Abstract

A laminating apparatus and method are disclosed. The laminating device includes a first jig, a second jig facing the first jig, an auxiliary film fixing unit and a driving unit. A partially curved cover window is seated on the first jig. An auxiliary film and a panel member are seated on the second jig so as to be flat. The driving unit linearly moves at least one of the first and second jigs.

First claim

What is claimed is:

1. A laminating method comprising:
seating a cover window on a first jig, the cover window having at least one curved portion;
placing a panel member seated on an auxiliary film so as to be flat, the auxiliary film seated on a second jig facing the first jig;
linearly moving at least one of the first and second jigs to press the cover window and the panel member so as to laminate the cover window and the panel member with each other; and
separating the auxiliary film from the panel member after laminating the cover window and the panel member with each other.

2. The laminating method of claim 1 , wherein the auxiliary film and the panel member adhere to each other via an adhesive.

3. The laminating method of claim 1 , wherein the size of the cover window is greater than that of the display panel.

4. The laminating method of claim 1 , wherein a cushion unit is disposed on at least one of an outer surface of the first jig and an outer surface of the second jig.

5. The laminating method of claim 1 , wherein the linearly moving at least one of the first and second jigs comprises successively laminating the cover window and the panel member from central portions to both ends thereof.

6. The laminating method of claim 1 , wherein both ends of the auxiliary film are fixed to the auxiliary film fixing unit and disposed on the second jig.

7. The laminating method of claim 6 , wherein the auxiliary film fixing unit is linearly movable on a side of the second jig according to a linear motion of the at least one of the first jig and the second jig.

8. The laminating method of claim 1 , wherein the seating of the cover window on the first jig comprises fixing the cover window through a fixing unit disposed on the first jig.

9. The laminating method of claim 1 , wherein one of an outer surface of the first jig and an outer surface of the second jig protrudes, and wherein the other of the outer surface of the first jig and the outer surface of the second jig is recessed.

10. The laminating method of claim 1 , wherein the panel member comprises at least one of a touch screen panel and a display panel.

11. The laminating method of claim 1 , wherein the auxiliary film has opposing edge portions, and wherein the auxiliary film fixing unit contacts only the edge portions of the auxiliary film.

12. The laminating method of claim 1 , wherein the linearly moving further comprises moving the first and second jigs towards each other.

13. The laminating method of claim 1 , wherein the linearly moving comprises moving the first jig with a driving unit.

14. The laminating method of claim 13 , wherein the driving unit includes a pneumatic or hydraulic cylinder.

15. The laminating method of claim 13 , wherein, the driving unit includes a motor.
