Abstract
A control process for addressing an AC plasma panel. The panel includes line electrodes crossed with column electrodes where the intersections of these electrodes define cells. Sustain signals are applied to all of the line electrodes by way of at least one control circuit. The cells are addressed by superimposing supplementary voltage porches onto the sustain signals and then subsequently superimposing addresses pulses onto the supplementary porches. This method makes it possible to reduce the amplitude of the addressing pulses, thus resulting in a lesser demand on the control circuits resulting in a reduction of capacitive consumption.
