An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two … Ver mais André Bernanose and co-workers at the Nancy-Université in France made the first observations of electroluminescence in organic materials in the early 1950s. They applied high alternating voltages in air to materials such as Ver mais Small molecules Organic small-molecule electroluminescent materials have the advantages of a … Ver mais Shadow mask patterning method The most commonly used patterning method for organic light-emitting displays is shadow masking during film deposition, also called the … Ver mais A typical OLED is composed of a layer of organic materials situated between two electrodes, the anode and cathode, all deposited on a Ver mais Balanced charge injection and transfer are required to get high internal efficiency, pure emission of luminance layer without contaminated emission from charge transporting layers, … Ver mais Structure Bottom emission The bottom-emission organic light-emitting diode (BE-OLED) is the architecture that was used in the … Ver mais For a high resolution display like a TV, a thin-film transistor (TFT) backplane is necessary to drive the pixels correctly.
