With the development of scientific and technological progress, TFT LCD has completely replaced the traditional display technology. Organic light-emitting diodes (OLEDs) are considered to be thefuture of the TFT LCD, the future of the most development potential of the flat display technology. The principle of light emission is the potential difference between the electrons injected into the electrons and the holes due to the applied voltage so that these electron holes are moved in the film layer and the recombination is generated. This recombination energy will High energy and non-stable excitation state, when the light energy is released when it will return to the low energy and stable ground state, resulting in the so-called injection-type electroluminescence. It has the advantages of active light emission, high response speed characteristics, power saving, light and so on, and the other process is simple and low cost, can be applied to the characteristics of flexible panels, known as one of the most ideal display, but still can not put a lot of Production, the main reason is that the panel can not improve the uniformity and deterioration of components and other issues, the study will address the above issues and add the rest of the method to improve the method.
