Abstract
In this report, organic thin film transistor (OTFT)-driven active-matrix liquid crystal display (AM-LCD) on flexible polymer substrate is demonstrated. A polymer material, poly (3-hexylthiophene) (P3HT) was used as the active layer and printed by a rubber stamp printing method using a prepattemed silicone elastomer stamp. With this method, the active layer was easily printed on the device without further patterning process. The saturation field-effect mobility of the rubber-stamp-printed TFT array was 0.025 cm2/V·s and the on/off ratio was 104. From the results, a 2″ OTFT-LCD panel with 35 × 24 pixels was successively fabricated and operated using a polycarbonate substrate. In addition, we investigated the reliability of the OTFT device under various conditions with or without a passivation layer to realize more stable devices.
