The OLED Preparation process TFT Display Modules

In mainland China, the preparation of the OLED display device is still in the laboratory stage, but has reached the edge of the pilot, so we will mainly discuss the laboratory OLED preparation process.
Laboratory, pilot or mass production of OLED device fabrication process is basically the same, the main difference is that the device vacuum deposition equipment. Laboratory ships optional manual vacuum deposition equipment monolithic sample deposition, so that experimental samples in different types of production; the pilot lines generally use a vacuum vapor deposition apparatus of the semi-automatic continuous multi-chip sample vapor deposition, so that within a small batch switch; production line is generally fully automated vacuum deposition equipment water sample vapor deposition (or line deposition technology and process), in order to increase yields, reduce product cost. It is reported that some institutions are research tries to spin coating process technology in the production line for production of OLED products.
Preparation of the OLED Display Module device: ITO glass cleaning → lithography → cleaning → pretreatment → the vacuum evaporation organic layer → vacuum deposition back electrode → vacuum evaporation protective layer → packaging → cutting → Test → Module assembly → product testing and aging experiments and a dozen procedures.
