Abstract

A display module and the manufacturing method of the same, which are able to eliminate the attachment mark between the supporting assembly and the display panel, are provided. The display module includes a display panel; a supporting assembly, configured to support the display panel; an adhesive layer, configured to attach the supporting assembly to a non-display surface of the display panel; and an optical filter layer being on a side of the adhesive layer distal to the supporting assembly, and an orthographic projection of the optical filter layer on the supporting assembly covers an orthographic projection of the adhesive layer on the supporting assembly.

First claim

What is claimed is:

1. A display module, comprising:
a display panel;
a supporting assembly, configured to support the display panel;
an adhesive layer, configured to attach the supporting assembly to a non-display surface of the display panel; and
an optical filter layer being on a side of the adhesive layer distal to the supporting assembly, and an orthographic projection of the optical filter layer on the supporting assembly covers an orthographic projection of the adhesive layer on the supporting assembly,
wherein the optical filter layer comprises a quarter-wave plate and a polarizer, and the polarizer is on a side of the quarter-wave plate distal to the adhesive layer.

2. The display module of claim 1 , wherein the orthographic projection of the optical filter layer on the supporting assembly completely overlaps the orthographic projection of the adhesive layer on the supporting assembly.

3. The display module of claim 1 , wherein the optical filter layer is on the non-display surface of the display panel.

4. The display module of claim 3 , further comprising a transparent optical adhesive between the optical filter layer and the non-display surface of the display panel, wherein the transparent optical adhesive attaches the optical filter layer to the non-display surface of the display panel.

5. The display module of claim 4 , wherein the adhesive layer and the transparent optical adhesive both include optical clear adhesive.

6. The display module of claim 1 , further comprising a protective layer, wherein the protective layer is on a side of the display panel distal to the supporting assembly.

7. A display device, comprising the display module of claim 1 .

8. A manufacturing method of the display module of claim 1 , comprising:
attaching the supporting assembly to the non-display surface of the display panel by the adhesive layer; and
attaching the optical filter layer to the side of the adhesive layer distal to the supporting assembly such that the orthographic projection of the optical filter layer on the supporting assembly covers the orthographic projection of the adhesive layer on the supporting assembly.

9. The manufacturing method of the display module of claim 8 , wherein attaching the optical filter layer to the side of the adhesive layer distal to the supporting assembly comprises attaching the optical filter layer to the non-display surface of the display panel by a transparent optical adhesive.

10. The manufacturing method of the display module of claim 8 , wherein attaching the optical filter layer to the side of the adhesive layer distal to the supporting assembly comprises attaching the optical filter layer to the non-display surface of the display panel by roller attachment.
