A display device comprises groups of scan electrodes (X1, X2) and groups of sustain electrodes (Y1-Y2) forming groups of electrode pairs (X1-Y1, X1-Y2, X2-Y1, X2-Y2). The sustain discharge for at least one of these groups occur at a different time than for at least one other group. The currents during sustain discharge are then distributed in time, reducing the peak heights and reducing losses and stray electromagnetic radiation.
