Abstract

Se describe un proyector de pantalla de cristal líquido ferroeléctrico, que emplea una pantalla fluorescente, que incluye una fuente de luz que emite luz de una longitud de onda predeterminada; una primera lente de condensacion para convertir la luz radiada de la fuente de luz a haces de luz; un separador de haz de luz de polarizacion para seleccionar una luz direccional predeterminada en la luz incidente que pasa a través de la primera lente de condensacion y para polarizar la luz; un obturador de encendido/apagado de cristal líquido ferroeléctrico operado de acuerdo con la operacion de polarizacion del separador de haz de luz de polarizacion, el obturador de cristal líquido ferroeléctrico comprende una capa de reflexion unida a la parte trasera y dispositivos RAM unidos sobre cada pixel de una pantalla de cristal líquido ferroeléctrico (FLC); un sistema optico para agrandar, a una relacion predeterminada, la luz reflejada del obturador de cristal líquido ferroeléctrico; y una pantalla fluorescente de un material fluorescente, el cual irradia a través de luz, pasando a través del sistema optico, a una longitud de onda predeterminada.
