Abstract
A method of driving a plasma display panel is disclosed. The sustain discharge frequency of sustain electrodes and scan electrodes is set to a high level during the first half of a sustain discharge period during which there are few discharges and the effect of saturation need not be considered. On the other hand, the sustain discharge frequency of sustain electrodes and scan electrodes is set to a lower level in order to limit the effect of saturation during the latter half of a sustain discharge period in which the number of discharges is great and saturation cannot be ignored.
