Abstract
During a sustain period of a plasma display device, voltages of Vs and 0V are alternately applied to a plurality of scan electrodes. At this time, by applying Vs to a first node, a first capacitor with a first terminal coupled to the first node is charged with a first voltage. By then applying 0V to the first node, a second capacitor with a first terminal is coupled to a second node with a voltage of a second terminal of the first capacitor is charged with a second voltage. In an address period, a voltage of the second node is selectively applied to a plurality of scan electrodes. Therefore, an additional power source for supplying a voltage to selectively apply to a plurality of scan electrodes in an address period is not necessary.
