Abstract:
1. A method for driving a plasma display panel including a plurality of first electrodes and second electrodes in parallel on a first substrate, and a plurality of third electrodes crossing the first electrodes and second electrodes and being on a second substrate, wherein a plurality of discharge cells is formed by first electrodes, second electrodes, and third electrodes, and wherein a single subfield includes an address period for forming wall charges at a discharge cell to be selected from among the discharge cells, and a sustain period for discharging the selected cell, the method comprising: in the sustain period: applying a first pulse to a second electrode of the plurality of second electrodes while a first electrode of the plurality of first electrodes is established at a first voltage; and alternately applying to the first electrodes and the second electrodes a sustain pulse with a second voltage defined by a voltage difference between the first electrodes and the second electrodes, wherein the second voltage is less than a voltage difference between the first pulse and the first voltage.
