Abstract
A technique capable of suppressing or preventing generation of flickers (blinks) by a sustain period control as well as capable of ensuring or enhancing display quality in a PDP device. The PDP device adjusts a sustain pulse of the sustain period for every subfield by selecting a combination of one or more than one cycle so that start and end timings of a field in fields before and after change are almost the same according to a display load ratio of the subfield of the field. Field weighted emission center positions then becomes almost the same, and flickers and the like are suppressed.
