Reliable and Uniform Thin-Film Transistor Arrays Based on Inkjet-Printed Polymer Semiconductors for Full Color Reflective Displays

Abstract

Stable uniform performance inkjet?printed polymer transistor arrays , which allow demonstration of flexible full?color displays, were achieved by new ambient processable conjugated copolymer semiconductor, and OTFT devices incorporating this material showed high mobility values > 1.0 cm 2 V ?1 s ?1 . Bias?stress stability of the devices was improved with a channel?passivation layer, which suppresses the density of trap states at the channel interface
