ABSTRACT:
Method comprising a succession of image frames which each comprise a sustain phase of the display discharge regions which itself comprises the application of sustain voltage pulses VSbetween the electrodes of each pair crossing these regions, and, during each sustain pulse, the application of trigger voltage pulses VMto groups of discharge regions, which pulses are applied successively and not simultaneously to the various groups of discharge regions.Thanks to the application in stages of the trigger pulses during each sustain pulse, a reduction in the instantaneous current required to supply the display is obtained.
