Abstract
A 3-electrode, surface-discharge type plasma display is capable of offsetting a radiation fields which is generated at the time of displaying, to reduce radiation noises. To drive the plasma display, an X-electrode and a Y-electrode are separated to an even number (2m) and an odd number (2m-1), respectively. During a resetting period and an addressing period, pulse voltage is applied to the even-numbered and odd-numbered electrodes at the same time, whereas in a sustained discharge period, the phase of the pulse voltage applied to the even-numbered electrode is delayed by 180 degrees from that applied to the odd-numbered electrode.
