Abstract
A method of driving a plasma display device that includes a plurality of scanning electrodes, a plurality of sustaining electrodes, and a plurality of data electrodes is such that, when m is any given integer, the data electrodes are applied with a negative polarity pulse when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if a final pulse in a sustain period of an (m−1)-th subfield is applied to the scanning electrodes and an m-th subfield includes an initialization period. If the final pulse in the sustain period of the (m−1)-th subfield is applied to the sustaining electrodes and the m-th subfield includes the initialization period, the data electrodes are applied with a positive polarity pulse when a voltage applied to the scanning electrodes gradually increases during the initialization period.
