Abstract
An energy recovery circuit of a plasma display panel and a drive method thereof are disclosed. A plasma display panel according to the present invention comprises an inductor for charging or discharging the panel capacitor, inductor charge path means which provides a path through which energy is charged to the inductor, panel capacitor charge path means which provides a path through which the panel capacitor is charged with the energy charged in the inductor, panel capacitor discharge path means which provides a path through which the panel capacitor is discharged, auxiliary storage means which stores energy if the substantially fully discharged state of the panel capacitor is maintained and supplies the energy to the panel capacitor if the substantially fully charged state of the panel capacitor is maintained, and potential sustain means connected to the inductor and the panel capacitor, wherein the potential sustain means includes switch means connected between the auxiliary storage means and the panel capacitor and another switch means connected between a ground potential and the panel capacitor.
