Patent ID: 7145582

Claim:
A method of driving a plasma display device in which a plurality of scanning electrodes and a plurality of sustaining electrodes are formed on a first substrate of a plasma display panel, and a plurality of data electrodes are formed on a second substrate of the plasma display panel, the first substrate and the second substrate being positioned so as to face each other, wherein if a rectangular pulse as a final pulse included in a sustain period of an (m−2)-th subfield among a plurality of subfields belonging to one field is applied to the scanning electrodes and an initialization period is included in an (m−1)-th subfield the data electrodes are applied with a negative polarity pulse at the same time when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if the rectangular pulse as a final pulse included in the sustain period of the (m−2)-th subfield is applied to the sustaining electrodes and the initialization period is included in the (m−1)-th subfield, the data electrodes are applied with a positive polarity pulse at the same time when a voltage applied to the scanning electrodes gradually increases during the initialization period, and m is any given integer.
