ABSTRACT:
In a drive method of a mixed scan-sustain type of plasma display panel, set-up discharge is performed in the next scan line to be scanned when any particular scan line is in a write period. At this time, a first set-up discharge pulse, which is a gradually rising pulse of the opposite polarity of the scan pulse, is applied to scan electrodes of the scan line that is in the set-up discharge period, and a second set-up discharge pulse, which is a rectangular or gradually rising pulse of the same polarity as the scan pulse and of lower voltage than the scan pulse, is applied to the sustain electrodes. In addition, a set-up discharge erase pulse for eliminating set-up discharge and a sustain erase pulse for eliminating sustain discharge are impressed with the same gradually falling pulse shape.
