ABSTRACT:
In a memory drive system of a DC type of plasma display panel, scan signals are applied to scan electrodes connected to the DC type of plasma display panel, with the scan signals each comprising a priming scan pulse for generating the priming discharge, a write scan pulse for generating the write discharge, and a sustain pulse train for generating the sustain discharge. The priming scan pulse, the write scan pulse and the sustain pulse train are sequentially shifted on a time basis for each scan signal. To each of the data electrodes connected to the DC type of plasma display panel, a data signal is applied in which, only when the write discharge is not to be generated, is a non-write pulse formed, which offers a turn-off level during an applying period of time for the write scan pulse, and which maintains a turn-on level when the write discharge is to be generated and during other periods of time except the applying period of time for the write scan pulse.
