  • Publication number: 20060290610
    Abstract: A plasma display apparatus and a method of driving the plasma display apparatus are disclosed. The plasma display apparatus includes a plasma display panel including a scan electrode, a sustain voltage source, an inductor, an energy supply/recovery capacitor, and a maintenance capacitor. The inductor and the energy supply/recovery capacitor form a current path for supplying/recovering a sustain voltage to/from the plasma display panel, and for forming a current path for supplying/recovering one half of the sustain voltage to/from the plasma display panel. The maintenance capacitor forms a current path for maintaining a voltage of the plasma display panel at one half of the sustain voltage.
