초록

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.
