ABSTRACT:
The present invention relates to a plasma display apparatus and driving method thereof. The plasma display apparatus according to the present invention comprises a Plasma Display Panel (PDP), an energy storage part for recovering energy from the PDP, and an energy supply and recovery controller that forms a current path so that the energy storage part can be charged or discharged. In the energy supply and recovery controller, a reference bias voltage is a negative voltage. The driving method of the plasma display apparatus according to the present invention comprises the steps of supplying energy to the PDP, and maintaining a reference bias voltage of a recovery switch part to a negative voltage when an energy storage part recovers energy from the PDP.
