Bargraph display

A gas analog display panel comprising:

• a substrate having a front surface;
• a plurality of continuous electrode wires wound around said substrate in alternating sequence, each turn of each of said plurality of wires around said substrate having a portion adjacent said front surface of said substrate, each of said turns being in alternating sequence with a turn of another of said wires to form a ladder array of said portions, each of said portions of an individual wire of each of said plurality of wires being electrically interconnected by the winding configuration of each of said plurality of wires around said substrate;
• second electrode means positioned in operative relation to said electrode wires;
• a transparent cover sealed to said substrate to form an envelope over said front surface of said substrate;
• and
• an ionizable gas contained in said envelope, to provide a glow discharge between said second electrode and any one of said wires for transfer along said ladder array by external electrical potential means connected to said second electrode and said wires to apply electrical potential in repeating sequence to said plurality of wires, said substrate has an elongated recessed channel within said front surface and wherein said second electrode means is positioned within said channel, said channel forming the glow discharge chamber.
