61‐4: All‐Inkjet‐printed EL‐QD Display with Improved Efficiency and Lifetime

Abstract

Inkjet‐printing of electroluminescent quantum dot (EL‐QD) devices is a revolutionary technology aimed at large‐size panel production, high material consumption efficiency and lower manufacturing costs. Here we demonstrate all‐inkjet‐printed 12.4‐inch full color EL‐QD display with 182 ppi resolution. We improved device performance by controling carrier transport property and charge balance through ligand exchange in QDs and ZnMgO surface.
