Abstract:
1. A plasma display apparatus comprising: a plasma display panel comprising a first electrode and a second electrode; and a driver for supplying a first pulse having a negative polarity to the first electrode during a pre-reset period before a reset period of a first subfield among a plurality of subfields for representing an image, and supplying a second pulse having a positive polarity to the second electrode while the first pulse is supplied to the first electrode, supplying a sustain pulse to the second electrode in a sustain period after the reset period of the first subfield, and supplying a ground level voltage to the first electrode throughout the sustain period of the first subfield, wherein a grey level of light generated during an address period of the first subfield is twice as high as a grey level of light generated by the first and second pulses supplied during the pre-reset period before the reset period of the first subfield, and wherein a grey level of light generated during the sustain period is five times as high as a grey level of light generated by the first and second pulses supplied during the pre-reset period before the reset period of the first subfield.
