Abstract

A method of manufacturing a display apparatus which displays high-quality images includes disposing a case on a lamination mold, disposing a display panel such that a first surface of the display panel faces a first surface of the case, and attaching the display panel on the case with a first adhesive layer between the first surface of the case and the first surface of the display panel, and pressing the display panel by a cap including an indented portion in a surface of the cap.

Claims (35)

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

disposing a case on a lamination mold;

disposing a display panel such that a first surface of the display panel faces a first surface of the case, and attaching the display panel on the case with a first adhesive layer between the first surface of the case and the first surface of the display panel; and

pressing the display panel by a cap including an indented portion in a surface of the cap facing the display panel.

2 . The method of claim 1 , wherein the display panel includes a central area and a corner area in a corner of the display panel, and

the attaching the display panel includes disposing the display panel such that the corner area corresponds to a corner of the case.

3 . The method of claim 2 , wherein the first surface of the case has a shape corresponding to the indented portion of the cap.

4 . The method of claim 2 , wherein the first surface of the case has a shape engaged with the indented portion of the cap.

5 . The method of claim 1 , wherein the case includes an elastic material.

6 . The method of claim 1 , wherein the case includes at least one of silicone, polycarbonate, and polyurethane.

7 . The method of claim 1 , wherein the attaching the display panel include disposing the cap such that a second surface of the display panel opposite to the first surface of the display panel faces the cap.

8 . The method of claim 7 , wherein the surface of the cap is non-adhesive processed.

9 . The method of claim 7 , wherein the surface of the cap is coated with fluorine-based compound.

10 . The method of claim 1 , wherein the attaching the display panel includes attaching a second adhesive layer to a second surface of the display panel opposite to the first surface of the display panel.

11 . The method of claim 10 , wherein the second adhesive layer includes at least one of a pressure sensitive adhesion, an optical clear adhesive, and an optical clear resin.

12 . The method of claim 10 , further comprising removing the cap from the display panel, disposing a cover window to face the second surface of the display panel, and coupling the display panel to the cover window through the second adhesive layer.

13 . The method of claim 1 , further comprising detaching the display panel from the case.

14 . The method of claim 13 , wherein the case includes an ultraviolet-transmissive material.

15 . The method of claim 13 , wherein the detaching of the display panel includes detaching the display panel from the case by irradiating an ultraviolet ray to the display panel in a direction of a second surface of the case opposite to the first surface of the case, and lowering adhesiveness of the first adhesive layer.

16 . A method of manufacturing a display apparatus, the method comprising:

disposing a case on a lamination mold, the case including a light-blocking layer;

disposing a display panel such that a first surface of the display panel faces a surface of the case, and attaching the display panel on the case with a first adhesive layer between the surface of the case and the first surface of the display panel; and

pressing the display panel by a cap including an indented portion in a surface of the cap facing the display panel.

17 . The method of claim 16 , wherein the display panel includes a central area and a corner area in a corner of the display panel, and

the attaching of the display panel includes disposing the display panel such that the corner area corresponds to a corner of the case.

18 . The method of claim 17 , wherein the surface of the case has a shape corresponding to the indented portion of the cap.

19 . The method of claim 17 , wherein the surface of the case has a shape engaged with the indented portion of the cap.

20 . The method of claim 16 , wherein the case includes an elastic material.

21 . The method of claim 16 , wherein the case includes at least one of silicone, polycarbonate, and polyurethane.

22 . The method of claim 16 , wherein the attaching of the display panel includes disposing the cap such that a second surface of the display panel opposite to the first surface of the display panel faces the cap.

23 . The method of claim 22 , wherein the surface of the cap is non-adhesive processed.

24 . The method of claim 22 , wherein the surface of the cap is coated with a fluorine-based compound.

25 . The method of claim 16 , wherein the attaching of the display panel includes attaching a second adhesive layer to a second surface of the display panel opposite to the first surface of the display panel.

26 . The method of claim 25 , wherein the second adhesive layer includes at least one of a pressure sensitive adhesion, an optical clear adhesive, and an optical clear resin.

27 . The method of claim 25 , wherein removing the cap from the display panel, disposing a cover window to face the second surface of the display panel, and coupling the display panel to the cover window through the second adhesive layer.
