Abstract
A driving method of a plasma display panel in which scan electrode lines and sustain electrode lines are parallel to each other and address electrode lines are spaced from and intersect the scan electrode lines and the sustain electrode lines, includes temporally dividing a unit frame into a plurality of subfields, generating a driving signal having a reset period, an address period, and a sustain period for each subfield, detecting an average signal level for the unit frame, alternately applying a first sustain pulse which reaches a first voltage with a rising slope and a second sustain pulse which reaches a ground voltage with a falling slope to the scan electrode lines and the sustain electrode lines, and controlling a timing of alternately applying in accordance with the average signal level for the unit frame.
