Display panel having camera and normal display sub-areas

1. A display panel, comprising:

a display area comprising a camera sub-area and a normal display sub-area;

wherein the display panel comprises:

a substrate, wherein a thickness of a region of the substrate corresponding to the camera sub-area is less than a thickness of a region of the substrate corresponding to the normal display sub-area;

a thin film transistor layer disposed on the substrate;

an organic light emitting layer disposed on the thin film transistor layer; and

an encapsulation layer disposed on the organic light emitting layer;

wherein a via hole is disposed in regions of the thin film transistor layer and the organic light emitting layer corresponding to the camera sub-area.

2. The display panel according to claim 1 , wherein the via hole is filled with a light transmissive material.

3. The display panel according to claim 1 , wherein a region of the substrate corresponding to the camera sub-area is provided with a recess, and an opening of the recess is disposed away from the thin film transistor layer.

4. The display panel according to claim 3 , wherein the recess comprises a bottom surface that is shaped as an arc and is concave to the substrate.

5. The display panel according to claim 1 , wherein the substrate is a flexible substrate composed of a polyimide material.

6. The display panel according to claim 1 , wherein the encapsulation layer is composed of at least one of silicon oxide, silicon nitride, silicon oxynitride, and amorphous silicon.

7. A display device, comprising the display panel according to claim 1 .
