FIELD: electric engineering, possible use for manufacturing and lighting electromagnetic display panels.
SUBSTANCE: method includes using ultraviolet fluorescent dyes in paints or plastic material for reflective surface of selected pixel element, in place of common reflecting dye. Aforementioned dyes absorb invisible light of short-range ultraviolet spectrum and, after absorption, reemit it in visible spectrum.
EFFECT: decreased contrast of display panel under bad lighting conditions, improved angular visibility and contrast of display.
