Patent ID: 7576710

Claim:
A plasma display device for receiving external image data, and displaying the image data during a plurality of subfields, each of the subfields comprising at least a reset period and an address period, the plasma display device comprising: a plasma panel including a plurality of address electrodes, scan electrodes, sustain electrodes and discharge cells; a controller for receiving the image data and generating and outputting scan electrode driving signals, sustain electrode driving signals, and address electrode driving signals, the sustain electrode driving signals being set so that a potential of the sustain electrodes becomes less than a first voltage applied during the reset period by a predefined voltage during the address period of a subfield with a minimum weight from among the plurality of subfields; an address data driver for applying a voltage corresponding to the address electrode driving signals to the address electrodes for selecting discharge cells to be discharged from among the discharge cells; a sustain electrode driver for applying a voltage corresponding to the sustain electrode driving signals to the sustain electrodes; and a scan electrode driver for applying a voltage corresponding to the scan electrode driving signals to the scan electrodes.
