Vacuum evaporation process with metal mask using LTPS (Low Temperature Poly Silicon TFT) backplane is well established OLED production process. However this technology is not applicable for large sized display like TV. Various technologies to break through this constraint have been proposed so far. In this paper pros and cons of these proposed technologies are discussed and new approach, micro silicon TFT with unique anneal technology and laser transfer OLED process, is presented.
