유기 발광 다이오드의 광 추출 효율 개선을 위한 다양한 광학기능구조의 적용

Recent years, OLEDs have been progressed intensively and been widely applied to Display and Lighting industry,Almost 100% internal quantum efficiency was achieved by developing new materials and structure optimization. However, external quantum efficiency was still low due to total internal reflection of light inside OLED devices and absorption of light at the surface of metal electrode. In order to improve external quantum efficiency of OLED devices, various kinds of optical functional structures were introduced to inside and outside of OLED devices to increase light extraction efficiency. In this paper, various efforts to apply optical functional structures in OLED devices were reviewed and way to improve light extraction efficency of OLED devices were discussed.
