Solution-processed organic TFT array for active-matrix LCDs on a plastic substrate

— Organic TFTs (OTFTs) have been developed with a novel solution-processed gate insulator of poly(4-vinylphenol) (PVP) with the addition of octadecyltrichloro-silane (OTS) and a solution-processed organo-silver electrode/wire to improve the performance of an OTFT and to maked high-throughput-manufacturing process possible. Solution-processed PVP has also employed for a buffer layer on a plastic substrate. The OTFT backplane with these solution-based organic-material technologies has been successfully applied to drive a 2.5-in. QQVGA (160 × 120 pixels) AMLCD with a resolution of 79 dpi.
