Abstract
Organic light emitting diode (OLED) technology has experienced substantial progress in the last couple of decades and is emerging as a strong flat panel display technology with new products ranging from mobile displays to small-size TVs introduced into the marketplace every year. After a brief review of the history and an introduction of basic device structures, this chapter will explain how OLEDs work by diving into the three key electroluminescent process steps: charge injection, charge transport, and charge recombination and light emission. This is followed by discussions on device fabrication and operation which cover topics such as degradation and light extraction. This chapter will end with a brief discussion on the future directions in the OLED research and development.
