Abstract:
1. A plasma display panel comprising: a data electrode drive unit applying a data pulse to a data electrode; a scan electrode drive unit provided with a plurality of switching circuits for allowing a current to flow through a first scan electrode but not to flow through a second scan electrode when a scan pulse is applied to correspond to the data pulse applied by the data electrode drive unit, wherein the plurality of switching circuits includes a first switch to control the supply of current through the first scan electrode when selected and to block the flow of current through the first scan electrode when unselected; and a ground diode arranged between the first switch and a ground switch device, the ground diode to allow the first scan electrode to receive the scan pulse when the ground switch device is turned on, the second scan electrode to assume substantially a ground level when the ground switch device is turned on, wherein each of the plurality of the switching circuits comprises only one switching device to apply the scan pulse per one scan electrode, the only one switching device for the first scan electrode corresponding to the first switch.
