Abstract:
1. A method of driving a plasma display panel, which is a mixed scan-sustain-type plasma display panel for displaying a desired image by carrying out each of set-up discharge, set-up discharge erase, write discharge, sustain discharge, and sustain discharge erase for each scan line of a plurality of scan lines of an AC plasma display panel that is made up of a plurality of display cells arranged in a lattice and includes a plurality of pairs of a scan electrode and a sustain electrode for the respective scan lines; said method comprising the steps of: performing said set-up discharge by applying a set-up discharge pulse which is a gradually rising pulse to the scan electrode of said each scan line; performing said sustain discharge by applying a sustain pulse to each of the scan electrodes and sustain electrodes of scan lines other than the scan line in which said sustain discharge erase is to be performed and other than the scan line in which the immediately preceding set-up discharge was performed; and carrying out said set-up discharge erase by applying, to the sustain electrode paired with the scan electrode to which said set-up discharge pulse was applied to thereby the immediately preceding set-up discharge, a set-up discharge erase pulse which is a gradually rising pulse of the same polarity as the sustain pulse that is applied to the scan electrode of that scan line.
