A class of organic functional materials is promising as a low-cost alternative to inorganic materials like silicon for electronic and optoelectronic applications such as flexible displays, electronic papers, and smart cards. For example, organic light emitting diodes have attracted great attention due to bright, highly-efficient, and thin characteristics. Moreover, a substantial progress has been currently made in the realization of an array of organic thin-film transistors which provides an essential backplane for flexible displays in the roll-to-roll process. We developed a simple and versatile patterning technique for advanced organic displays with high resolution and uniformity in large area on a surface commanding layer. 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 inscription. |
