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.
