A method for driving a plasma display panel. A discharge occurs at a selected discharge cell by scan and address pulses to form wall charges in an address period. A setup pulse is applied to a scan electrode in a sustain period. A discharge occurs between sustain and scan electrodes by a wall voltage of the sustain and scan electrodes and a voltage of the setup pulse when the setup pulse is applied. A self discharge occurs between the sustain and scan electrodes when the setup pulse falls, to form space charges. A sustain pulse is applied to the sustain and scan electrodes, and a sustain occurs by the space charges and the sustain pulse.
