Abstract
A method of driving a plasma display panel including discharge cells, each at an intersection of a scan electrode and a sustain electrode, and a data electrode. One field period is divided into a plurality of sub-fields, each having an initializing period, writing period, and sustaining period. The sustaining period of at least one sub-field has a first sustaining period and a second sustaining period. In the first sustaining period, a transition period of a sustain pulse applied to the scan electrode is not temporally overlapped with a transition period of a sustain pulse applied to the sustain electrode. In a second sustaining period, a transition period of the sustain pulse applied to the scan electrode is temporally overlapped with a transition period of the sustain pulse applied to the sustain electrode. The second sustaining period is included at least at the end of the sustaining period.
