The present invention relates to a driving circuit for a display panel, which comprises a pre-charge power supply, a pre-charge switch, a buffer circuit, and a plurality of resistive devices. The pre-charge switch is coupled between the pre-charge power supply and a capacitor of the display panel. The buffer circuit is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals therebetween according to the buffer signal. The driving circuit first closes the pre-charge switch to make the pre-charge power supply charge the capacitor. Then, one of the plurality of driving signals charges the capacitor. Thereby, the driving time can be shortened, and power of the display can be saved by avoiding power consumption on resistors.
