Электролюминесцентный индикатор С63.396.207
S63.396.207 Multi-segment Electroluminescent Display
Indicateur électroluminescent multi-segments
Elektrolumineszenz-Segmentanzeige

Green color. Eight independent segments.

Made only for military use in 80's Soviet era.
High brightness and durability.

This display is fundamentally different from VFDs in that it is not a vacuum tube, and does not have a hot cathode filament. Instead, an organic resin with a crystalline phosphor suspension is sandwiched between a conductive bottom layer and a tin oxide glass window to form a capacitor. When rapidly charged and discharged by a high voltage source (220 V AC 400-1000 Hz), the phosphor emits light. The indicator works also with 50 Hz, but not in full bright mode.
