US 12,317,428 B2 · Display device, and method and apparatus for manufacturing the same

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.

Dependent claims

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.
