摘要: 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.

摘要: A shift register is provided and includes a first shift registering unit and a second shift registering unit. The first shift registering unit generates a first trigger signal at a first output terminal and includes a first pull-down circuit. The second shift registering unit receives the first trigger signal and generates a second trigger signal at a second output terminal. The first trigger signal and the second trigger signal are sequentially asserted. The second shift registering unit includes a second pull-down circuit. The first pull-down circuit and the second pull-down circuit perform pull-down operations at different times. When the first pull-down circuit does not perform the pull-down operation, the second pull-down circuit performs pull-down operations to the first output terminal.
