Patent ID: 7492331

Claim:
A plasma display panel (PDP) for generating input video signals into a plurality of subfields, and for dividing each subfield into a reset period, an address period, and a sustain period, the PDP comprising: an address electrode; a scan electrode; a sustain electrode arranged in a pair with the scan electrode; a controller for generating subfield data and sustain pulse information and outputting a floating control signal for controlling a floating time of the scan electrode according to the sustain pulse information; and a driver for applying a voltage that corresponds to subfield data of the address electrode, applying a voltage to the sustain electrode and the scan electrode according to sustain pulse information, and floating the scan electrode according to the floating control signal, wherein the controller controls the floating time to be reduced when a number of sustain pulses of a previous subfield is increased, and wherein the driver drives the scan electrode so that floating the scan electrode during the floating time after changing a voltage of the scan electrode is repeated a predetermined number of times in the reset period.
