Abstract

The present application provides a display panel and a display device. The display panel includes a frame. The frame includes a light-facing portion and a backlight portion, wherein the backlight portion faces a light-shielding region and is provided as a light to guide the lights emitted from the side light source toward the frame to the light-shielding region. The backlight portion of the frame is provided as a light guide to guide the lights to the light-shielding region to improve the brightness of the light-shielding region on the display screen, so that the overall brightness of the display screen is more uniform and the display effect is improved.

Claims (29)

1. A display panel, comprising:

a display screen, wherein the display screen has two main surfaces opposite to each other and a side surface connected between the two main surfaces, the display screen is provided with a receiving hole, and the receiving hole is perpendicular to the main surface axially;

a side light source mounted on a side surface of the display screen; and

a frame disposed around the receiving hole, and an outer peripheral wall of the frame being in direct contact with an inner peripheral wall of the receiving hole;

wherein the display screen has a light-shielding region in which the side light source is shielded by the frame, the frame includes a light-facing portion facing the side light source and a backlight portion facing the light-shielding region, and the backlight portion is provided as a light guide to guide the lights emitted from the side light source toward the frame to the light-shielding region.

2. The display panel of claim 1 , wherein the light-facing portion and the backlight portion are light guides, and lights emitted from the side light source are irradiated to the light-facing portion and are guided to the backlight portion along a circumferential direction of the frame.

3. The display panel of claim 1 , wherein the light-facing portion comprises a first reflecting layer and a first light guide portion, the first reflecting layer is disposed on an inner peripheral surface of the first light guide portion, the backlight portion comprises a second reflecting layer and a second light guide portion, and the second reflecting layer is disposed on an inner peripheral surface of the second light guide portion.

4. The display panel of claim 3 , wherein the first reflecting layer and the second reflecting layer are white polyimide coatings.

5. The display panel of claim 3 , wherein the display panel further comprises a first condenser prism disposed on a surface of the first reflecting layer facing the first light guide portion and a second condenser prism disposed on a surface of the second reflecting layer facing the second light guide portion.

6. The display panel of claim 5 , wherein a number of the first condenser prisms is plural, and a plurality of the first condenser prisms are arranged along a circumferential direction of the first reflecting layer, a number of the second condenser prisms is plural, and a plurality of the second condenser prisms are arranged along a circumferential direction of the second reflecting layer.

7. The display panel of claim 1 , wherein the side light source is mounted at an end of a longitudinal side of the display screen, and the receiving hole is close to another end of the longitudinal side of the display screen.

8. The display panel of claim 1 , wherein the light-facing portion is integrally molded with the backlight portion.

9. The display panel of claim 1 , wherein the receiving hole is provided as a circular hole or an elliptical hole, and the frame has a shape corresponding to the receiving hole.

10. A display device, comprising a control panel, a camera unit, and a display panel, wherein the camera unit is mounted in a receiving hole of the display panel, and the control panel is electrically connected to the display panel and the camera unit;

wherein the display panel, comprising:

a display screen, wherein the display screen has two main surfaces opposite to each other and a side surface connected between the two main surfaces, the display screen is provided with a receiving hole, and the receiving hole is perpendicular to the main surface axially;

a side light source mounted on a side surface of the display screen; and

a frame disposed around the receiving hole, and an outer peripheral wall of the frame being in direct contact with an inner peripheral wall of the receiving hole;

wherein the display screen has a light-shielding region in which the side light source is shielded by the frame, the frame includes a light-facing portion facing the side light source and a backlight portion facing the light-shielding region, and the backlight portion is provided as a light guide to guide the lights emitted from the side light source toward the frame to the light-shielding region.

11. The display device of claim 10 , wherein the light-facing portion and the backlight portion are light guides, and lights emitted from the side light source are irradiated to the light-facing portion and are guided to the backlight portion along a circumferential direction of the frame.

12. The display device of claim 10 , wherein the light-facing portion comprises a first reflecting layer and a first light guide portion, the first reflecting layer is disposed on an inner peripheral surface of the first light guide portion, the backlight portion comprises a second reflecting layer and a second light guide portion, and the second reflecting layer is disposed on an inner peripheral surface of the second light guide portion.

13. The display device of claim 12 , wherein the first reflecting layer and the second reflecting layer are white polyimide coatings.

14. The display device of claim 12 , wherein the display panel further comprises a first condenser prism disposed on a surface of the first reflecting layer facing the first light guide portion and a second condenser prism disposed on a surface of the second reflecting layer facing the second light guide portion.

15. The display device of claim 14 , wherein a number of the first condenser prisms is plural, and a plurality of the first condenser prisms are arranged along a circumferential direction of the first reflecting layer, a number of the second condenser prisms is plural, and a plurality of the second condenser prisms are arranged along a circumferential direction of the second reflecting layer.

16. The display device of claim 10 , wherein the side light source is mounted at an end of a longitudinal side of the display screen, and the receiving hole is close to another end of the longitudinal side of the display screen.

17. The display device of claim 10 , wherein the light-facing portion is integrally molded with the backlight portion.

18. The display device of claim 10 , wherein the receiving hole is provided as a circular hole or an elliptical hole, and the frame has a shape corresponding to the receiving hole.

19. The display device of claim 10 , wherein an inner diameter of the frame is adapted to an outer diameter of a cross-sectional dimension of the camera unit mounted in the receiving hole.

20. The display device of claim 10 , wherein a radius of the receiving hole is equal to a sum of a radius of the camera unit and a thickness of the frame.
