Abstract

The present disclosure proposes a display module, a manufacturing method, and an electronic device. The display module includes a display panel, a polarizing layer on the display panel, a cover layer on the polarizing layer, and an adhesive layer between the polarizing layer and the cover layer. The adhesive layer is a viscosity-releasing adhesive layer.

First claim

What is claimed is:

1. A display module, comprising: a display panel; a polarizing layer, arranged on the display panel; a cover layer, arranged on the polarizing layer; and an adhesive layer, arranged directly between the polarizing layer and the cover layer; wherein the adhesive layer is a viscosity-releasing adhesive layer, wherein the cover layer comprises: a hard layer; and a filter layer sandwiched between the hard layer and the adhesive layer; wherein the display panel comprises a light-emitting device layer of which an orthographic projection on the filter layer is arranged in the filter layer.

2. The display module of claim 1 , wherein the adhesive layer is an ultraviolet (UV) viscosity-releasing optical adhesive.

3. The display module of claim 1 , wherein an area of the filter layer is greater than an area of a light-emitting region of the display module.

4. The display module of claim 1 , wherein the cover layer further comprises a light-shielding layer; the light-shielding layer is arranged on the hard layer and at both sides of the filter layer;
a sum of an area of the light-shielding layer and an area of the filter layer is equal to an area of the hard layer.

5. The display module of claim 4 , wherein a material for the light-shielding layer comprise ink.

6. A method of manufacturing a display module, comprising:
providing a display panel;
forming a polarizing layer on the display panel;
forming an adhesive layer on the polarizing layer;
forming a cover layer on the adhesive layer;
wherein the adhesive layer is a viscosity-releasing adhesive layer,
wherein the step of forming the cover layer on the adhesive layer comprises:
providing a hard layer;
forming a filter layer on the hard layer;
forming a light-shielding layer at both sides of the filter layer;
bonding the filter layer to the polarizing layer with the adhesive layer;
wherein a sum of the area of the light-shielding layer and the area of the filter layer is equal to the area of the hard layer.

7. The method of claim 6 , wherein the adhesive layer is an ultraviolet (UV) viscosity-releasing optical adhesive.

8. The method of claim 6 , wherein an area of the filter layer is greater than an area of a light-emitting region of the display module.

9. The method of claim 6 , wherein the display panel comprises a light-emitting device layer of which an orthographic projection on the filter layer is arranged in the filter layer.

10. The method of claim 9 , wherein a material for the light-shielding layer comprise ink.

11. The method of claim 6 , wherein the filter layer is an ultraviolet (UV) filter layer.

12. An electronic device comprising a display module, the display module comprising: a display panel; a polarizing layer, arranged on the display panel; a cover layer, arranged on the polarizing layer; and an adhesive layer, arranged directly between the polarizing layer and the cover layer; wherein the adhesive layer is a viscosity-releasing adhesive layer, wherein the cover layer comprises: a hard layer; and a filter layer sandwiched between the hard layer and the adhesive layer; wherein the display panel comprises a light-emitting device layer of which an orthographic projection on the filter layer is arranged in the filter layer.

13. The electronic device of claim 12 , wherein the adhesive layer is an ultraviolet (UV) viscosity-releasing optical adhesive.

14. The electronic device of claim 12 , wherein an area of the filter layer is greater than an area of a light-emitting region of the display module.

15. The electronic device of claim 12 , wherein the cover layer further comprises a light-shielding layer; the light-shielding layer is arranged on the hard layer and at both sides of the filter layer;
a sum of an area of the light-shielding layer and an area of the filter layer is equal to an area of the hard layer.

16. The electronic device of claim 15 , wherein a material for the light-shielding layer comprise ink.

17. The electronic device of claim 12 , wherein the filter layer is an ultraviolet (UV) filter layer.
