A gate driver circuit for IGZO TFTs driven by two clock signals

Abstract

In this paper, a gate driver circuit for In-Ga-Zn-O thin-film transistors (TFTs) driven by only two clock signals is reported. In this circuit, the TFTs are turned off with a negative VGS by the two clock signals. As a result, it works properly and suppresses power consumption increase even though the TFT VT shifts in the negative direction. © 2012 Copyright Taylor and Francis Group, LLC.
