Abstract

The present disclosure is related to a display device. The display device includes a middle frame, a display panel and a supporting member. The middle frame is provided with a first mating surface. The display panel includes a display substrate and a cover plate. A first notch is provided at a side of an edge of the cover plate close to the first mating surface. The first notch extends along a thickness direction of the cover plate. An orthographic projection of the display substrate on the cover plate at least partially overlaps an orthographic projection of the first mating surface on the cover plate. The supporting member includes a first supporting section and a second supporting section, the first supporting section is connected to the first mating surface, and the second supporting section is partially arranged in the first notch.

First claim

What is claimed is:

1. A display device, comprising:
a middle frame provided with a first mating surface;
a display panel comprising a display substrate and a cover plate arranged on a side of the display substrate, wherein a first notch is provided at a side of an edge of the cover plate close to the first mating surface, the first notch extends along a thickness direction of the cover plate, and an orthographic projection of the display substrate on the cover plate at least partially overlaps an orthographic projection of the first mating surface on the cover plate; and
a supporting member comprising a first supporting section and a second supporting section which are connected sequentially, wherein the first supporting section is connected to the first mating surface, and the second supporting section is partially arranged in the first notch;
wherein a second notch is provided at a side of the first notch, the second notch extends perpendicular to a thickness direction of the cover plate, and the supporting member further comprises a third supporting section which is connected to an end away from the first supporting section, and the third supporting section is snap-fitted in the second notch; and
wherein a third notch is provided at a second mating surface, and the supporting member further comprises a fourth supporting section, and the fourth supporting section is snap-fitted in the third notch.

2. The display device according to claim 1 , wherein the middle frame further comprises the second mating surface, and a gap is formed between a side surface of the first notch and the second mating surface, and the second supporting section is partly arranged in the gap, and a thickness of the second supporting section is equal to a width of the gap.

3. The display device according to claim 1 , wherein the first supporting section is spaced apart from the display substrate.

4. The display device according to claim 3 , wherein the display substrate has a display region and a binding region located at a periphery of the display region, and the orthographic projection of the first mating surface on the cover plate at least partially overlaps an orthographic projection of the binding region on the cover plate.

5. The display device according to claim 4 , wherein a width of the first supporting section is greater than or equal to a width of the first mating surface, and the orthographic projection of the binding region on the cover plate is located in an orthographic projection of the first supporting section on the cover plate.

6. The display device according to claim 1 , wherein a width of the third supporting section is smaller than a width of the first supporting section.

7. The display device according to claim 1 , wherein:
the middle frame is provided with an installation notch, the cover plate is arranged in the installation notch, and the first mating surface is an end surface of the installation notch; and
the middle frame further comprises the second mating surface, the second mating surface is a side surface of the installation notch, and the first notch and the second notch are arranged at a position of the side surface of the cover plate which is opposite to the second mating surface.

8. The display device according to claim 1 , wherein the supporting member is attached to a side surface of the first notch and divided into at least two parts along an extending direction of the side surface.

9. The display device according to claim 1 , wherein a flexible buffer layer is provided between the third supporting section and the second notch.

10. The display device according to claim 1 , wherein the supporting member is made of stainless steel.

11. The display device according to claim 1 , wherein the second notch extends continuously along an extending direction of an edge of the cover plate.

12. The display device according to claim 1 , wherein the second notch comprises a plurality of recesses, and the plurality of recesses are distributed at intervals along the extending direction of the side surface of the cover plate.

13. The display device according to claim 1 , wherein the edge of the cover plate is arc-shaped, and a height of the edge of the cover plate away from the first mating surface is gradually decreased from an end close to a center of the cover plate to an end away from the center.

14. The display device according to claim 1 , wherein the first supporting section is adhered to the first mating surface.

15. The display device according to claim 1 , wherein the third notch and the second notch are located in a same straight line.

16. The display device according to claim 1 , wherein a limiting portion is arranged on the middle frame to prevent the display panel from moving along a direction away from the first mating surface.
