A lot of approach ways for WOLED have been reported since the first report of Kido group. Many researchers are also involved in ongoing efforts to make two or three emissive layers in OLED device. Also, because host-dopant system can significantly improve efficiency and show stable color purity, it was often used in WOLED. Especially, in order to develop the host for high performance, many molecules were designed and synthesized. A system that shows high efficiency with a hole or electron transporting material blended with emitting compounds is being actively considered as a co-host system. |
