Display module and display device

1. A display module used in a display device having a camera lens, comprising:

a display panel, wherein a camera hole is defined in a position of the display panel corresponding to the camera lens; and

a cover plate, wherein the cover plate is disposed on the display panel, a recess is defined in a surface of the cover plate facing the display panel to form a receiving hole, the receiving hole is disposed correspondingly to the camera hole, and a ring-shaped blocking layer is disposed in the receiving hole to block a periphery of the camera hole;

wherein a depth of a portion of the receiving hole covered by the ring-shaped blocking layer is greater than a thickness of the ring-shaped blocking layer, and a depth of another portion of the receiving hole not covered by the ring-shaped blocking layer is less than a thickness of the ring-shaped blocking layer, and

wherein a diameter of the receiving hole is greater than or equal to a diameter of the camera hole.

2. The display module of claim 1 , wherein the ring-shaped blocking layer is disposed in a circular-ring shaped arrangement on a bottom periphery of the receiving hole.

3. The display module of claim 2 , wherein an outer diameter of the ring-shaped blocking layer is greater than or equal to an internal diameter of the camera hole, and an internal diameter of the ring-shaped blocking layer is less than the internal diameter of the camera hole.

4. A display module used in a display device having a camera lens, comprising:

a display panel, wherein a camera hole is defined in a position of the display panel corresponding to the camera lens; and

a cover plate, wherein the cover plate is disposed on the display panel, a recess is defined in a surface of the cover plate facing the display panel to form a receiving hole, the receiving hole is disposed correspondingly to the camera hole, and a ring-shaped blocking layer is disposed in the receiving hole to block a periphery of the camera hole;

wherein a depth of a portion of the receiving hole covered by the ring-shaped blocking layer is greater than a thickness of the ring-shaped blocking layer, and a depth of another portion of the receiving hole not covered by the ring-shaped blocking layer is less than a thickness of the ring-shaped blocking layer.

5. The display module of claim 4 , wherein a diameter of the receiving hole is greater than or equal to a diameter of the camera hole.

6. The display module of claim 5 , wherein the ring-shaped blocking layer is disposed in a circular-ring shaped arrangement on a bottom periphery of the receiving hole.

7. The display module of claim 6 , wherein an outer diameter of the ring-shaped blocking layer is greater than or equal to an internal diameter of the camera hole, and an internal diameter of the ring-shaped blocking layer is less than the internal diameter of the camera hole.

8. The display module of claim 4 , wherein the receiving hole is a circular hole or a ring-shaped hole.

9. The display module of claim 4 , wherein the ring-shaped blocking layer is made of black ink.

10. The display module of claim 4 , wherein the display panel comprises a display layer and a polarizer layer which are stacked, and the camera hole passes and extends through the display layer and the polarizer layer.

11. The display module of claim 10 , wherein an optically clear adhesive layer is disposed between the polarizer layer and the cover plate.

12. The display module of claim 4 , wherein the cover plate comprises a transparent cover plate or a transparent flexible cover plate.

13. A display device, comprising:

a camera lens; and

a display module, wherein the display module comprises:

a display panel, wherein a camera hole is defined in a position of the display panel corresponding to the camera lens; and

a cover plate, wherein the cover plate is disposed on the display panel, a recess is defined in a surface of the cover plate facing the display panel to form a receiving hole, the receiving hole is disposed correspondingly to the camera hole, and a ring-shaped blocking layer is disposed in the receiving hole to block a periphery of the camera hole; wherein a depth of a portion of the receiving hole covered by the ring-shaped blocking layer is greater than a thickness of the ring-shaped blocking layer, and a depth of another portion of the receiving hole not covered by the ring-shaped blocking layer is less than a thickness of the ring-shaped blocking layer; and

wherein the camera lens is disposed on a side of the display panel away from the cover plate and is disposed correspondingly to the camera hole defined in the display panel.

14. The display module device of claim 13 , wherein a diameter of the receiving hole is greater than or equal to a diameter of the camera hole.

15. The display module device of claim 14 , wherein the ring-shaped blocking layer is disposed in a circular-ring shaped arrangement on a bottom periphery of the receiving hole.

16. The display module device of claim 15 , wherein an outer diameter of the ring-shaped blocking layer is greater than or equal to an internal diameter of the camera hole, and an internal diameter of the ring-shaped blocking layer is less than the internal diameter of the camera hole.

17. The display module device of claim 13 , wherein the ring-shaped blocking layer is made of black ink.

18. The display module device of claim 13 , wherein the display panel comprises a display layer and a polarizer layer which are stacked, and the camera hole passes and extends through the display layer and the polarizer layer.
