Patent ID: 6963320

Claim:
A driving method of a plasma display panel comprising plural first and second electrodes that extend in a first, common direction, adjacent to each other, and plural third electrodes that extend in a second direction, perpendicular to the common direction, the method comprising: applying a scan pulse sequentially to the plural second electrodes in an address period during which an address discharge, to select a cell to be lit, is caused to occur; after the scan pulse is removed, applying an auxiliary scan pulse to the first electrode that makes up a pair of electrodes with a second electrode to which the scan pulse has been applied, to form a display line; adjusting a number of times of sustain discharges in a display field, wherein: when the number of times of sustain discharges in a display field is decreased, increasing the width of the scan pulse and not applying an auxiliary scan pulse, and when the number of times of sustain discharges in a display field is increased, decreasing the width of the scan pulse and applying an auxiliary scan pulse.
