Description

Organic light-emitting diodes (OLEDs) are opening up exciting new applications in the area of lighting and displays. OLEDs are self emissive and by careful materials and device design can generate colours across the visible spectrum. Together with simple monolithic fabrication on a range of different substrates, these diverse material properties give OLEDs key advantages over existing display and lighting technology. This important book summarises key research on materials, engineering and the range of applications of these versatile materials.Part one covers materials for OLEDs. Chapters review conjugated polymers, transparent conducting thin films, iridium complexes and phosphorescent materials. Part two discusses the operation and engineering of OLED devices. Chapters discuss topics such as highly efficient pin-type OLEDs, amorphous organic semiconductors, nanostructuring techniques, light extraction, colour tuning, printing techniques, fluorenone defects and disruptive characteristics as well as durability issues. Part three explores the applications of OLEDs in displays and solid-state lighting. Applications discussed include displays, microdisplays and transparent OLEDs, sensors and large-area OLED lighting panels.Organic light-emitting diodes (OLEDs) is a standard reference for engineers working in lighting, display technology and the consumer electronics sectors, as well as those researching OLEDs.
