Abstract

DISPOSITIVO DE VISUALIZACION (1) QUE CONSTA DE UNA MATRIZ (2) DE CELDAS DE CRISTAL LIQUIDO (3) POSICIONABLES DE FORMA SELECTIVA Y VARIAS FUENTES LUMINOSAS (4,5,6) QUE PRODUCEN UNA PLURALIDAD DE HACES LUMINOSOS DE DIFERENTES COLORES. UNOS OBTURADORES DE LUZ (7,8,9 O 20) SITUADOS ENTRE LA MATRIZ (2) Y LAS FUENTES LUMINOSAS (4,5,6) INCLUYEN VARIAS PARTES DE CRISTAL LIQUIDO (7,8,9 O 21) CONMUTABLES CADA UNA ENTRE UN MODO DE TRANSMISION DE LUZ Y UN MODO DE BLOQUEO DE LA MISMA. LA ILUMINACION SECUENCIAL CON SELECCION DEL COLOR DE LA MATRIZ SE EFECTUA POR LA CONMUTACION APROPIADA DE LAS PORCIONES DE CRISTAL LIQUIDO (7,8,9 O 21) ENTRE LOS MODOS.
