A method for driving a plasma display panel having a plurality of scan, sustain, and address electrodes is presented. Reset, address, and sustain discharge are performed by applying a driving waveform to a scan electrode while the sustain electrode is biased at a ground voltage. Address electrode is set to be at a positive voltage while the voltage of the scan electrode is gradually increased during the reset period. The foregoing driving voltage scheme obviates the need for a separate driving board for the sustain electrode. A single integrated board is sufficient for driving the scan and sustain electrodes. Various slopes for rising and falling portions of the scan waveform during the reset period are presented. A falling only reset period in second and subsequent subfields is used.
