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.
