    • A gate driver has a plurality of shift registers. Each of the shift registers has at least three input terminals, two signal input terminals, a pull-up circuit, a driving circuit, a stability pull-down control circuit, and a stability pull-down circuit. The three input terminals of each shift register receive three different clock signals. Accordingly, the driving circuit and the stability pull-down control circuit of each shift register are controlled according to the three clock signals, such that a glitch causing by the coupling effect of the parasitic capacitor of the driving circuit is avoided and the stability of the gate driver is improved.

    • A shift register circuit has a plurality of shift registers. Each of the shift registers has at least four input terminals, a signal input terminal, an output terminal, a pull-up circuit, a driving circuit, a stability driving circuit, and a pull-down circuit.
