Patent ID: 7167144

Claim:
Method for driving an AC image-display plasma panel with coplanar sustain discharges, and with memory effect, the said panel comprising: a front tile and a rear tile, which are parallel and provide between them a space filled with a discharge gas; one of the tiles comprising at least a first array of electrodes and the other tile comprising at least a second array of triads of electrodes, the general direction of which is approximately orthogonal to that of the electrodes of the first array; each triad comprising two opposed lateral electrodes and one central electrode; the spaces located at the intersections of the electrodes of the first array with the triads of electrodes of the second electrode array forming a matrix of light-discharge regions and of dots of the image to be displayed; the electrodes of the triads being coated with a dielectric layer; the said method comprising at least one sustain operation by applying a series of sustain voltage pulses between the electrodes of each triad so as to generate sustain discharges in each of the intersection regions in which it is desired to sustain a light discharge; wherein, during the said sustain operation, the central electrodes of each of the said triads always act as anode; wherein before or after each sustain operation, a selective addressing or erasing operation is applied only in each of the said intersection regions in which it is desired to sustain a light discharge during the said series, by applying at least one voltage pulse between the electrode of the said first array crossing the intersection region and the central electrode of the triad crossing the intersection region; and wherein, all of the regions supplied via the same triad forming one row of the panel, on any two adjacent rows through which a first triad on the one hand and a second triad on the other hand pass respectively, the lateral electrode of the first triad is electrically connected to the same potential as the closest lateral electrode of the second triad.
