Patent ID: 7619588

Claim:
A plasma display device comprising: a plurality of scan electrodes in a first direction; a plurality of sustain electrodes the first direction; a plurality of address electrodes in a second direction that is substantially perpendicular to the first direction; a plurality of cells, each cell having corresponding scan, sustain and address electrodes, a first driving circuit configured to drive the plurality of scan electrodes; a second driving circuit configured to drive the plurality of sustain electrodes; and a third driving circuit configured to drive the plurality of address electrodes, wherein a plurality of sub-fields are used for providing gray scale, and during an address period of at least one sub-field, a scan waveform is provided to at least one scan electrode by the first driving circuit, and during the address period, address waveforms to select at least one cell receiving the scan waveform are provided to the plurality of address electrodes by the third driving circuit, wherein all start timings of the address waveforms during the address period are offset from a start timing, during the address period, of the scan waveform corresponding to the address waveforms and the at least one sub-field includes a pre-reset period prior to a reset period, and wherein a negative voltage is provided to the scan electrode in the pre-reset period and a positive voltage is provided to the sustain electrode in the pre-reset period.
