Abstract

This application discloses a display device. The display device includes a display module, a frame surrounding the sides of the display module, a backlight module stacked with the display module, and a backplane. The frame includes holes. The backplane includes a main plane, side walls, and protrusions. The main plane is located on a side of the backlight module away from the display module. The side walls extend from the edges of the main plane toward the display module and are perpendicular to the main plane. The protrusions are located on the side walls and each of the protrusions is embedded in a corresponding one of the holes of the frame.

First claim

What is claimed is:

1. A display device, comprising:
a display module;
a frame surrounding sides of the display module, wherein the frame comprises holes;
a backlight module stacked with the display module; and
a backplane comprising a main plane, side walls and protrusions,
wherein the main plane is on a side of the backlight module away from the display module, the side walls extend from edges of the main plane towards the display module and are perpendicular to the main plane, the protrusions are on the side walls, and each of the protrusions is embedded in a corresponding one of the holes of the frame, and
wherein at least a part of the protrusions protrude from the side walls toward the display module in a direction perpendicular to the main plane of the backplane.

2. The display device according to claim 1 , wherein the display module comprises a liquid crystal display module.

3. The display device according to claim 1 ,
wherein the frame comprises width increasing regions protruding toward the display module, and
wherein at least a part of the holes are within the width increasing regions.

4. The display device according to claim 1 ,
wherein two adjacent ones of the side walls form an angle, and
wherein a distance between each of at least a part of the protrusions and the angle is less than or equal to 3 mm.

5. The display device according to claim 4 , wherein each of the two adjacent ones of the side walls is provided with at least one of the protrusions, the distance from which to the angle is less than or equal to 3 mm.

6. The display device according to claim 1 ,
wherein a shape of the protrusions comprises a strip, and
wherein a direction of a longest edge of the strip is same as a direction of a longest edge of the side wall where the strip is located.

7. The display device according to claim 1 , wherein at least a part of the holes are open-end holes.

8. The display device according to claim 1 , wherein at least a part of the holes are close-end holes.

9. The display device according to claim 1 , wherein a material of the backplane comprises aluminum.

10. The display device according to claim 9 , wherein the protrusions comprise bent protrusions.

11. The display device according to claim 1 , wherein a protrusion length of the protrusions from the side walls is less than or equal to a depth of the holes.

12. The display device according to claim 1 , wherein each of the side walls comprises an outer surface and an inner surface opposite to the outer surface, and at least a part of the protrusions protrude from the side walls in a direction from the outer surface to the inner surface.

13. The display device according to claim 1 , wherein the frame surrounds the side walls.

14. The display device according to claim 1 , further comprising:
a protective film covering the frame.

15. The display device according to claim 14 ,
wherein at least a part of the holes are open-end holes, and
wherein the protective film covers the open-end holes.

16. A display device, comprising:
a display module;
a frame surrounding sides of the display module, wherein the frame comprises holes;
a backlight module stacked with the display module; and
a backplane comprising a main plane, side walls and protrusions,
wherein the main plane is on a side of the backlight module away from the display module, the side walls extend from edges of the main plane towards the display module and are perpendicular to the main plane, the protrusions are on the side walls, and each of the protrusions is embedded in a corresponding one of the holes of the frame, and
wherein each of the side walls comprises an outer surface and an inner surface opposite to the outer surface, and at least a part of the protrusions protrude from the side walls in a direction from the outer surface to the inner surface.
