ABSTRACT:
A plasma display apparatus has a waveform of a driving voltage supplied from a driver. The waveform has a sustaining period when a sustaining pulse is alternately applied to scanning electrodes and sustain electrodes for keeping discharge. Besides, the waveform has an erasing period when a ramp voltage pulse whose polarity differs from that of a sustaining pulse is applied to an electrode, which differs from an electrode where a last pulse of the sustaining pulse is applied. As a result, false discharge is prevented, and a stable image can be displayed.
