| 摘要 |
A plasma display apparatus comprises a Plasma Display Panel (PDP) (CP), an energy storage part (20) for recovering energy from the PDP, and an energy supply and recovery controller (30) that forms a current path so that the energy storage part (20) can be charged or discharged (S1, S2). 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.
