Abstract:
1. A plasma display device comprising: a plasma display panel (PDP) having scan electrodes and sustain electrodes to form a plurality of electrode pairs; and a first driving circuit configured to successively apply a first signal and a second signal to the scan electrodes before an address period of at least one sub-field, wherein the first signal comprises an initialing pulse rising to a first maximum voltage value and a first decreasing pulse falling to a first minimum voltage value, the second signal comprises an enhancing pulse rising to a second maximum voltage value that is less than the first maximum voltage value and a second decreasing pulse falling to a second minimum voltage value that is greater than the first minimum voltage value, and the second maximum voltage value is equal to a sustain voltage applied to the scan electrodes or applied to the sustain electrodes in a sustain period of the at least one sub-field.
