Abstract
A gas discharge display screen with a self-scanning function is described herein. All the electrodes are positioned coplanary on a single surface of a rear insulating plate. First and second pluralities of parallel electrodes connected respectively independently accomplish respectively the scanning and displaying functions. A third plurality of parallel electrodes perpendicular to the first and second pluralities of electrodes cooperates with a particular electrode for preionizing the first gas cells of the matrix screen lines.
