Abstract:
1. A device for driving a plasma display panel having a plurality of address electrodes, scan electrodes, sustain electrodes, and panel capacitors each formed between the address, scan, and sustain electrodes, comprising: first and second inductors coupled to the panel capacitor; first and second signal lines for respectively transmitting first and second voltages; a capacitor for charging a third voltage; a first current path formed between the first signal line and the capacitor so that a current in the first direction is supplied to the first inductor to store a first energy, while the voltage at the panel capacitor is maintained to be the first voltage; a second current path for generating resonance between the first inductor and the panel capacitor, and using the first energy and the resonance to reduce the voltage at the panel capacitor to the second voltage, while the first energy is stored in the first inductor; a third current path for recovering the energy remaining in the first inductor while the voltage at the panel capacitor is changed to the second voltage; a fourth current path formed between the capacitor and the second signal line so that a current in the second direction opposite the first direction may be supplied to the second inductor to store a second energy, while the voltage at the panel capacitor is maintained to be the second voltage; a fifth current path for generating resonance between the second inductor and the panel capacitor, and using the second energy and the resonance to increase the voltage at the panel capacitor to the first voltage, while the second energy is stored in the second inductor; and a sixth current path for recovering the energy remaining in the second inductor while the voltage at the panel capacitor is changed to the first voltage.
