Patent ID: 8305402

Claim:
A plasma display device comprising: a plasma display panel (PDP) including an upper substrate, a lower substrate, a plurality of scan electrodes and a plurality of sustain electrodes formed on the upper substrate, and a plurality of address electrodes formed on the lower substrate; and a driver applying driving signals to the plurality of electrodes, wherein a reset discharge occurs in a part of discharge cells of a plurality of discharge cells, and wherein at least one of a plurality of subfields of a frame includes a setup period for applying a first reset signal whose level gradually increases from a first voltage to a second voltage to the plurality of scan electrodes, and during the setup period a third voltage is supplied to address electrodes corresponding to the part of discharge cells, and a fourth voltage, which is a positive higher voltage than the third voltage, is supplied to the other address electrodes of the plurality of address electrodes so as not to cause the reset discharge.
