 Currently the most commonly used to produce the electron transport layer material must film  LED Bulb  stability, high thermal stability and good electron transport property, generally fluorescent dye compound is usually used. Such as Alq, Znq, Gaq, Bebq, Balq, DPVBi, ZnSPB, PBD, OXD, BBOT so on. The hole transport layer fluorescent material is an aromatic amine compounds, such as TPD, TDATA and other organic materials.

LED Module

The organic light-emitting layer material must have a strong solid state fluorescence, the carrier transport properties, good thermal stability and chemical stability, high quantum efficiency and capable of vacuum vapor deposition properties, generally a material for the organic light emitting layer is usually an electron transport layer or the hole transport layer is the same material used for, for example, is widely used Alq green, Balq, and DPVBi were widely used in the blue.

  LED Flexi Strip

Generally, OLED light emitting material may be classified into two types: small molecular OLED and a polymer OLED (also called PLED). Small molecule OLED and polymer OLED differences mainly in the device fabrication process is different: small molecule devices mainly used vacuum thermal evaporation process, the polymer devices are used spin coating or spray printing process. Small molecule materials manufacturers are: Eastman, Kodak, Idemitsu Kosan, Japan INK manufacturing, Mitsubishi Chemical; polymer materials manufacturers are: CDT, Covin, Dow Chemical, Sumitomo Chemical and so on. Current international and OLED-related patents have been more than 1400 copies, of which there are three basic patent. Small molecule OLED basic patent owned by the U.S. company Kodak, polymer OLED patents by the British CDT (Cambridge DisPlay Technology) and the United States Uniax Company.
