Abstract

A laser induced thermal imaging apparatus for fabricating an organic light emitting display is provided. The laser induced thermal imaging apparatus includes a stage where a substrate is positioned; a transport device for transporting a donor substrate; a laminator for laminating the substrate to the donor substrate; a laser optical unit for performing the LITI, and a chamber supplied with an atmospheric pressure of an inert gas in which the stage, the laminator, and the laser optical unit are positioned.

Description

[0001] This application claims the priority of Korean Patent Application No. KR2004-68758 filed on August 30, 2004, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The invention relates to a laser induced thermal imaging apparatus, in particular to a laser induced thermal imaging apparatus used for manufacturing an organic light emitting display. Background technique [0003] Generally among flat-panel displays, organic light-emitting displays (OLEDs) have a fast response speed of less than 1 ms, low power consumption, and are emissive displays, so that there is no viewing angle problem, and they are used to display moving pictures regardless of size The display medium will be more advantageous. In addition, it can be manufactured at low temperature and the process of manufacturing organic light-emitting displays based on conventional semiconductor process technology is also simple, making it considered as a next-generation flat p...
