    摘要: The disclosure provides a gate driving circuit on array applied to a display panel with charge sharing pixel structure. In particular, the gate driving circuit is adapted to receive multi-phase clock signal and includes a plurality of shift registers. Each shift register includes a driving circuit including a first driving transistor and a second driving transistor, a pull-down unit and at least one pull-up unit, so that is capable of generating mutually non-overlapped main gate driving signal and sub gate driving signal. Furthermore, the advantage of the disclosure is to provide a gate driving circuit with simplified circuit structure and circuit layout.

    摘要: A shift register circuit includes plural shift register stages for providing plural gate signals. Each shift register stage includes an input unit, a pull-up unit, a pull-down unit, a control unit and an auxiliary pull-down unit. The input unit is put in use for outputting a driving control voltage according to at least one first input signal. The pull-up unit pulls up a corresponding gate signal according to the driving control voltage and a system clock. The pull-down unit pulls down the corresponding gate signal to a first power voltage according to a control signal. The control unit is utilized for generating the control signal according to the corresponding gate signal. The auxiliary pull-down unit pulls down the driving control voltage to a second power voltage according to a second input signal.
