Abstract

We have fabricated a solution processed high resolution (15.0 inch diagonal sized SXGA, 110ppi) organic thin film transistor array to drive the liquid crystal display, where the whole layers except an electrode were formed by organic materials using solution process. The TFT in the array exhibited an average field effect mobility of 0.2~0.3 cm²/Vs, an on/off current ratio of 10⁶, and obtained good uniformity as well as high mobility of OTFT performance.
