Abstract
A gas discharge display/memory device in which the driving circuitry is coupled to the panel electrodes through a plurality of gas discharge cells. Along one edge of each of the panel electrode arrays, there are formed a plurality of gas discharge shift cells each defined by a pair of crosspoints, one crosspoint formed by one of a plurality of shift electrodes and a common electrode means and the other crosspoint formed by the common electrode means and one of the panel electrodes. The shift electrodes associated with each electrode array are connected to individual shift voltage generators which generate phased shift voltages to shift a discharge along the common electrode. The discharge associated with each electrode array can be transferred to a selected panel electrode by applying a transfer pulse voltage to the electrodes forming the second crosspoint such that a discharge is initiated in the panel cell defined by the crosspoint of the selected panel electrodes. A sustainer generator is connected to both electrode arrays through a plurality of gas discharge sustainer cells defined by the crosspoints formed by a sustainer electrode and all of the panel electrodes of one of the …
