Abstract

A display device includes a cover window including a curved portion, and a panel member laminated on the cover window. A method of manufacturing a display device includes mounting a cover window including a curved portion on a first jig including a curved portion, mounting a panel member on a second jig that conforms to a surface of the first jig, and laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig. An apparatus for manufacturing a display device includes a first jig including a mount surface that is partially curved to conform to a surface of a cover window, a second jig including a surface conforming to the mount surface and configured to contact a panel member, and a driving unit.

Claims (26)

1. A method of manufacturing a display device, the method comprising:

mounting a cover window comprising a curved portion on a first jig comprising a curved portion;

mounting a panel member comprising a display panel on a second jig that conforms to a surface of the first jig;

laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig, and

compressing the cover window and the panel member together with a load of greater than or equal to 0.3 MPa and less than or equal to 0.5 MPa,

wherein outer surfaces of the cover window and the first jig are curved surfaces each having a curvature radius or a curvature radius of a portion of the cover window is different from a curvature radius of another portion of the cover window, and a curvature radius of a portion of an outer surface of the first jig is different from a curvature radius of another portion of the outer surface of the first jig.

2. The method of claim 1 , wherein at least a portion of the panel member contacts a surface of the second jig.

3. The method of claim 1 , wherein the panel member is bent along an outer surface of the second jig during the mounting of the panel member on the second jig.

4. The method of claim 1 , wherein the panel member is smaller in at least one of a length or a width than the cover window.

5. The method of claim 1 , wherein

the panel member is flat during the mounting of the panel member on the second jig, and

the laminating of the cover window to the panel member comprises partially curving the panel member by the moving of the first one of the first jig or the second jig.

6. The method of claim 1 , wherein the first one of the first jig or the second jig is above the first other one of the first jig or the second jig, or the first other one of the first jig or the second jig is above the first one of the first jig or the second jig.

7. The method of claim 1 , wherein a second one of the first jig or the second jig is formed by protruding toward or recessing away from a second other one of the first jig or the second jig.

8. The method of claim 7 , wherein the second other one of the first jig or the second jig is formed by recessing away from or protruding toward the second one of the first jig or the second jig.

9. The method of claim 1 , wherein the mounting of the panel member comprises fixing the panel member to the second jig.

10. The method of claim 1 , wherein the panel member is flexible.

11. The method of claim 1 , wherein the panel member is attached to a recessed outer surface of the cover window or a protruding outer surface of the cover window.

12. The method of claim 1 , wherein the panel member further comprises a touch screen panel (TSP).

13. The method of claim 1 , wherein the cover window comprises a flat portion and the curved portion extended from the flat portion.

14. The method of claim 1 , wherein at least one of the first jig or the second jig comprises at least one of a cushion unit.

15. A method of manufacturing a display device, the method comprising:

mounting a cover window comprising a curved portion on a first jig comprising a curved portion;

mounting a display panel on a second jig that conforms to a surface of the first jig; and

laminating the cover window to the display panel by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig,

wherein outer surfaces of the cover window and the first jig are curved surfaces each having a curvature radius or a curvature radius of a portion of the cover window is different from a curvature radius of another portion of the cover window, and a curvature radius of a portion of an outer surface of the first jig is different from a curvature radius of another portion of the outer surface of the first jig.
