Very fast method of control by semi-selective and selective addressing of a coplanar sustaining AC type of plasma panel

A method for the control of a coplanar sustaining AC plasma panel, said panel comprising column electrodes intersecting with two classes of parallel electrodes, the first class of electrodes being formed by addressing-sustaining electrodes and the second class being formed by solely sustaining electrodes, each addressing-sustaining electrode forming, with a neighboring solely sustaining electrode, a pair of sustaining electrodes, each pair of electrodes corresponding to a row of pixels perpendicular to the column electrodes, the pixels being formed substantially at each intersection of a column electrode with a pair of electrodes, said method consisting in the application of first sets of pulses of cyclical voltages to all the addressing-sustaining electrodes and in applying second sets of pulses of cyclical voltages to all the solely sustaining electrodes, the two sets of voltage pulses having a same period within which said pulses of voltages develop, between the electrodes of each pixel, voltage differences which firstly, in a given time interval, create a phase designed for a control of pixels by semi-selective addressing and, in another time interval, generate a second phase designed for a control of pixels by selective addressing and, secondly, generate sustaining discharges, a method wherein, simultaneously, certain pixels are controlled by semi-selective addressing and other pixels are controlled by selective addressing.
