Patent ID: 7872615

Claim:
A method for driving a plasma display panel that includes a plurality of address electrodes, a plurality of scan electrodes and sustain electrodes alternately arranged in pairs, and a panel capacitor formed among the address electrode, the scan electrode and the sustain electrode, the method comprising steps of: (a) storing energy in a first inductor coupled to one terminal of the panel capacitor and at least one second inductor coupled to the other terminal of the panel capacitor, while the one terminal of the panel capacitor is sustained at a level of a summation of a first voltage and a second voltage and the other terminal of the panel capacitor is sustained at a third voltage; (b) applying the third voltage to the one terminal of the panel capacitor and the summation of the first voltage and the second voltage to the other terminal of the panel capacitor using the energy stored in the first and second inductors; (c) sustaining the other terminal of the panel capacitor at the summation of the first and second voltages, and recovering the energy stored in the first inductor and the second inductor through a first capacitor coupled to the other terminal of the panel capacitor and charged to the second voltage and a first power source for supplying the first voltage; and (d) storing energy in the first inductor and the second inductor, while the one terminal of the panel capacitor is sustained at the third voltage and the other terminal of the panel capacitor is sustained at the summation of the first voltage and the second voltage.
