초록

디스플레이는 브라운관을 시작으로 PDP(Plasma Display Panel), LCD(Liquid Crystal Display) 이후 AMOLED(Active Marix Organic Light Emitting Diode) 순으로 시장을 형성하고 있다. 유기발광다이오드 OLED는 4차 산업혁명을 준비하는 각 국가들의 발전을 위한 핵심 분야로 인정받고 있는 기술이며, 특히 국내 최고업계 삼성 디스플레이, LG디스플레이는 OLED의 90%이상의 점유율로 시장을 주도하고 있다. 현재 AMOLED는 접거나 휠 수 있는 영역으로 옮겨왔으며, 이와 같은 기술이 가능한 이유는 플렉서블 기판상에 TFT(Thin Film Transistor)와 OLED가 형성가능하기 때문이다. 향후 스트레처블 디스플레이로 그 기술은 이동할 것이며, 이를 위해서는 늘어나는 기판 소재 개발이 우선 진행되고, 다음으로 TFT, OLED 소자 역시 늘어날 수 있는 재료로 구현되어야 할 것이다.

Starting with cathode ray tubes, displays are forming markets in the order of active marix organic light emitting diode (AMOLED) after PDP (Plasma Display Panel) and LCD (Liquid Crystal Display). OLED is recognized as a key field for the development of each country preparing for the fourth industrial revolution, and especially Samsung Display and LG Display, which are the top industries in Korea, are leading the market with more than 90% of OLED shares. Currently, AMOLED has moved to the area that can be folded or bent. This technology is possible because TFT (Thin Film Transistor) and OLED may be formed on a flexible substrate. In the future, the technology will move to stretchable displays, and for this, the development of substrate materials is first, and then TFT and OLED devices should also be implemented with stretchable materials.
