Webb29 jan. 2024 · Organic materials used in OLEDs The cathode is a layer of metal or other conductive material that serves as the source of electrons. The anode, which allows … With this method, the OLED materials produce white light which is then filtered to obtain the desired RGB colors. This method eliminated the need to deposit three different organic emissive materials so only one kind of OLED material is used to produce white light. It also eliminated the uneven degradation rate … Visa mer 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 … Visa mer A typical OLED is composed of a layer of organic materials situated between two electrodes, the anode and cathode, all deposited on a substrate. The organic molecules are electrically conductive as a result of delocalization of pi electrons caused by Visa mer Small molecules Organic small-molecule electroluminescent materials have the advantages of a wide variety, easy to purify, and strong chemical modifications. In order to make the luminescent materials to emit … Visa mer 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 acridine orange dye, either deposited on … Visa mer Balanced charge injection and transfer are required to get high internal efficiency, pure emission of luminance layer without contaminated emission from charge transporting layers, and high stability. A common way to balance charge is optimizing the … Visa mer Structure Bottom emission The bottom-emission organic light-emitting diode (BE … Visa mer Shadow mask patterning method The most commonly used patterning method for organic light-emitting displays is shadow masking during film deposition, also called the "RGB … Visa mer
