Abstract
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.
