Abstract:
1. A method of driving a plasma display panel in which the driving is performed by time division of one frame into one or more sub-fields, wherein after power is supplied to the panel, the one or more sub-fields comprise a sustain period during which a first waveform is applied to one of a scan electrode and a sustain electrode and a second waveform different from the first waveform is applied to the other electrode, a voltage difference between the scan electrode and the sustain electrode during the sustain period is smaller than a voltage at which the sustain discharge is initiated, such that a sustain discharge does not occur, the one or more sub-fields additionally comprise a reset period during which a reset discharge occurs, the reset period being followed by the sustain period, and the first waveform is alternating, and the second waveform is non-alternating with a positive polarity.
