 , wherein the light-emitting element comprises at least one of: a light-emitting array element, or an independent light-emitting device.

8. The terminal of claim 1 , wherein the light-emitting element comprises a side light-emitting element having a distance from the lens greater than a first predetermined distance, and a field of view of the side light-emitting element is inclined toward a center of a field of view of the light-emitting element.

9. The terminal of claim 1 , wherein the light transmitting hole comprises: a first through hole formed on a backlight layer of the display panel and a second through hole formed on a filter layer of the display panel and corresponding to the first through hole.

10. The terminal of claim 9 , wherein
the display panel comprises an array substrate having a plurality of driving circuits; and
the plurality of driving circuits at the area of the display panel corresponding to the light transmitting hole have a density lower than a density at an area outside the light transmitting hole.

11. The terminal of claim 9 , wherein the light transmitting hole further comprises a third through hole formed in the array substrate and a liquid crystal layer of the display panel, and the third through hole communicates with the first through hole and the second through hole.

12. The terminal of claim 9 , further comprising: a light shading member arranged on a sidewall of the first through hole and used for shading a light emitted by the backlight layer.

13. A display panel, comprising:
a display screen formed with a light transmitting hole; and
a light-emitting element and a light converging member arranged at the light transmitting hole;
wherein the light converging member is located at a light-emitting side of the light-emitting element, and is positioned and structured to first converge the light emitted by the light-emitting element to a center of the light transmitting hole, and then uniformly project the converged light onto an area of the display panel corresponding to the light-transmitting hole.

14. The display panel of claim 13 , wherein the light converging member is disposed in the light transmitting hole, and the light converging member is connected to a sidewall of the light transmitting hole; or
the light converging member overlies on the light-emitting element.

15. The display panel of claim 14 , wherein the light-emitting element is disposed in the light transmitting hole, and is connected to a sidewall of the light transmitting hole; or
the light-emitting element is disposed in an area around the light transmitting hole under the display screen; or
the light-emitting element is movably disposed below the light transmitting hole, and a moving range of the light-emitting element is from the light transmitting hole to an outside of the light transmitting hole.

16. The display panel of claim 14 , wherein the light converging member is formed with a first hollow region arranged corresponding to a lens in an image acquisition module; and the light-emitting element is formed with a second hollow region disposed corresponding to the first hollow region.

17. The display panel of claim 13 , wherein the light-emitting element comprises a side light-emitting element having a distance to a sidewall of the light transmitting hole less than a second predetermined distance, and a field of view of the side light-emitting element is inclined toward a center of a field of view of the light-emitting element.

18. The display panel of claim 13 , wherein the light transmitting hole comprises: a first through hole formed on a backlight layer, and a second through hole formed on a filter layer and corresponding to the first through hole; and a density of driving circuit of a portion of an array substrate corresponding to the light transmitting hole is lower than a density of driving circuit of a portion of the array substrate corresponding to an outside of the light transmitting hole.

19. A display control method for controlling a display panel of a terminal including
an image acquisition module having a lens:
a display panel, wherein a light transmitting hole corresponding to the lens is formed inside the display panel; and
a light-emitting element and a light converging member arranged at the light transmitting hole,
wherein the light converging member is arranged at a light-emitting side of the light-emitting element, and is positioned and structured to first converge the light emitted by the light-emitting element over the lens, and then uniformly project the converged light onto an area of the display panel corresponding to the light-transmitting hole;
