Abstract:
1. A plasma display apparatus comprising: a plasma display panel including a first scan electrode group and a second scan electrode group; a voltage supply unit that supplies a scan bias voltage and a scan voltage; a first charge delay unit and a second charge delay unit that receive the scan bias voltage from the voltage supply unit and supply the scan bias voltage to the first scan electrode group and the second scan electrode group; a first scan signal supply unit that receives the scan voltage from the voltage supply unit, supplies a scan signal, of which a lowest voltage is the scan voltage, to one scan electrode belonging to the first scan electrode group, and allows the other scan electrodes of the first scan electrode group to be floated; a second scan signal supply unit that receives the scan voltage from the voltage supply unit, supplies a scan signal, of which a lowest voltage is the scan voltage, to one scan electrode belonging to the second scan electrode group, and allows the other scan electrodes of the second scan electrode group to be floated; and a first voltage return unit and a second voltage return unit that supply the scan bias voltage to the scan electrodes to which the scan signal is supplied.
