Abstract

Claims (38)

1. A display panel, comprising:

a display module having a display face and a non-display face opposite to the display face;

at least one color layer disposed at a side of the display module away from the display face; and

a light absorption layer disposed at a side of the at least one color layer away from the display module, a first through hole being defined in the light absorption layer;

wherein a second through hole is defined in the at least one color layer, the second through hole is located corresponding to and in communication with the first through hole, and the first through hole and the second through hole are located corresponding to an external functional module;

wherein a reflectivity of the at least one color layer is larger than or equal to 50%.

2. The display panel of claim 1 , wherein the at least one color layer comprises an orange layer, a white layer, a gray layer, or any combination thereof.

3. The display panel of claim 1 , wherein the at least one color layer comprises a plurality of orange layers stacked with each other.

4. The display panel of claim 1 , wherein the at least one color layer comprises at least one orange layer and at least one white layer stacked with each other.

5. The display panel of claim 4 , wherein the at least one white layer is located between the at least one orange layer and the light absorption layer.

6. The display panel of claim 1 , further comprising:

a transparent substrate disposed between the display module and the light absorption layer;

wherein the at least one color layer is disposed on a surface of the transparent substrate, a third through hole is defined in the transparent substrate, and the third through hole is located corresponding to and in communication with the first through hole and the second through hole.

7. The display panel of claim 1 , further comprising:

a metal layer disposed between the light absorption layer and the at least one color layer;

wherein a fourth through hole is defined in the metal layer, and the fourth through hole is located corresponding to, and in communication with, the first through hole and the second through hole.

8. The display panel of claim 7 , wherein the metal layer is a copper foil.

9. The display panel of claim 1 , further comprising a scattering layer disposed between the display module and the at least one color layer.

10. The display panel of claim 9 , wherein the scattering layer comprises scattering particles dispersed therein; and

wherein the scattering particles are selected from the group consisting of organosilicon particles, polyethylene particles, acrylic resin particles, nano-barium sulfate particles, silicon dioxide particles, calcium carbonate particles, and any combination thereof.

11. The display panel of claim 9 , wherein the scattering layer is an integral layer without any hole.

12. The display panel of claim 1 , wherein cross-sectional sizes of the first through hole and the second through hole are equal to each other; and

wherein projections of the first through hole and the second through hole on the display module coincide with each other.

13. The display panel of claim 1 , wherein a thickness of the at least one color layer is smaller than or equal to 10 μm.

14. The display panel of claim 1 , comprising:

a composite layer; and a support layer disposed between the display module and the composite layer to support the display module; wherein the at least one color layer is a portion of the composite layer or a portion of the support layer, or a layer separated from the composite layer and the support layer.

15. A display device, comprising a display panel, the display panel comprising:

a display module having a display face and a non-display face opposite to the display face;

at least one color layer disposed at a side of the display module away from the display face; and

a light absorption layer disposed at a side of the at least one color layer away from the display module, a first through hole being defined in the light absorption layer;

wherein a second through hole is defined in the at least one color layer, the second through hole is located corresponding to and in communication with the first through hole, and the first through hole and the second through hole are located corresponding to an external functional module;

wherein a reflectivity of the at least one color layer is larger than or equal to 50%.

16. The display device of claim 15 , further comprising:

a cover plate disposed at a side of the display module adjacent to the display face and the external functional module disposed at the side of the display module away from the display face and disposed corresponding to the first through hole and the second through hole.

17. The display device of claim 16 , wherein the cover plate comprises a flat region and a curved region adjacent to the flat region, and the first through hole, the second through hole, and the external functional module is in the flat region of the cover plate.

18. The display device of claim 16 , wherein the cover plate comprises a flat region and a curved region adjacent to the flat region, and the first through hole, the second through hole, and the external functional module is in the curved region of the cover plate.

19. The display device of claim 16 , wherein the cover plate is attached to the display module of the display panel.

20. The display device of claim 16 , wherein external functional module is the optical fingerprint identification sensor.
