In the proposed gate driver circuit, pull-down TFTs are AC-driven with a duty ratio of 33.3% through CLK pulse instead of DC-driven through VDD power line. The simulation result exhibits output pulse of 1069th stage, 1071st stage, and 1073rd stage output pulse based on FHD, frame frequency of 120 Hz.
