Patent ID: 7642993

Claim:
A method for driving a plasma display panel having a plurality of first electrodes, a plurality of second electrodes, and a plurality of third electrodes extending in a direction crossing the first and second electrodes while one frame is divided into a plurality of subfields, the method comprising: dividing the plurality of first electrodes into a plurality of groups comprising a first group and a second group, the plurality of second electrodes being biased at a first voltage during a reset period, an address period, and a sustain period; and during the address period: selectively applying a second voltage to the first group of the plurality of first electrodes, the second voltage for selecting discharge cells among a plurality of discharge cells coupled to the first group; and selectively applying a third voltage lower than the second voltage to the second group of the plurality of first electrodes, the third voltage for selecting discharge cells among a plurality of discharge cells coupled to the second group.
