Plasma display apparatus and driving method thereof

A plasma display apparatus comprises:

• a plasma display panel comprising a scan electrode and a sustain electrode;
• a first energy supply unit for supplying a first energy corresponding to a first voltage by means of resonance, and supplying a first sustain voltage, followed by recovering the first energy by means of resonance;
• a second energy supply unit for supplying a second energy corresponding to a second voltage having an opposite polarity to the first voltage by means of resonance, and supplying a second sustain voltage having an opposite polarity to the first sustain voltage, followed by recovering the second energy by means of resonance;
• a first voltage sustain unit for applying the first sustain voltage or a ground level of a voltage;
• a second voltage sustain uint for applying the second sustain voltage or a ground level of a voltage;
• and
• a path forming unit which serves to supply the first energy to the scan electrode and supply the second energy to the sustain electrode;
• serves to supply the first sustain voltage from at least one of the first energy supply unit and the first voltage sustain unit to the scan electrode and simultaneously supply the second sustain voltage from at least one of the second energy supply unit and the second voltage sustain unit to the sustain electrode;
