Patent ID: 8013808

Claim:
A driving method of a plasma display panel for displaying an image comprising a step of measuring a power-on accumulated time of the plasma display panel, wherein one field includes a plurality of subfields having: an initializing period for causing initializing discharge in a discharge cell, the discharge cell having a display electrode pair including a scan electrode and a sustain electrode; an addressing period for causing writing discharge in the discharge cell; and a sustaining period for causing sustaining discharge in the discharge cell where the writing discharge has been caused, the initializing period of at least one of the plurality of subfields includes: an all-cell initializing operation for applying initializing voltage, the initializing voltage causing initializing discharge in all discharge cells for displaying an image; the initializing period of at least another one of the plurality of subfields includes: a selection initializing operation for selectively causing initializing discharge in a discharge cell where the sustaining discharge has been caused in the last subfield, and the number of subfields in the one field having the initializing period including the all-cell initializing operation is controlled based on the accumulated time.
