DC Gas discharge displays with and without inherent memory

An experimental 40 × 100 dc gas discharge TV panel was described last year at the SID symposium at Los Angeles. A new 100 × 100 picture-element panel is under study in which more attention is given to the uniformity of the discharge characteristics to achieve a better gray scale. The electronic circuits are further integrated both for uniformity and reliability reasons. The cell density is 20 per inch. A new technology to build the panels, where the housing is built up of metal with a glass window plate, is used.
