PM-OLED principle Character LCD Modules

PM-OLED emitting principle is the use of poor materials, energy level, the release of energy into photons, so we can choose the appropriate material as a light-emitting layer or a light-emitting layer doped with dyes in order to get what we need light color. In addition, generally a combination of electrons and holes are in the tens of nanoseconds reaction (ns) and it is therefore PM-OLED response speed is very fast.OLED Module
PM-OLEM typical structure. PM-OLED typically a glass substrate, ITO (indiumtinoxide; indium tin oxide) anode (Anode), organic light-emitting layer (EmittingMaterialLayer) and the cathode (Cathode), etc., of which, thin, transparent ITO anode and the cathode as a metal camel sandwich the organic light emitting layer sandwiched wherein the anode when the voltage injection hole (Hole) and the cathode to the electron (Electron) when combined with the organic light emitting layer, an organic material to emit light excitation.
At present, better luminous efficiency, widely used in multi-PM-OLED structure, in addition to the glass substrate, the electrode and the organic light-emitting layer of yin and yang, but still need to make the hole injection layer (HoleInjectLayer; HIL), hole transport layer (HoleTransportLayer; HTL), an electron transport layer (ElectronTransportLayer; ETL) and electron injection layer (ElectronInjectLayer; EIL) and other structures, and each of the transport layer to be set between the electrode and the insulating layer, thermal evaporation (Evaporate) relative increase the difficulty of processing, the production process also becomes complicated.Character OLED Display
As the organic material and metal to oxygen and water vapor are quite sensitive, production is completed, and subject to packaging protection treatment. PM-OLED, although the organic thin film to be formed by several layers, then the organic thin film layer thickness of only about 1,000 ~ 1,500 A ° (0.10 ~ 0.15um), the entire display panel (Panel) of the package plus desiccant (Desiccant) is less than the total thickness of 200um (2mm), with the thin edge.
