Abstract
A method for driving a plasma display having discharge regions each crossed by a pair of sustain electrodes (Y.sub.S, Y.sub.AS) and at least one trigger electrode (X.sub.A) is disclosed. The method includes a succession of image frames or subframes which each have a discharge region sustain phase including the application of voltage pulses V.sub.S between the electrodes of each pair of sustain electrodes serving these regions, and the application of a trigger pulse V.sub.M, of duration .tau..sub.M less than 1 .mu.S, between the trigger electrode (X.sub.A) and one and/or the other of the electrodes of each pair serving these regions. The intensity and luminous efficiency of plasma displays can thus be significantly improved.
