Abstract

Claims (15)

1 . A display module, comprising a display region and a non-display region, and comprising:

a substrate comprising a display section and an extending section that are arranged oppositely, and a bending section that is bent to connect the display section and the extending section and is located in the non-display region;

a display function layer disposed on a side of the display section away from the extending section and located in the display region;

a support layer disposed on a side of the substrate away from the display function layer, and comprising a first support layer and a second support layer, wherein a side of the extending section close to the display section is provided with the first support layer, and a side of the display section close to the extending section is provided with the second support layer;

a buffer layer disposed between the first support layer and the second support layer; and

a first adhesive layer disposed on the first support layer and between the first support layer and the buffer layer,

wherein a distance from an end of the first adhesive layer away from the non-display region to the non-display region is greater than a distance from an end of the first support layer away from the non-display region to the non-display region.

2 . The display module according to claim 1 , wherein a projection of the first adhesive layer in a direction perpendicular to a surface of the buffer layer facing the first adhesive layer covers a projection of the first support layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer.

3 . The display module according to claim 2 , wherein the projection of the first adhesive layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer is coincident with the projection of the first support layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer.

4 . The display module according to claim 1 , wherein material of the first adhesive layer comprises a pressure sensitive adhesive.

5 . The display module according to claim 1 , wherein a second adhesive layer is arranged between the second support layer and the buffer layer, and a projection of the second adhesive layer in a direction perpendicular to a surface of the buffer layer facing the first adhesive layer covers at least a projection of the second support layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer.

6 . The display module according to claim 5 , wherein the projection of the second adhesive layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer overlaps with the projection of the second support layer in the direction perpendicular to the surface of the buffer layer facing the first adhesive layer.

7 . The display module according to claim 1 , wherein the display module further comprises a strained adhesive layer, the strained adhesive layer is arranged on a side of the substrate away from the support layer, and the strained adhesive layer covers at least the bending section.

8 . The display module according to claim 1 , wherein a material of the first adhesive layer comprises a pressure sensitive adhesive or a foam adhesive.

9 . The display module according to claim 1 , wherein a material the buffer layer comprises stainless steel, a foam cushion, or a polyimide film.
