✦ Synopsis

Organic Light Emitting Diodes: Principles, Characteristics, and Processes presents recent developments in organic electroluminescence and their application to light emitting diodes. In six chapters and complete with an extensive set of references, it describes and illustrates the physical principles of organic LEDs and their electrical and optical characteristics with a wide range of examples and practical studies. The author presents a unified approach to the description and functioning of organic LEDs, based on a comprehensive background of relevant physical processes and provides a clear foundation for the prediction and design of new improved electroluminescent devices.
