Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
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.
