What are organic light-emitting diodes (OLEDs)? Organic light-emitting diodes are devices made from ultrathin organic layers which light up when they are connected to voltage. They are comprised of an organic layer sequence (typical thickness about nm), which is inserted between an anode and a cathode. What applications are organic materials used for? Organic light-emitting diodes are already used for displays in small electronic appliances such as mobile telephones, car radios and digital cameras. OLED Lighting and Signage Due to the rapid increase in the efficiency of these illumination diodes, which has already surpassed inorganic illumination diodes in the case of green diodes, OLEDs are opening up new markets as two-dimensional illuminants, in particular for textured surface illumination.

OLED Microdisplays Organic Solar Cells Organically based solar cells represent a new class of thin-layer solar cells which offer price advantages over traditional silicon systems. OLED Info | OLED TV, Displays, Screens, Lighting, Information and News. OLED. Prototype OLED lighting panel developed by Lumiotec Demonstration of a flexible OLED device There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell or LEC, which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes. An OLED display works without a backlight.

History[edit] The first observations of electroluminescence in organic materials were in the early 1950s by André Bernanose and co-workers at the Nancy-Université, France. The first diode device was reported at Eastman Kodak by Ching W. Working principle[edit] Schematic of a bilayer OLED: 1. Indium tin oxide (ITO) is commonly used as the anode material. Small molecules[edit]
