Patent ID: 7576709

Claim:
A method for driving a plasma display panel having a plurality of first electrodes and second electrodes in parallel on a first substrate, and a plurality of address electrodes crossing the first electrodes and the second electrodes on a second substrate, wherein a first electrode of the first electrodes, a second electrode of the second electrodes, and an address electrode of the address electrodes form a discharge cell of a plurality of discharge cells, the method comprising: gradually reducing a voltage at the first electrode from a first voltage to a second voltage during a reset period; applying a third voltage to the first electrode and applying a fourth voltage to the address electrode of the discharge cell to be selected from among the plurality of discharge cells, during an address period; and sustain discharging the discharge cell selected in the address period, during a sustain period, wherein the second voltage is less than a negative value of 80% of a difference between voltages applied to the first electrode for the sustain discharging in the sustain period.
