Patent ID: 7170474

Claim:
A device for driving a plasma display panel on which first electrodes and second electrodes are formed, a capacitive load being formed by the first electrode and the second electrode, the device comprising: at least one inductor having a first terminal coupled to the first electrode; a capacitor coupled to a second terminal of the inductor; at least one first switch coupled between the inductor and the capacitor or between the inductor and the first electrode, charging or discharging the capacitive load by a resonance of the capacitive load and the inductor by being turned on, and forming a first current path allowing a first energy to be discharged from the capacitor and a second current path allowing a second energy greater than the first energy to be charged in the capacitor; and a second switch applying a first voltage to the first electrode after the capacitive load is charged by being turned on, wherein the second energy includes an energy discharged from the capacitive load by the resonance of the capacitive load and the inductor, and the first energy includes an energy for charging the capacitive load by the resonance of the capacitive load and the inductor.
