33‐1: All‐Inkjet‐printed AMOLED Display with Improved Efficiency and Lifetime

Abstract

Inkjet‐printing of organic light‐emitting diodes(OLEDs) is a revolutionary technology aimed at large‐size panel production, high OLED material consumption efficiency and lower manufacturing costs. Here we demonstrate all‐inkjet‐printed 12.4‐inch AMOLED display by developing a novel ink composition for ETL which enables uniform ETL formation with full orthogonality to small‐molecule EML.
