ABSTRACT:
A plasma display device includes a plasma display panel having discharge cells formed between a plurality of first electrodes and a plurality of second electrodes and a driving circuit dividing one frame into a plurality of subfields, each subfield including a reset period, an address period, and a sustain period, and applying a driving voltage to the first electrodes and the second electrodes. During a sustain period of each subfield, a sustain discharge pulse is alternately applied to the first and second electrodes for triggering a sustain discharge. A width of a last sustain discharge pulse applied to the second electrode is set to be greater than a width of other sustain discharge pulses for selected subfields. The subfields may be selected based on whether a total number of the sustain discharge pulses during the sustain period is less than a critical number of sustain discharge pulses.
