Abstract:
A method of driving a coplanar-type plasma display panel comprising:a first plate provided at least with a first array of electrodes, a second plate, parallel to the first, provided at least with a second array of pairs of electrodes, the overall direction of which is approximately orthogonal to that of the electrodes of the first array, the electrodes of each pair leaving between them discharge regions positioned at the intersections of the electrodes of the first array and of the pairs of electrodes of the second array, said method comprising the application of at least one series of sustain voltage pulses so as to generate sustain discharges in each of the intersection regions in which it is desired to sustain a discharge, and after at least one of said pulses generating a sustain discharge, the application, between the two electrodes of a pair crossing said region, of a pulse train with a frequency high enough to stabilize said discharge, wherein: said sustain voltage pulses are applied between one of the electrodes of said pair and the electrode of the first plate crossing said region; in each discharge region of the panel, the distance separating the electrodes of a pair is greater than the distance separating the electrode of the first plate crossing said region and the electrode of said pair between which said sustain voltage pulses are applied.
