Method of manufacturing organic light-emitting display apparatus

1. A method of manufacturing an organic light-emitting display apparatus according to a laser-induced thermal imaging (LITI) method, the method comprising:

patterning a transfer layer of a donor film, the patterning comprising removing a non-pattern portion of the transfer layer whereby a pattern portion of the transfer layer remains;

disposing the donor film on an acceptor substrate;

laminating the donor film on the acceptor substrate;

transferring the pattern portion of the transfer layer of the donor film to the acceptor substrate; and

removing the donor film from the acceptor substrate,

wherein the patterning is performed before the disposing the donor film on the acceptor substrate.

2. The method of claim 1 , wherein the patterning comprises removing the non-pattern portion of the transfer layer using a laser.

3. The method of claim 2 , further comprising, before the patterning:

disposing the donor film on a supporting plate; and

aiming the laser with respect to a first alignment mark arranged on the supporting plate.

4. The method of claim 3 , further comprising aligning a second alignment mark arranged on the supporting plate and a third alignment mark arranged on the acceptor substrate.

5. The method of claim 4 ,

wherein the second alignment mark is a hole that is formed in the supporting plate to be aligned with the third alignment mark, and

wherein the third alignment mark is a mark that is observable through the hole.

6. The method of claim 5 , wherein the disposing the donor film on the acceptor substrate comprises aligning the supporting plate and the acceptor substrate by detecting the third alignment mark through the hole.

7. The method of claim 6 , wherein the disposing the donor film on the acceptor substrate further comprises aligning the supporting plate and the acceptor substrate by emitting a light toward the third alignment mark from a side of the acceptor substrate opposite the donor film.

8. A method of manufacturing an organic light-emitting display apparatus according to a laser-induced thermal imaging (LITI) method, the method comprising:

patterning a transfer layer arranged on a donor film;

disposing the donor film on an acceptor substrate;

laminating the donor film on the acceptor substrate;

transferring the transfer layer of the donor film to the acceptor substrate; and

removing the donor film from the acceptor substrate,

wherein the patterning comprises removing a non-pattern portion of the transfer layer using a laser, and

wherein the laser has a wavelength band of 180 nm to 355 nm.

9. The method of claim 8 , wherein the donor film is resistant to the wavelength band of the laser.

10. The method of claim 1 , further comprising, before the laminating, inserting a fixing member that penetrates respective portions of the donor film and the acceptor substrate.

11. The method of claim 10 , wherein the inserting the fixing member comprises:

disposing a supporting member including a penetration hole on the donor film; and

inserting a penetrating member into the penetration hole of the supporting member and the respective portions of the donor film and the acceptor substrate.

12. The method of claim 10 , further comprising, before the removing of the donor film, removing the fixing member from the donor film and the acceptor substrate.

13. The method of claim 1 , wherein the laminating further comprises applying a pressure to the donor film in a direction toward the acceptor substrate.

14. The method of claim 1 , wherein the transferring comprises transferring the pattern portion of the transfer layer to the acceptor substrate by irradiating a laser to the donor film.

15. The method of claim 1 , wherein the transfer layer comprises one or more layers selected from the group consisting of a hole injection layer (HIL), a hole transport layer (HTL), an electroluminescent layer, a hole suppression layer, an electron transport layer (ETL), and an electron injection layer (EIL).

16. The method of claim 1 ,

wherein the acceptor substrate comprises a thin-film transistor (TFT) and an electrode, and

wherein the transferring comprises transferring the pattern portion of the transfer layer of the donor film to the electrode.

17. The method of claim 16 ,

wherein the acceptor substrate further comprises a pixel-defining layer (PDL) having an opening in a region corresponding to the electrode, and

wherein the patterning comprises patterning the transfer layer, whereby the pattern portion of the transfer layer remains only in a region corresponding to the opening.
