Abstract

A laminating apparatus and method of fabricating a display device are provided. According to an exemplary embodiment of the present disclosure, the laminating apparatus includes a first jig, which is configured to fix a window having curved surfaces, and a second jig, which includes a pressure pad facing the first jig. The pressure pad includes a top surface, which is convex toward the first jig, and depressed portions, which are inwardly depressed from side surfaces, respectively.

Claims (28)

1. A method of fabricating a display device, comprising:

preparing a first jig, which fixes a window, a second jig, which includes a pressure pad facing the first jig and having a top surface that is convex and depressed portions that are inwardly depressed from side surfaces of the pressure pad, respectively, and a panel, which is disposed on the second jig;

gradually bonding the window and the panel by applying pressure to the panel with the pressure pad; and

pushing ends of the panel inwardly by stoppers such that the ends of the panel are located on inner sides of the depressed portions, respectively.

2. The method of claim 1 , further comprising:

gradually bonding the window and the panel by applying pressure to the panel with the pressure pad with ends of the window and the ends of the panel spaced apart from each other.

3. The method of claim 1 , further comprising:

bending the panel by pushing the ends of the panel inwardly with panel supports.

4. A method of fabricating a display device, comprising:

preparing a first jig, which fixes a window, a second jig, which includes a pressure pad facing the first jig and having a top surface that is convex toward the first jig and depressed portions that are inwardly depressed from side surfaces of the pressure pad, respectively, and a panel, which is disposed on the second jig;

gradually bonding the window and the panel by applying pressure to the panel with the pressure pad; and

locating stoppers between ends of the panel and ends of the window;

wherein the first jig includes a surface facing the second jig, the surface of the first jig including a flat surface and the curved surfaces, which are disposed at both sides of the flat surface,

wherein the stoppers include body portions, respectively, and hand portions, respectively, which extend from the body portions, and a coating layer disposed on each of the hand portions.

5. The method of claim 4 , further comprising: bending the panel by pushing the ends of the panel inwardly with panel supports.

6. The method of claim 4 , wherein the pressure pad further includes protruding portions, which are disposed on the outer sides of the side surfaces, respectively.

7. A method of fabricating a display device, comprising:

preparing a first jig, which fixes a window, a second jig, which includes a pressure pad facing the first jig and having a top surface that is convex toward the first jig and depressed portions that are inwardly depressed from side surfaces of the pressure pad, respectively, and a panel, which is disposed on the second jig;

gradually bonding the window and the panel by applying pressure to the panel with the pressure pad;

wherein the first jig includes a surface facing the second jig, and

wherein the surface of the first jig includes a flat surface and first, second, third, and fourth curved surfaces, which are disposed on the sides of the flat surface.

8. The method of claim 7 , wherein the depressed portions include depression lines, and the depression lines form a closed polygonal shape in a plan view.

9. The method of claim 7 , wherein the surface of the first jig further includes four connecting curved surfaces, which connect the first, second, third, and fourth curved surfaces.

10. The method of claim 9 , wherein the depressed portions are disposed at corners, respectively, of the pressure pad to correspond with the four connecting curved surfaces.

11. The method of claim 10 , further comprising:

locating first, second, third, and fourth stoppers adjacent to the four connecting curved surfaces.

12. The method of claim 7 , further comprising:

locating first, second, third, and fourth stoppers correspond with the first, second, third, and fourth curved surfaces, respectively.
