Webb22 okt. 2024 · As a sub-category of organic semiconductors, OLEDs are carbon-based compounds with structures tailored for photo- or electro-luminescence. They utilize a thin layer of a polymeric or small molecule based organic materials to achieve a desirable wavelength of emission. WebbCharge transport in organic p-conjugated materials at room temperature occurs via a hopping-type mechanism. 19-21 For OLEDs, this mechanism is described as a self-exchange transfer process. The holetransfer process is described as M + M + → M + + M, where M represents a neutral species undergoing charge transfer and M+ the species …
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.
