The address pulse has a first voltage and a second voltage. The scan pulse has a third voltage and a fourth voltage.

Abstract: A plasma display including a PDP and a driving method. High PDP temperatures and high load ratios impair the sustain discharge operation by creating uncontrollable charges that create a weak discharge during the address period. Subfields are rearranged to place a subfield having a weight lower than a reference weight between subfields having weights greater than the reference weight when the temperature of the PDP exceeds a reference temperature. The load ratio of at least one subfield is detected from an input video signal of one frame, and the subfields are rearranged when either the detected temperature is greater than the reference temperature or the detected load ratio is greater than a reference load ratio, or both. Uncontrollable charges are hence maintained below a threshold level and the weak discharge is reduced.
