Abstract

"ARQUITETURA DE MáQUINA DE LUZ MAIS LUMINOSA PARA UM SISTEMA DE PROJEçãO DE DISPLAY DE CRISTAL LìQUIDO". Um sistema de projeção de display de cristal liquido, compreendendo: uma fonte de uma seq³ência de três cores repetitiva de luz (13); primeiro e segundo formadores de imagem (20, 22) responsivos ao mesmo sinal de excitação; pelo menos um primeiro divisor de feixe de polarização (14) para separar a dita seq³ência de três cores repetitiva de luz em uma seq³ência polarizada P de três cores de luz e uma seq³ência polarizada S de três cores de luz, a dita seq³ência polarizada S de três cores de luz iluminando o dito primeiro formador de imagem e a dita seq³ência polarizada P de três cores de luz iluminando o dito segundo formador de imagem; um primeiro filtro (26) para remover a luz polarizada P direcionada para o dito primeiro formador de imagem; um segundo filtro (24) para remover luz a polarizada P refletida do dito segundo formador de imagem, e o dito pelo menos primeiro divisor de feixe de polarização combinando a dita luz refletida do dito primeiro formador de imagem e a dita luz filtrada através do dito segundo filtro como uma saída.
