Patent ID: 7078866

Claim:
A plasma display panel including sustain means for providing energy to electrodes related to selected cells to effect discharge in the selected cells, and a panel capacitor, wherein the sustain means 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 and is opened when the inductor is substantially fully charged; panel capacitor charge path means which provides a path through which the panel capacitor is charged with the energy charged in the inductor and is opened when the panel capacitor is substantially fully charged; panel capacitor discharge path means which provides a path through which the panel capacitor is discharged and is opened when the panel capacitor is substantially fully 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, and performs selective driving during gas discharge of the panel, 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.
