Abstract

In a laminating apparatus and a method of manufacturing an organic light-emitting display, the laminating apparatus includes a heater which generates heat and the heating member which transfers heat received from the heater to a donor film. The heating member includes a first conducting layer which receives heat from the heater, a second conducting layer which is formed on the first conducting layer and which has a thermal conductivity different from that of the first conducting layer, and a third conducting layer which is formed on the second conducting layer and which has a thermal conductivity different from that of the second conducting layer.

First claim

What is claimed is:

1. A laminating apparatus for laminating a donor film, the apparatus comprising:
a heater which generates heat; and
a heating member which transfers heat received from the heater to the donor film, wherein the heating member comprises:
a first conducting layer which receives heat from the heater;
a second conducting layer which is disposed on the first conducting layer and which has a thermal conductivity different from a thermal conductivity of the first conducting layer; and
a third conducting layer which is disposed on the second conducting layer and which has a thermal conductivity different from a thermal conductivity of the second conducting layer.

2. The apparatus of claim 1 , wherein the first conducting layer comprises stainless steel.

3. The apparatus of claim 1 , wherein the second conducting layer comprises a heat insulating material.

4. The apparatus of claim 3 , wherein the heat insulating material is polyetheretherketone (PEEK).

5. The apparatus of claim 1 , wherein the third conducting layer comprises a heat insulating sheet.

6. The apparatus of claim 5 , wherein the heat insulating sheet is a Teflon sheet.

7. The apparatus of claim 1 , wherein the heating member is a quadrangle with a through hole.

8. The apparatus of claim 1 , wherein the heating member comprises a heating bar.

9. The apparatus of claim 1 , wherein the heating member comprises a heating roller.

10. A laminating apparatus for laminating a donor film, the apparatus comprising:
a heater generating heat; and
a plurality of heating members which are separated by a predetermined distance and which transfer heat received from the heater to the donor film,
wherein each of the heating members comprises:
a first conducting layer which receives heat from the heater;
a second conducting layer which is disposed on the first conducting layer and which has a thermal conductivity different from a thermal conductivity of the first conducting layer; and
a third conducting layer which is disposed on the second conducting layer and which has a thermal conductivity different from a thermal conductivity of the second conducting layer.

11. The apparatus of claim 10 , wherein the heating members comprise a first heating bar and a second heating bar which are separated from each other by a predetermined distance.

12. The apparatus of claim 11 , wherein the first heating bar and the second heating bar are bent in an ‘L’ shape, and inner sides of the first heating bar and the second heating bar face each other.

13. The apparatus of claim 11 , wherein the first heating bar and the second heating bar are disposed parallel to each other.

14. The apparatus of claim 13 , wherein the beating members further comprise a third heating bar and a fourth heating bar, the third heating bar and the fourth heating bar are separated from each other by a predetermined distance and are placed parallel with respect to each other, and the first heating bar and the second heating bar are disposed perpendicular to the third heating bar and the fourth heating bar.

15. A method of manufacturing an organic light-emitting display, the method comprising the steps of:
patterning a transfer layer of a donor film;
placing the donor film on an acceptor substrate which is disposed on a bottom film;
laminating the donor film;
transferring the transfer layer of the donor film to the acceptor substrate; and
removing the donor film from the acceptor substrate;
wherein the step of laminating the donor film comprises applying heat and pressure to the donor film using a heating member, wherein the heating member comprises:
a first conducting layer which receives heat from a heater;
a second conducting layer which overlaps the first conducting layer and which has a thermal conductivity different from a thermal conductivity of the first conducting layer; and
a third conducting layer which overlaps the second conducting layer and which has a thermal conductivity different from a thermal conductivity of the second conducting layer.

16. The method of claim 15 , wherein the heating member applies heat and pressure to a portion of the donor film which contacts the bottom film.

17. The method of claim 16 , wherein the heating member comprises a plurality of heating bars.

18. The method of claim 16 , wherein the heating member comprises a heating roller.

19. The method of claim 16 , wherein the heating member is a quadrangle with a through hole.

20. The method of claim 15 , wherein the first conducting layer comprises stainless steel.

21. The method of claim 15 , wherein the second conducting layer comprise a heat insulating material.

22. The method of claim 15 , wherein the heat insulating material is PEEK.

23. The method of claim 15 , wherein the third conducting layer is a heat insulating sheet.

24. The method of claim 23 , wherein the beat insulating sheet is a Teflon sheet.
