Abstract

차세대 디스플레이로서, 특히 휴대기기를 위한 플레깃블 디스플레이에 대한 관심이 증가되고 있다. 지난 몇 년간 계속적으로 연구가 이루어져 왔음에도 불구하고, 플렉시블 디스플레이는 아직 하나의 '제품'으로서 시장에 진입하지 못하고 있다. 플렉시블 디스플레이는 플라스틱이나 메탈 호일, 플렉시블 유리와 같은 플렉시블 기판이 쓰이는데, 이것은 가벼우면서 얇고 강하며 제조 측면에서 높은 생산성을 가질뿐만 아니라 착용이 가능할 정도의 자유로운 디자인이 가능하다는 장점을 가지고 있다. 이러한 많은 장점으로 인해 플렉시블 디스플레이의 연구와 개발이 빠르게 진행되고 있다. 지난 몇 년 동안 개발된 전기영동(electrophoretic), 유기전계발광(OLED, organic light-emitting diode), 액정(liquid-crystal)과 관련된 플렉시블 디스플레이에 대해 성능 등을 알아보고, 플렉시블 디스플레이용으로 개발된 플라스틱 기판과 그 위에 형성된 유기박막트랜지스터(OTFTs, organic thin film transistors)의 특성을 분석한다. 그리고 oTFTs의 성능과 제작공정의 이해를 위해 self organized process에 대해 설명하고 마지막으로 중요 연구 과제를 제시한다.
