Abstract

Abstract : Back channel etched (BCE) structure TFTs have been developed for larger LCD TVs with higher resolution. We developed 5 mask 85 inch 8K4K AMLCDs, and now are focusing on the 4 mask process. For high resolution OLED TVs, self‐aligned coplanar structure TFTs have been developed to reduce the parasitic capacitance. We have been developing low resistive Cu‐based self‐aligned coplanar TFT for 4K2K top emission (T/E) ink jet printing (IJP) AMOLEDs.
