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 cm2 V-1s–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.
