Patent ID: 8085221

Claim:
A method of driving a plasma display panel provided with a plurality of discharge cells, each discharge cell having a display electrode pair formed of a scan electrode and a sustain electrode, one field of the plasma display comprising a plurality of subfields with each subfield having an addressing period for producing an address discharge selectively in any of the discharge cells, and a sustaining period for producing a sustain discharge by applying a number of sustaining pulses corresponding to a weight of brightness in the discharge cell where the address discharge has been produced, the method comprising the steps of: driving a rise or a fall of sustaining pulses by producing a resonance between an inter-electrode capacitance of a display electrode pair and an inductor; clamping a voltage of the sustaining pulses at a predetermined potential; setting a time of the sustaining pulses so that twice a time of driving the rise of the sustaining pulses becomes equal to or longer than a duration of the sustaining pulses; and setting a resonance cycle of the inter-electrode capacitance of the display electrode pair and the inductor to be twice or longer than the time of driving the rise of the sustaining pulses.
