Abstract

A method of manufacturing a curved display device is disclosed. In one aspect, the method includes providing a frame, providing a flexible display panel and attaching a first area of the flexible display panel to the frame. The method also includes attaching a second area of the flexible display panel to the frame, wherein the providing of the flexible display panel comprises attaching a release paper to a surface of the flexible display panel, the release paper comprising first and second release areas respectively corresponding to the first and second areas of the flexible display panel. The method further includes removing the first release area from the flexible display panel before attaching the first area and removing the second release area from the flexible display panel before attaching the second area.

First claim

What is claimed is:

1. A method of manufacturing a curved display device, the method comprising:
providing a frame;
providing a flexible display panel that includes a driving circuit configured to generate an image;
attaching a first area of the flexible display panel to the frame by laminating;
attaching a second area of the flexible display panel to the frame by laminating, wherein the providing of the flexible display panel comprises attaching a release paper to a surface of the flexible display panel, the release paper comprising first and second release areas respectively corresponding to the first and second areas of the flexible display panel;
removing the first release area from the flexible display panel before attaching the first area; and
removing the second release area from the flexible display panel before attaching the second area,
wherein the first and second release areas are divided by a cutting line.

2. The method of claim 1 , wherein the providing of the frame comprises forming a first adhesive layer over the frame.

3. The method of claim 2 , wherein the providing of the flexible display panel comprises, before attaching the release paper, forming a second adhesive layer over the surface of the flexible display panel.

4. The method of claim 3 , wherein the flexible display panel is attached to the frame via the first and second adhesive layers.

5. The method of claim 1 , further comprising, before removing the first release area, attaching a fixing tape to the second area of the flexible display panel.

6. The method of claim 5 , wherein the fixing tape is attached to a portion of the frame outside the flexible display panel and fixes a location of the flexible display panel.

7. The method of claim 6 , wherein the fixing tape is parallel to the cutting line.

8. The method of claim 5 , further comprising, before removing the second release area, removing the fixing tape.

9. The method of claim 1 , wherein the frame comprises at least one curved portion that is convex toward the flexible display panel.

10. A method of manufacturing a curved display device, the method comprising:
providing a frame comprising at least one curved portion that is convex toward an external area;
attaching a release paper to a surface of a flexible display panel that includes a driving circuit configured to generate an image, the release paper comprising first and second release areas that are divided by a cutting line;
arranging the flexible display panel on the frame such that the release paper faces toward the frame;
attaching a fixing tape to the flexible display panel so as to fix a location of the flexible display panel;
removing the first release area;
attaching a first area of the flexible display panel to the frame by laminating;
removing the fixing tape and the second release area; and
attaching a second area of the flexible display panel to the frame by laminating.

11. The method of claim 10 , further comprising forming a first adhesive layer over the at least one curved portion.

12. The method of claim 11 , further comprising, before attaching the release paper, forming a second adhesive layer over the surface of the flexible display panel.

13. The method of claim 12 , wherein the flexible display panel is attached to the frame via the first and second adhesive layers.

14. The method of claim 10 , wherein the fixing tape is attached to the second area.

15. The method of claim 14 , wherein the fixing tape is attached to a portion of the frame outside the flexible display panel and fixes a location of the flexible display panel.

16. The method of claim 14 , wherein the fixing tape is parallel to the cutting line.

17. A method of manufacturing a curved display device, the method comprising:
providing a frame;
providing a flexible display panel that has first and second areas different from each other that do not overlap each other in the depth dimension of the curved display device, wherein the flexible display panel includes a driving circuit configured to generate an image;
attaching a release paper to a surface of the flexible display panel, the release paper comprising first and second release areas respectively corresponding to the first and second areas of the flexible display panel;
attaching the first and second areas to the frame by laminating;
removing the first release area from the flexible display panel before attaching the first area to the frame; and
removing the second release area from the flexible display panel before attaching the second area to the frame,
wherein the first and second release areas are divided by a cutting line.

18. The method of claim 17 , wherein the frame comprises at least one curved portion that is convex toward the flexible display panel.

19. The method of claim 17 , further comprising:
forming a first adhesive layer over the frame; and
forming a second adhesive layer over the surface of the flexible display panel, before attaching the release paper.

20. The method of claim 1 , wherein each of the first and second areas of the flexible display panel is configured to generate an image.

21. The method of claim 1 , wherein the first and second areas of the release paper are integrally formed such that the release paper is configured as a single release paper.
