We introduce novel driving methods of pull-down unit in a gate driver circuit for enhancement and depletion mode a-IGZO thin-film transistors (TFTs). Using 3T1C diode connection structure, our circuit can compensate for VTH of pull-down unit in the enhancement mode and can be normally operated in the depletion mode.
