Recent Advances in Flexible Organic Light-emitting Devices

White organic light-emitting devices (WOLED's) are of considerable interest owing to their attractive characteristics and potential application to flat panel display and solid-state lighting source. Currently WOLED's are the new increasing point in the area of organic optoelectronics due to their high power efficiency. After a brief overview of the WOLED's operating principles and basic emitting structure, this book presents a review of recent progress in WOLED's structure and materials.
