Abstract
A method for driving a plasma display having discharge regions each crossed by a pair of sustain electrodes (YS, YAS) and at least one trigger electrode (XA) 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 VS between the electrodes of each pair of sustain electrodes serving these regions, and the application of a trigger pulse VM, of duration τM less than 1 μS, between the trigger electrode (XA) 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.
