Abstract

Given with the success of OLEDs in many consumer electronics, the search for scalable, additive patterning technique for organic thin films is still continued because the established fabrication method for OLEDs relies on thermal evaporation assisted with fine-metal mask technique, with a low material utilization efficiency and a limited scalability for sequential patterning of RGB subpixels. This talk will introduce recent efforts made for organic vapor-printing (OVJP combining the additive, scalable nature of inkjet printing and the solvent-free advantages of thermal evaporation, to work better with flexible electronics and to allow for batch definition of multiple pixels for display applications.
