Driving large-sized OLED TVs with an amorphous-silicon backplane

Abstract

A20-in. OLED display driven by an amorphous-silicon backplane has been demonstrated. It has been widely believed that the characteristics of amorphous-silicon TFTs are not sufficient to drive OLED display. This paper challenges this hypothesis and proves that amorphous silicon can be applied to large active-matrix-driven displays and discusses many possible approaches that lead to good front-of-screen quality. Superior-video-image-quality amorphous-silicon-driven OLEDs opens a bright future for a new generation of wall-hanging televisions. © Copyright 2005 Society for Information Display.
