Abstract
A shift register circuit with waveform-shaping function includes plural shift register stages. Each shift register stage includes a first input unit, a pull-up unit, a pull-down circuit, a second input unit, a control unit and a waveform-shaping unit. The first input unit is utilized for outputting a first driving control voltage in response to a first gate signal. The pull-up unit pulls up a second gate signal in response to the first driving control voltage. The pull-down circuit is employed to pull down the first driving control voltage and the second gate signal. The second input unit is utilized for outputting a second driving control voltage in response to the first gate signal. The control unit provides a control signal in response to the second driving control voltage and an auxiliary signal. The waveform-shaping unit performs a waveform-shaping operation on the second gate signal in response to the control signal.
