Abstract
In the printed electronics field, it has been needed to realize the manufacturing technologies for inventing mass production phase. We JAPERA, which was organized 2011 as a NEDO project to develop the manufacturing technologies of large area flexible printed electronics, established the automated and continuously operated manufacturing line for which produced the all-printed TFT array flexible film. We operated the offset printer, inkjet printer, screen printer, and slit-die coater. Specialized ink materials, for example Ag nano particle ink for gate electrode and source/drain electrode, highly purified polymer ink for gate insulator, and organic semiconductor ink for TFT active layer have been developed. We have been acquiring successful results of TFT array flexible film by high yield. The applications of our THT array flexible film for making a display device or a sensor device are presented.
