Abstract

We have developed surface energy controlled ink-jet printing technique with UV irradiation on novel polyimide. Predefined surface energy patterns control the flow and spreading of ink-jetted water-based electrode droplets on the polyimide film. Line width of 20 μm and space of 2 μm has been fabricated. In this study, we have successfully fabricated an active-matrix organicthin film transistor (AM-OTFT) array in which the channel length is 5 μm on the plastic substrate applying this technique. Moreover, high resolution of 160 ppi flexible electrophoretic displays consisting of this AM-OTFT backplane was demonstrated.
