Abstract:
1. A method of driving a plasma display device including a plurality of first electrodes and a plurality of second electrodes, the first and second electrodes forming panel capacitors of the display, the method comprising: during a first period of an address period, applying a first voltage to the plurality of first electrodes through a first switch and an inductor connected between a first power source for supplying the first voltage to the plurality of first electrodes; sequentially applying a scan pulse to the plurality of second electrodes during the first period; applying a second voltage during the first period to second electrodes that are not receiving the scan pulse during the first period; applying a third voltage that is higher than the second voltage through a second switch, the second switch connected between the second electrodes and a second power source for supplying the second voltage to the plurality of second electrodes during a second period of the address period, wherein the second period is consecutive to the first period; and turning off the first switch when a resonance current in the inductor has a value other than a maximum value during the second period of the address period.
