Display-pixel performances driven by contact-limited switching transistors

Abstract

In this paper, a direct link between contact properties of the transistor and electrical behaviors of the display system is established. Employing a liquid-crystal display driven by organic thin-film transistors as a model platform, systematic simulation of the image pixel circuit is performed to investigate this critical relationship. An elevated contact resistance at the transistor level is found to have a profound impact on charging dynamics of cell capacitors, revealing the importance of rendering such effects in designing advanced display electronics.
