White Organic Light-Emitting Diodes for Display and Lighting Application
Pp. 40-61 (22)
The history of white light organic light-emitting diodes (WOLEDs) can be
dated back to 1993 when Kido and coworkers reported the first OLEDs that emit white
color, i.e., the emitted light contain wavelengths across the entire visible spectrum [1,
2]. From then on, considerable research efforts have been devoted throughout the world
by both academia and industry in developing efficient WOLEDs for next generation
high resolution large area displays and solid-state light sources. In this chapter, the
applications of WOLEDs in display and lighting will first be presented, followed by
introducing the general approaches to achieve white light emission. Finally, challenges
and solutions for large area, high efficiency and high CRI WOLEDs will be posed.
