Patent ID: 7800555

Claim:
A method of driving a plasma display panel which comprises: a substrate on which a plurality of pairs, each one of which pairs is formed of a scan electrode and a sustain electrode, are placed; and another substrate, on which a plurality of data electrodes are so arranged to intersect with the scan electrodes and the sustain electrode at right angles, confronting the substrate, the method comprising the steps of: dividing one field into a plurality of sub-fields, each one of the sub-fields has an addressing period during which a scan pulse is applied to the scan electrodes and a data pulse is applied to the data electrodes, and a sustaining period during which a sustain pulse is applied to both of the scan electrodes and the sustain electrodes; defining a time interval between a scan pulse applied lastly during the addressing period and a sustain pulse applied firstly during the sustaining period as a last pulse-interval; and setting the last pulse-interval of at least one sub-field of a lower part of grayscale, which lower part is darker than a predetermined level of the grayscale, longer than the last pulse-intervals of other sub-fields.
