The present disclosure relates to a PDP, and more particularly, to a method and apparatus of driving a PDP. The method includes the steps of initializing the cells by consecutively supplying a preliminary initialization waveform in which a square wave pulse and a ramp-down waveform are combined, a first ramp-up waveform for causing a write discharge to occur, a first ramp-down waveform for causing an erase discharge to occur, a second ramp-up waveform for causing a write discharge to occur, and a second ramp-down waveform for causing the erase discharge to occur to one of the scan electrode Y and the sustain electrode Z; selecting the cells by supplying a data to the address electrodes X and supplying a scan pulse to at least one of the scan electrode Y and the sustain electrode Z; and performing a display by alternately supplying a sustain pulse to the scan electrodes Y and the address electrodes X. Therefore, an address operational margin can be secured and the number of an initialization discharge can be reduced through stabilization of initialization. It is thus possible to improve a contrast characteristic and an address discharge characteristic. |
