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

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 V GS by the two clock signals. As a result, it works properly and suppresses power consumption increase even though the TFT V T shifts in the negative direction.
