Abstract:
Display apparatus comprises d.c. gas discharge display cells with a sustaining potential thereacross comprising a pulse train with pulse amplitude, pulse duration and pulse spacing such that an ignited cell is reignited upon application of each sustaining pulse and an extinguished cell remains extinguished upon application of the sustaining pulses unless ignited or extinguished by external means.
Abstract:
A gas discharge display panel including reservoir cells for providing ionizable gas and a plurality of gas discharge display memory cells. Included are a plurality of addressing electrodes each having a plurality of apertures therethrough, the electrodes being arranged in superposed configuration so that the apertures align to form gas conductive channels extending from the reservoir cells to the display memory cells. The addressing electrodes are adapted for connection to sources of selectable electrical potential whereby gas discharge columns are extended from the reservoir cells through selected channels thereby igniting gas discharges in selected display memory cells.
Abstract:
A digitally addressable gas discharge display including a reservoir for providing ionizable gas and a plurality of gas discharge display cells. The device includes a plurality of addressing electrodes each having a plurality of apertures therethrough. The addressing electrodes are arranged in stacked configuration so that the apertures are aligned to form gas conductive channels extending from the reservoir to the display cells, respectively. The addressing electrodes are adapted for selective connection to sources of electrical potential whereby gas discharge columns are extended from the reservoir through selected channels thereby igniting gas discharges in selected display cells.
