摘要： In a driving method of a plasma display panel of the present invention, plural display electrode pairs are divided into plural display electrode pair groups and one field is divided into plural sub-fields. The length of the sustain period is compared to the length of the erase period. If the sustain period is longer than the erase period, sustain discharge and erase discharge are performed for each of the display electrode pair groups, while if the sustain period is shorter than the erase period, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group. For a sub-field with a largest luminance weight or a sub-field with a highest lighting ratio, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group without fail.
