Abstract
A method for driving a plasma display panel that includes a plurality of discharge cells including a display electrode pair composed of a scan electrode and a sustain electrode. One field period includes a plurality of subfields each including an initializing period, an address period and a sustain period. The method includes applying at least two kinds of sustain pulses to one electrode of the scan electrode and the sustain electrode in the sustain period, the two kinds of sustain pulses including a first sustain pulse as a reference and a second sustain pulse rising more steeply and falling more gently than the first sustain pulse. In the method, a drive waveform voltage applied to the one electrode includes a last drive waveform voltage in the sustain period and a predetermined number of the second sustain pulses continuously disposed immediately before the last drive waveform voltage.
