Abstract:
1. A method for driving a plasma display device displaying varying video images using a plurality of discharge cells defined by a plurality of first electrodes, a plurality of second electrodes, and a plurality of third electrodes intersecting the first and second electrodes, comprising: initializing the plurality of discharge cells; selecting light-emission cells from among the plurality of discharge cells; and discharging the light-emission cells by supplying the first electrodes corresponding to the light-emission cells with first sustain pulses whose periods are irregular and supplying the second electrodes with second sustain pulses whose periods are irregular and which are alternative to the first sustain pulses, with at least one pair of the first sustain pulses having different periods, and at least one pair of the second sustain pulses having different periods, with a rising period of a sustain pulse supplied to one of the first and second electrodes at least partially overlapping a falling period of a sustain pulse supplied to the other one of the first and second electrodes, with a maintaining period for maintaining a low level voltage of the first sustain pulse partially overlapping a maintaining period for maintaining a low level voltage of the second sustain pulse, and with the overlapped period being equal to the overlapped period between the rising period of the sustain pulse supplied to one of the first and second electrodes and the falling period of the sustain pulse being supplied to the other one of the first and second electrodes.
