대면적 OLED증착용 서큘러소스의 성능개선

국문 초록 (Abstract)

유기발광다이오드(OLEO)증착을 위한 서큘러소스의 열전달 해석을 통하여 온도분포를 연구하였다. 대면적의 OLEO용 평판의 유기물증착을 위해 서큘러소스가 사용되는데, 소스내의 유기물이 가열되고, 승화되어 증착된다. 유기물의 수율을 높이기 위해 히터설계를 개선하고, 이에 대한 열전달해석을 수행하였다. 그리고, 효율을 높이기 위한 새로운 제조공정인 OYPO공정의 개념과 유도 및 열전달특성에 관한 기본적인 연구결과를 제시하였다.

Temperature distribution of the circular heat source was studied by analyzing the heat transfer of the environment of the circular source for OLED. Circular nozzle source was used to fabricate thin organic layer as the organic material in it was heated, vaporized and deposited to the large size flat panel. Circular source for large size fat panel for OLED has been modified to obtain higher productivity and heat transfer characteristics was predicted using computer simulation. Fundamentals for OVPD process also was presented to estimate flow and heat transfer characteristics of the process which can increase the material efficiency.
