Abstract

A method of driving a plasma display panel having plural, parallel sustain and scan electrodes, corresponding to respective display lines, and plural address electrodes in opposed relationship and electrically isolated with respect to the sustain and scan electrodes and intersecting same so as to form respective discharge cells at the intersections. The method produces an interlaced display by generating discharges in selected discharge cells, in odd and even fields, between respective, different sets of the sustain and scan electrodes. Each of the odd and even fields includes a reset period in which a reset discharges are produced in the discharge cells to establish a uniform charge distribution therein, an address period in which write discharges are produced in selected discharge cells in accordance with display data and a sustain discharge period in which sustain discharge pulses are produced in the written discharge cells to establish a glow discharge, for display during the respective periods. Potential differences between the respective sets of the sustain and scan electrodes of the odd and even fields are held below a discharge initiating voltage level, thereby avoiding the otherwise occurring problem of contrast drop.
