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 (17)

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

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

mounting a panel member comprising a display panel on a second jig comprising a curved portion that corresponds to the curved portion of the first jig and comprising a flat portion that faces and corresponds to the flat portion of the first jig, wherein the curved portion of the cover window extends further than an end of the display panel in a horizontal direction; and

laminating the flat portion of the cover window to the panel member by moving one of the first jig or the second jig to another one of the first jig or the second jig, such that the curved portion of the cover window is spaced apart from an entire surface of the panel member to which the cover window is laminated.

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 one of the first jig or the second jig.

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

7. The method of claim 1 , wherein the first jig or the second jig is configured to protrude toward or recess away from the second jig or the first jig, respectively.

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

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

10. The method of claim 1 , wherein outer surfaces of the cover window and the first jig are curved surfaces each having a curvature radius.

11. The method of claim 1 , wherein 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.

12. 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.

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