Abstract
Abstract A gas panel display device having a micropanel disposed between first and second sets of electrical grid wires has one set of grid wires oriented orthogonally to the other set with the crossover points defining coordinate intersections. The micropanel is composed of a sealed envelope which is evacuated and filled with an illuminable gas under less than atmospheric pressure, and a nonmetallic spacer or mesh is enclosed within the envelope. The gas in the regions of the coordinate intersections define gas cells which may be selectively illuminated by electrical signals on the grid wires.
