54.4: 4.1 inch Top‐Emission AMOLED on Flexible Metal Foil

Abstract

Abstract We have developed a 4.1 inch AMOLED display with top emission structure on stainless steel foil. The p‐channel TFTs on metal foil exhibited the field‐effect mobility of 75.1 cm 2 /Vs, threshold voltage of −3.9V, and subthreshold swing of 0.9V/dec. Active‐matrix back planes were fabricated with the poly‐Si TFT with a conventional pixel circuit consisting of 2 TFTs and 1 cap. The scan driver circuits with PMOS were integrated on the metal foil.
