Abstract
A method for driving an AC type PDP is provided in which a display discharge is generated by a low voltage so that the power consumption can be reduced, and the light emission efficiency can be improved. A voltage pulse train Vi having alternating polarity is applied between the display electrodes so that the display discharge is generated at a time interval below 2 μ sec which space charge causes an active priming effect and that the polarity of the wall voltage between the display electrodes switches for every display discharge.
