Abstract
Abstract A gas discharge display panel comprises a gas discharge shifting register for propagating glow discharges from stage to stage thereof in response to shifting signals. The apparatus includes a plurality of gas discharge display cells and electrode means interposed between the shifting register and the display cells and having a plurality of gas conductive channels therethrough extending from the stages of the shifting register to the display cells. The electrode means is selectively connectible to a source of addressing potentials generated in timed relation with respect to the shifting signals whereby gas discharge columns are selectively extended in the channels from the glowing stages of the shifting register to the display cells thereby igniting gas discharges in selected display cells.
