Abstract:
1. A method for driving a plasma display panel that includes; first and second substrates disposed opposite to each other, a plurality of scanning electrodes and a plurality of sustaining electrodes which extend in a first direction and are alternately disposed on such a side surface of said first substrate that faces said second substrates, and a plurality of data electrodes which extends in a second direction perpendicular to said first direction and is disposed on such a side surface of said second substrate that faces said first substrate, in such a configuration that a display cell is disposed at each of intersections between said scanning and sustaining electrodes and said data electrodes, to produce a display which corresponds to a video signal, said method comprising the steps of: giving negative wall charge on said scanning electrodes and positive wall charge on said sustaining electrodes and said data electrodes; adjusting an amount of the negative wall charge on said scanning electrodes, an amount of the positive wall charge on said sustaining electrodes, and an amount of the positive wall charge on said data electrodes; setting a potential of said scanning electrodes to a positive constant value; and sequentially applying to said scanning electrodes a scanning pulse having a voltage lower than said constant value and also applying a rising data pulse to said data electrodes based on said video signal, to thereby generate write-in discharge selectively, wherein relationships of: are established, where (Vs, pe) indicates a final arrival potential of said scanning electrodes in said wall-charge amount adjusting step, Vc
