Abstract

Claims (29)

1 . A display module, comprising:

a display panel comprising a display area and a non-display area surrounding the display area;

an optical adhesive layer, wherein the optical adhesive layer is on a light-emitting side of the display panel and covers the display area;

a cover plate, wherein the cover plate is on a side of the optical adhesive layer facing away from the display panel and covers the display panel and the optical adhesive layer;

wherein a side of the cover plate facing the optical adhesive layer is provided with a limiting groove for preventing an edge of the optical adhesive layer from overflowing, and at least the edge of the optical adhesive layer is in the limiting groove;

a polarizer, wherein the polarizer is between the display panel and the optical adhesive layer, and an edge of the polarizer is flush with an edge of the display panel;

a ground layer, and

a conductive medium in at least one position;

wherein the ground layer is on a side of the display panel facing away from the polarizer;

the conductive medium is coated on a side face of the display panel, and extends to contact with: a side of the cover plate facing the display panel, the edge of the polarizer and a side face of the ground layer; and

the optical adhesive layer comprises:

a main body part covering the display area of the display panel; and

at least one extension part connected with an edge of the main body part;

wherein the at least one extension part is arranged in one-to-one correspondence with the conductive medium in at least one position; and

the extension part is filled between corresponding conductive medium and the main body part.

2 . The display module according to claim 1 , wherein the limiting groove is a groove opposite to the optical adhesive layer, and the optical adhesive layer is in the groove.

3 . The display module according to claim 2 , wherein a depth of the groove is less than or equal to a thickness of the optical adhesive layer.

4 . The display module according to claim 2 , wherein a shape of an area enclosed by side walls of the groove matches the edge of the optical adhesive layer.

5 . The display module according to claim 1 , wherein the limiting groove is an annular groove surrounding the edge of the optical adhesive layer, and the edge of the optical adhesive layer is in the annular groove.

6 . The display module according to claim 1 , wherein an assembly gap is arranged between the edge of the optical adhesive layer and side walls of the limiting groove.

7 . The display module according to claim 6 , wherein a width of the assembly gap ranges from 0.08 mm to 0.2 mm.

8 . The display module according to claim 1 , wherein an edge of the extension part far away from the main body part is flush with the edge of the display panel.

9 . The display module according to claim 1 , wherein a side face of the extension part far away from the main body part is a concave-convex face.

10 . The display module according to claim 1 , wherein an orthographic projection of the extension part on the display panel is in a rectangular, trapezoidal or semi-elliptical shape.

11 . The display module according to claim 1 , wherein a shape of the main body part of the optical adhesive layer is rectangular, and at least a long side of the main body part is connected with the extension part.

12 . A display device, comprising the display module according to claim 1 .

13 . The display module according to claim 11 , wherein two long sides of the main body part are connected with the extension parts.

14 . The display module according to claim 13 , wherein the extension parts connected to the two long sides of the main body part are arranged oppositely.

15 . The display module according to claim 11 , wherein at least a short side of the main body part is connected with the extension part.
