Patent ID: 8207912

Claim:
A driving method for a plasma display panel in which sustain pulses are alternately applied to a pair of display electrodes of plural discharge cells provided in the plasma display panel to generate a sustain discharge, thereby causing an image to be displayed on the plasma display panel, wherein the sustain pulses include a one-crest discharge voltage waveform having one voltage peak that generates a discharge once by applying one pulse and a two-crests discharge voltage waveform having a first maximum value and a second maximum value that generates discharges twice by applying one pulse, the second maximum value being clamped to a predetermined voltage smaller than the first maximum value, the driving method comprising: consecutively applying a predetermined number of the sustain pulses of two-crests discharge voltage waveforms, after applying the sustain pulse of one-crest discharge waveform to the pair of display electrodes, the sustain pulse of one-crest discharge waveform being applied to the pair of display electrodes for every predetermined number of applications of the sustain pulses of two-crests discharge voltage waveform to the pair of display electrodes; and making a second time period, which is from a start of applying a second sustain pulse of two-crests discharge voltage waveform until a voltage of the second sustain pulse is clamped to the second maximum value, longer than a first time period, from a start of applying a first sustain pulse of two-crests discharge voltage waveform until a voltage of the first sustain pulse is clamped to the second maximum value in any two consecutive sustain pulses of two-crests discharge voltage waveform.
