Abstract

Provided are laminating apparatus and method. A laminating apparatus includes a jig assembly, which includes the first jig and an elastic member, and a second jig. A laminating method includes placing a first plate on a jig assembly, placing a second plate on a second jig which is placed to face the first jig, bringing the second plate into contact with the adhesive layer by making the jig assembly and the second jig approach each other, and, attaching the first plate and the second plate to each other by making the jig assembly and the second jig approach closer to each other. The jig assembly includes a first jig and an elastic member which comprises a top portion and sloping portions sloping downward from the top portion. An adhesive layer is disposed between the first plate and the second plate.

First claim

What is claimed is:

1. A laminating apparatus, comprising:
a first jig;
an elastic member which is disposed on the first jig, a top surface of the elastic member comprising a top portion and sloping portions sloping downward from the top portion; and
a second jig which is separated from the first jig by a predetermined distance and faces the first jig, wherein the second jig comprises a flat surface which faces the first jig, and the second jig has bent portions at both edge sides thereof.

2. The laminating apparatus of claim 1 , wherein a thickness of the elastic member is uniform.

3. The laminating apparatus of claim 2 , wherein the first jig comprises a top portion and sloping portions that slope downward from the top portion, a thickness of the top portion of the first jig being different from the thicknesses of the sloping portions of the first jig.

4. The laminating apparatus of claim 1 , wherein a top surface of the first jig is flat, and the top portion of the elastic member has a different thickness from thicknesses of the sloping portions of the elastic member.

5. The laminating apparatus of claim 1 , wherein a bottom surface of the elastic member has the same shape as the top surface of the first jig.

6. The laminating apparatus of claim 1 , wherein the sloping portions are curved.

7. The laminating apparatus of claim 1 , further comprising a spring device which protrudes a predetermined distance from the top surface of the first jig, the elastic member being supported by the spring device.

8. A laminating method, comprising:
placing a first plate on a jig assembly that comprises a first jig and an elastic member which comprises a top portion and sloping portions sloping downward from the top portion;
placing a second plate on a second jig which is placed to face the first jig, an adhesive layer being disposed between the first plate and the second plate, wherein the second jig is separated from the first jig by a predetermined distance and faces the first jig, wherein the second jig comprises a flat surface which faces the first jig, and the second jig has bent portions at both edge sides thereof;
bringing the second plate into contact with the adhesive layer by making the jig assembly and the second jig approach each other; and
attaching the first plate and the second plate to each other by making the jig assembly and the second jig approach closer to each other in a state that the second plate and the adhesive layer are in the contact with each other.

9. The laminating method of claim 8 , wherein a contact area between the second plate and the adhesive layer increases gradually.

10. The laminating method of claim 9 , wherein as the contact area between the second plate and the adhesive layer increases gradually, the first plate applies pressure to the elastic member thereby to reduce a thickness of the top portion of the elastic member.

11. The laminating method of claim 8 , wherein the second plate has bent portions at both edge sides thereof.

12. The laminating method of claim 11 , wherein the first plate is a flexible panel, and the second plate is a window.
