Embodiment Construction

[0023] Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the embodiments, but may be implemented in other forms.

[0024] figure 1 is a schematic diagram illustrating a method of manufacturing an organic light emitting display according to the present invention.

[0025] refer to figure 1 , providing a substrate 110 on which a pixel electrode is formed. Next, the donor substrate 120 having the organic layer 130 is laminated on the substrate 110 having the pixel electrode. The donor substrate 120 having the organic layer 130 is laminated on the substrate 110 by vacuuming, pressing rollers, and the like.

[0026] Next, the laser radiation device 100 having a spatial light modulator irradiates the donor substrate 120 with a laser beam 150 to form an organic layer pattern on the substrate 110 having the pixel electrodes.

[0027] The formation of...

Abstract

A method of manufacturing an organic light emitting display is provided. The method includes forming an organic layer pattern on a substrate by irradiating a predetermined region of a donor substrate with a laser beam using a laser irradiation device having a spatial light modulator (SLM). The spatial light modulator is used to form an organic layer pattern using a LITI method. It is then possible to adjust various types of incident light to be uniform and have a desired waveform. Accordingly, there is provided a method of manufacturing an organic light emitting display that can form an organic layer pattern without using a mask.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2004-0076668 filed on September 23, 2004, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a method of manufacturing an organic light emitting display, and more particularly to a method of forming an organic layer pattern using a laser irradiation device with a spatial light modulator when the organic layer pattern is formed using a laser induced thermal imaging (LITI) method . Background technique [0004] Generally speaking, an organic light emitting display, as a flat panel display, includes an anode electrode, a cathode electrode, and an organic layer between the anode electrode and the cathode electrode. The organic layer includes at least a light emitting layer. The organic layer may include a hole injection layer, a hole transport layer, an electr...
