Abstract:
An apparatus for driving a plasma display panel including a plurality of address electrodes, a plurality of scan electrodes and sustain electrodes arranged in a zig-zag pattern so as to make pairs with each other, and a panel capacitor formed by the scan electrodes and the sustain electrodes, comprising:a sustain-discharge unit comprising first and second switches that are serially connected to each other between a power source to which a sustain-discharge voltage is applied and a ground, and whose contact point is connected to a first end of the panel capacitor, and third and fourth switches that are serially connected to each other between the power source and the ground, and whose contact point is connected to a second end of the panel capacitor; a first charge and discharge unit comprising a first inductor with a first end coupled to the first end of the panel capacitor, the first charge and discharge unit for increasing the voltage of the panel capacitor to the first sustain-discharge voltage using resonance of the first inductor and the panel capacitor; and a second charge and discharge unit comprising a second inductor with a first end coupled to the second end of the panel capacitor, the second charge and discharge unit for decreasing the voltage of the panel capacitor to the second sustain-discharge voltage using a resonance of the second inductor and the panel capacitor, wherein the sustain-discharge unit drives the first switch during the resonance of the first inductor to thus sustain the first sustain-discharge voltage, and drives the third switch during the resonance of the second inductor to thus sustain the second sustain-discharge voltage.
