A solution based flexible N-type organic TFTs (OTFTs) backplane on polymer film is developed and processed in an existing Gen-2 a- Si TFT production line. The integrated OTFTs device shows good mobility at 1.5 cm2/Vs, Vth at 2V and SS smaller than 1. A Flexible Electrophoretic Display (EPD) module driven by this N-type OTFTs backplane is also developed. The optical performance of this flexible EPD module remains unchanged even after bending operation, which enables the advent of a truly flexible display application in the near future.
