Abstract
There is provided a plasma display device using a driving device for supplying driving signals to a plasma display panel (PDP). In a sustain falling period that at least partially overlaps the rising period of reset signals supplied to scan electrodes formed on the PDP, a voltage supplied to sustain electrodes is gradually reduced and a positive polar voltage is supplied to address electrodes. In driving the PDP, gradually falling signals are supplied to the sustain electrodes in the rising period of the reset signals so that the driving margin of the PDP can be secured. The positive polar voltage is supplied to the address electrodes so that initialization discharge can be stably performed and that the erroneous discharge of the plasma display device can be reduced.
