    Organic light-emitting diode(OLED) technology has achieved significant penetration in the commercial market for small, low-voltage and inexpensive displays. Present and future novel technologies based on OLEDs involve rigid and flexible flat panel displays, solid-state lighting, and lasers. Display applications may range from hand-held devices to large flat panel screens that can be rolled up or hung flat on a wall or a ceiling.

    Organic Electroluminescence gives an overview of the on-going research in the field of organic light-emitting materials and devices, covering the principles of electroluminescence in organic thin films, as well as recent trends, current applications, and future potential uses. The book begins by giving a background of organic electroluminescence in terms of history and basic principles. It offers details on the mechanism(s) of electroluminescence in thin organic films. It presentsin-depth discussions of the parameters that control the external electroluminescence quantum efficiency including the photoluminescence quantum yield, the light-output coupling factor, carrier/charge injection and transport, and electron and hole recombination processes in organic semiconductors.

    The authors address the design and the characterization of amorphous charge transport materials with high glass transition temperatures, light-emitting small molecules and conjugated polymers. The book covers state-of-the-art concepts and technologies such as fluorescent and phosphorescent OLEDs, various approaches for patterning organics, and active matrix organic emissive displays including their back panel thin film transistors and pixel electronics. It concludes by summarizing future directions for OLEDs in organic light-emitting displays, large area distributed solid state light sources, and lasers using organic thin films, nanostructures, and photonic crystals.
