Abstract:
1. An apparatus for driving a plasma display panel having a plurality of scan electrodes and sustain electrodes arranged in a zigzag pattern so as to make pairs with each other and having a panel capacitor between the scan electrodes and the sustain electrodes, the apparatus comprising: a sustain discharge unit having first and second switches serially connected between a first voltage and a second voltage and having a contact point of the first and second switches coupled to one end of the panel capacitor and third and fourth switches serially connected between the first voltage and the second voltage and having a contact point of the third and fourth switches coupled to the other end of the panel capacitor, the sustain discharge unit maintaining a voltage of a terminal of the panel capacitor at the first voltage or the second voltage; a first charge and discharge unit having first and second capacitors serially connected between the first voltage and the second voltage and a first inductor coupled to a contact point of the first and second capacitors and one end of the panel capacitor, the first charge and discharge unit charging one end of the panel capacitor to the first voltage or discharging it to the second voltage; and a second charge and discharge unit having third and fourth capacitors serially connected between the first voltage and the second voltage and a second inductor coupled to a contact point of the third and fourth capacitors and other end of the panel capacitor, the second charge and discharge unit charging the other end of the panel capacitor to the first voltage or discharging it to the second voltage.
