Patent ID: 7355564

Claim:
A plasma display panel, comprising: a plurality of address electrodes, and corresponding pluralities of scan electrodes and sustain electrodes arranged in pairs; a controller adapted to accept external video signals and generate and output subfield data and sustain pulse information corresponding to the respective subfields, control voltage application such that a floating state for floating at least one electrode during a floating period and a voltage application state for changing a voltage of the at least one electrode during a voltage application period are repeatedly alternated such that the voltage of the at least one electrode is changed from a first voltage to a second voltage in the reset period, control the voltage application period or the floating period according to the subfield data, the subfield data comprising at least the number of addressed cells called for in previous subfield data, and output a control signal embodying the control of voltage application and the control of the voltage application time or floating time; an address data driver adapted to apply a voltage that corresponds to the subfield data to the address electrode; a sustain electrode driver adapted to apply sustain voltages to the sustain electrode according to the sustain pulse information output by the controller; and a scan electrode driver adapted to apply scan voltages to the scan electrode according to the sustain pulse information, wherein the controller is adapted to control the floating period such that the floating period is reduced when the number of addressed cells called for in the previous subfield data is increased.
