Abstract
A drive system for an alternating current (AC) driven type gas discharge panel in which either one of the electrode pitches of X and Y electrodes is made smaller than the other. A positive pulse voltage is applied to the electrodes of the smaller electrode pitch and a negative pulse voltage is applied to the electrodes of the larger electrode pitch, thereby to write information in a selected discharge point. The AC driven type gas discharge panel of an electrode arrangement of an asymmetrical electrode pitch is driven with a maximum write margin which does not cause half select misfire.
