Organic light-emitting diodes (OLEDs)

Abstract

Organic light-emitting diode (OLED) technology has experienced a substantial growth in the last three decades. It has emerged as a strong flat panel display technology with many new products ranging from mobile displays to TVs introduced into the marketplace every year. After a brief review of the history of OLED development, this chapter will explain how OLEDs work by diving into the key electroluminescent process steps: charge injection, charge transport, and charge recombination and light emission. Then the focus will shift to detailed discussion on OLED device structure and materials. This is followed by a summary of recent research topics and latest results. After a quick discussion on device fabrication, degradation, and encapsulation, this chapter will end with a brief discussion on the future directions of OLED research and development.
