Applicable for alternating current
(AC) electric field energy conversion into visible light. For example:
night, emergency and masking lighting, photographic printing, brightening
of liquid-crystal displays and dials in control panels of cars and
planes, control desks of various designation, measuring instrument,
scales, radio- and television sets, phone dials etc. Representation
of symbol and graphic information in machine building, instrument
making, aviation and cosmic branches etc. as well as for flat television
screens.
Its advantages are immediate electrical energy
conversion into light, applicability in flat solid and flexible designs
of light sources and devices for information representation, reliability
and vibrostability of said devices, quick action, wide angle of survey
and broad range of operating temperatures for electroluminescent devices |
