Wettability patterning technology for organic displays

We developed a simple and versatile patterning method for advanced organic displays with high resolution and uniformity in large area. Our patterning method involves the optical formation of selective wetting regions, where a regular array of functional polymer patterns is obtained by a standard spin-casting process. It is demonstrated that polymeric semiconductors and light-emitting polymers can be patterned to produce periodic arrays with feature resolution down to sub-micrometers using the selective wettability. This wettability-based patterning technique of soluble functional polymers would be directly applicable for organic displays and plastic electronics.
