GASEOUS-DISCHARGE A C INDICATING PANEL Russian patent published in 1998 - IPC

FIELD: electrical engineering, systems displaying videoinformation on gaseous-discharge AC indicating panels. SUBSTANCE: increased luminous efficiency in filed variants of family of single- object inventions is achieved thanks to creation of gap between vertexes of barriers and clear dielectric of first plate thanks to formation of additional dielectric protrusions on barriers or thanks to formation of additional barriers on surface of clear dielectric between groups of indication electrodes or thanks to increased height of individual barriers contacting clear dielectric of first plate. EFFECT: increased luminous efficiency of panel, reduced operating voltage of flat panel screen. 5 cl, 3 dwg
