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

Abstract

Abstract— 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 cm 2 /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.
