In general, the process of manufacturing an optoelectronic device on a glass substrate uses a PVD, Thermal Evaporation. However, the deposition process takes a long time because a continuous process is difficult, and there is a problem in mass production. In addition, it is difficult to apply the deposition process to optoelectronic devices using a flexible material as a substrate. For that reason, PET film, which is a flexible material, has poor thermal stability and is not suitable for high-temperature deposition or high-temperature curing processes. Thus, this study not only solved the problem of the deposition process, but also produced a flexible photoelectric device and module using the printing process, which is a process suitable for flexible materials. The printed electronic equipment used is a D-Bar-Coating equipment, and a bar with a D-bar area ratio of 6.6 was mounted to coat the electron injection layer (EIL), the electron transport layer (ETL), and the emitting layer (EML). A flexible OLED device was manufactured by coating the hole transport layer (HTL) using PEDOT:PSS and the lower electrode using silver paste with high viscosity using a screen-printing equipment. In addition, for a large area OLED lighting module, it was produced using a printing process on a PET substrate coated with ITO, not a glass substrate, and coating all areas with ink would result in significant material waste, so a modular work was performed to coat a large area efficiently.
