A flexible,organic QVGA display with gray‐scale capability

Abstract— A flexible 4.7‐in. QVGA active‐matrix display was demonstrated, containing 76,800 solution‐processed organic transistors. The combination of our plastic active‐matrix backplane with electrophoretic‐ink display material developed by E‐Ink resulted in a reflective low‐power display with paper‐like appearance. By using high‐performance organic transistors, it was possible to generate 2‐bit images on the display. The display can be bent to a radius below 2 cm.
