ABSTRACT:
A gas discharge display device for exhibiting an analog value in a sealed envelope having a viewing window with a plurality of linear cathode segments arranged in succession to form a row or column capable of exhibiting a glow discharge. The cathodes are arranged in groups within the sealed envelope with a separate anode electrode in operative relationship with each of the groups of cathodes. Alternate ones of the anode electrodes are activated simultaneously in alternating sequence, so that the time duration of cathode glow exhibited on each cathode segment is increased to provide a significant increase in the intensity of the bar graph display. The intensity of the bar graph may be decreased to accommodate a surrounding environment by reducing the on time for each cathode segment.
