Flexible electrophoretic display driven by solution‐processed organic thin‐film transistors

— An organic thin-film-transistor (OTFT) backplane has been fabricated by using a solution-processed organic semiconductor (OSC) and organic insulators. The OSC, a peri-xanthenoxanthene derivative, provides a mobility of 0.5 cm2/V-sec. These organic materials enhance the mechanical flexibility of the backplane. The developed backplane successfully drives a 13.3-in. flexible UXGA electrophoretic display that can operate when bent at a radius of 5 mm.
