The display driver outputs scan signals to drive a display panel. A display driver has a plurality of shift registers, and each of the plurality of shift registers includes a pull-up unit, a driving unit, a pull-down unit and a holding unit. The pull-up unit is electrically connected to a driving node for outputting a driving voltage. The driving unit is electrically connected to the driving node for outputting a first scan signal according to a clock. A pull-down unit is electrically connected to the driving node and the output terminal, for pulling down the voltage level of the driving voltage and the first scan signal, respectively. The holding unit is electrically connected to the driving node.

Abstract: A driving circuit comprises a plurality of shift register (SR). An ith SR among the plurality SR's comprises a resetting circuit, an input switch, a capacitor, and an output circuit. The resetting circuit is used for adjusting a resetting voltage according to a control voltage. The input switch is used for adjusting the control voltage according to an (i−2)th driving signal from an (i−2)th SR among the plurality of SR's, selectively. The capacitor is used for adding a voltage variation of a boosting signal to the control voltage. The output circuit is used for taking an ith input signal as an ith output signal according to the control voltage and the resetting voltage, selectively. The positive edge of the boosting voltage leads the negative edge of the ith input signal.
