Abstract

Esta invención se refiere a un dispositivo de indicación visual o pantalla, de cristal líquido, compatible con gafas protectoras para visión nocturna, totalmente coloreadas, que logra una iluminación uniforme y una integridad de color a ángulos amplios de visión, creando una luz uniforme, alineada, en un montaje de iluminación de fondo, antes de que la luz alcance un filtro de IR próxima que tiene un corte agudo entre la región próxima de rayos IR y el rojo, y después de esto difunde la luz que es emitida desde el filtro, para crear el ángulo amplio de la visión.
