Abstract

ESTA INVENCION PROPORCIONA UNA PANTALLA DE CRISTAL LIQUIDO DE COLORES PLENOS (10) QUE TIENE UNA EFICIENCIA MEJORADA Y UTILIZA UN FILTRO DE COLOR HOLOGRAFICO SIN EJE (11). LA PANTALLA DE CRISTAL LIQUIDO COMPRENDE UN MODULADOR DE LUZ ESPACIAL DE CRISTAL LIQUIDO (12) QUE INCLUYE UN MOSAICO DE ELEMENTOS DE IMAGENES INDEPENDIENTES ELECTRICAMENTE. SE PROPORCIONA UNA FUENTE DE ILUMINACION (21) QUE PRODUCE UNA LUZ DE ILUMINACION PREDOMINANTEMENTE POLARIZADA S CON UN BLANCO CASI COLIMADO. EL FILTRO DE COLOR HOLOGRAFICO (11) ESTA COLOCADO ADYACENTE AL MODULADOR DE LUZ ESPACIAL DE CRISTAL LIQUIDO (12) QUE COMPRENDE TRES CAPAS DE LENTES HOLOGRAFICAS SUPERPUESTAS DISEÑADAS PARA ENFOCAR LUZ ROJA, VERDE Y AZUL, RESPECTIVAMENTE, EN LOS ELEMENTOS DE IMAGENES CORRESPONDIENTES DEL MODULADOR DE LUZ ESPACIAL (12). UN ELEMENTO DE PRISMA (22) ESTA COLOCADO ADYACENTE AL FILTRO DE COLOR HOLOGRAFICO (11) PARA ACOPLAR LA LUZ DE ILUMINACION PROCEDENTE DE LA FUENTE DE ILUMINACION (21) EN EL FILTRO DE COLOR HOLOGRAFICO(11). SE COLOCA UN POLARIZADOR (24) EN UNA SUPERFICIE DE SALIDA DEL ELEMENTO DE PRISMA (22) OPUESTA AL FILTRO DE COLOR HOLOGRAFICO (11) QUE TRANSMITE LUZ POLARIZADA P PERO BLOQUEA LA LUZ POLARIZADA S. UN SISTEMA OPTICO DE PROYECCION (30) ESTA DISPUESTO PARA RECIBIR LA LUZ POLARIZADA P TRANSMITIDA POR EL POLARIZADOR (24) Y PRODUCIR UNA IMAGEN PARA SU VISUALIZACION.
