ABSTRACT:
The display panel comprises a gas-filled envelope containing an array of line-like glow cathodes. Circuit means is coupled to the panel to scan the array of cathodes and to energize a number of cathodes determined by the magnitude of an input analog signal. The cathodes which are energized at any instant, display a bar of light. A light source is provided behind the panel to transmit light through the panel and between the line-like cathodes so that a viewer sees both a bar of cathode glow light, the length of which is determined by the analog signal, and a bar of light generated by the light source, the length of which is determined by the number of cathodes which are not energized and do not generate cathode glow.
