GASEOUS-DISCHARGE A C INDICATION PANEL Russian patent published in 2002 - IPC

FIELD: electronics, facilities displaying sign-graphical and TV information. SUBSTANCE: high reliability of control over gaseous-discharge A C indication panel is provided thanks to manufacture of spacers fixing distance between dielectric plates of gaseous-discharge A C indication panel from refractory material which coefficient of linear thermal expansion K_sp amounts to ( 0.85-1.25 ) of coefficient of linear thermal expansion of dielectric covering electrodes. In this case spacers are placed at distance of 15-40 mm one from another. Maximum linear dimension l ( mm ) in direction of electrodes is chosen from relationship 0,1mm≤l≤0,9•l₁, where l₁ - is distance between neighboring edges of adjacent electrodes, mm. EFFECT: high reliability of control over gaseous- discharge A C indication panel thanks to provision for large range of memory. 1 dwg
