63.2: AMOLED Displays Using Transfer‐Printed Integrated Circuits

Abstract

Abstract Active‐matrix OLED (AMOLED) displays have been fabricated using backplanes with transfer‐printed microscale silicon integrated circuits (ICs) in place of conventional thin‐film transistors (TFTs). The microscale integrated circuits were transfer printed onto a glass substrate and interconnected using a single‐level, thin‐film metallization process. The resulting OLED display exhibited good pixel‐to‐pixel luminance uniformity, high luminance, and excellent control. The transfer‐printing process achieved good positional accuracy and high yield.
