Patent ID: 7612742

Claim:
A driving method of a plasma display device having a plurality of first electrodes, a plurality of second electrodes, and a plurality of third electrodes formed in a direction crossing a common direction of the first electrodes and the second electrodes, wherein a distance between the first electrodes and the second electrodes is greater than a distance between the first electrodes and the third electrodes, and wherein the plasma display device is driven during frames each divided into a plurality of subfields, each subfield including a reset period, an address period, and a sustain period, the driving method comprising, during the sustain period: applying a voltage falling from a first voltage to a second voltage to a second electrode while a third electrode is biased with the first voltage; after the application of the falling voltage, applying the second voltage to the second electrode for a predetermined period before applying a voltage rising from the second voltage to a third voltage to the second electrode; and applying a fourth voltage to the first electrode for generating a sustain discharge at a given point of the predetermined period.
