ALTERNATING CURRENT GAS-DISCHARGE INDICATION BOARD Russian patent published in 1997 - IPC

FIELD: microelectronics. SUBSTANCE: device has first dielectric plate, which has pairs of opposite-polarity indication electrodes which are covered with dielectric material. Said electrodes have lower wide part which is made from transparent material and upper narrow part which is made from opaque material, is located above lower one and has control electrodes which intersect to indication electrodes so that gas-discharge cells are provided. In addition device has separating members which embrace cells. Depth of dielectric cover over opaque electrode parts (d₁) and over transparent electrode parts (d₂) conform to condition: . EFFECT: increased functional capabilities. 4 cl, 5 dwg
