As the foundation and important core of OLED technology, OLED materials occupy an important position in OLED technology. Higher luminescence lifetimes, quantum efficiencies, lower cost, and OLED materials that are more suitable for industrial applications have been the goal pursued by researchers and application vendors. An organic light emitting diode display, also referred to as an organic electroluminescent display or an organic light emitting display, referred to as an OLED, is a display device that utilizes a phenomenon in which a carrier enters an organic solid layer by a positive and negative electrode under the action of an electric field. In the last 10 years, OLED technology has made remarkable progress, from 5cm products to 107cm OLED samples. Compared with LCD, OLED has all solid state, self-illumination, wide viewing angle, high definition, high brightness, high contrast, high response speed, ultra-thin, low cost, low power consumption, low temperature resistance, shock resistance, soft display and double Features such as face display are considered to be the most ideal and most promising next-generation flat panel display technology. OLEDs can be classified into two types according to the organic light-emitting materials used: one is a small molecule OLED based on a small molecule organic light-emitting material, and the other is a polymer OLED based on a conjugated polymer organic light-emitting material (referred to as PLED). Kodak and Cambridge (referred to as CDT) are the leaders of small molecule OLEDs and polymer OLEDs respectively. The preparation technology of small molecule OLED mainly adopts the method of vacuum evaporation, and the technology is relatively mature. The preparation technology of PLED mainly adopts spin coating, inkjet printing, etc. This preparation technology may greatly reduce the production cost of the device, but the technology is not mature enough.
