- 21 - GAS PLASMA DISPLAY Abstract Disclosed is an AC gas plasma display which provides the benefits of a planar display and permits a substantial separation of the write/erase and sustain function circuitry. First and second arrays of parallel electrodes (X1-X3, Y1-Y6) are disposed orthogonally on opposite surfaces within the gas envelope. One of the arrays includes a plurality of adjacent pairs of electrodes, e.g., Y3 and Y4, capable of sustaining glow discharges at the crosspoints of the two arrays. A desired area is illuminated or extinguished in a two-step sequence by applying appropriate pulses to selected electrodes in both arrays. For further separation of write/erase and sustain functions, one of the arrays can include a plurality of sets of three adjacent electrodes (Y1, Y2, Y3 of FIG. 10), with write/erase pulses applied to one of the electrodes and sustain pulses applied to the other two electrodes in the set.
