Plasma display panel driving method, plasma display panel driving circuit, and plasma display device

A plasma display panel driving circuit for causing such a plasma display panel to give display which corresponds to a video signal that includes first and second substrates disposed opposite to each other, a plurality of scanning electrodes and a plurality of sustain ing 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, said circuit comprising a controller for:

• 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:
• (Vd, pe)−(Vs, pe)<(Vd, w)−(Vs, w);
• andVc1≦Vc2
• are established, where (Vs, pe) indicates a final arrival potential of said scanning electrodes in said wall-charge amount adjusting step, Vc1 indicates a potential of said sustaining electrodes, (Vd, pe) indicates a potential of said data electrodes, (Vs, w) indicates a potential of said scanning pulse, (Vd, w) indicates a potential of said data electrode in the display cell to which said data pulse is not applied even when said scanning pulse is applied on the basis of said video signal, and Vc2 indicates a potential of said sustaining electrodes in said step of applying said scanning pulse and said data pulse.
