Abstract

PIXELES DE CRISTAL LIQUIDO. INCLUYE: DIFERENTES CELULAS (12) DISPUESTAS SOBRE UNA OBLEA (11) DE SILICIO CON ELEMENTOS DIRECCIONADORES DE LOS PIXELES; COMPRENDIENDO CADA CELULA UN ELECTRODO POSTERIOR (13) METALICO Y UN ELECTRODO (14) FRONTAL TRANSPARENTE, POR MEDIO DE LOS CUALES UN CRISTAL DE P-HEXILIXI BENCILIDONE-P-AMINO-2-CLORO-PROPIL CINAMATO FERRO-ELECTRICO (16) SITUADO ENTRE ELLOS PUEDE SER CONMUTADO ENTRE SUS DOS ESTADOS ESTABLES, Y UN UNICO POLARIZADOR (17) A TRAVES DEL CUAL SE VISIONA EL DISPLAY POR REFLEXION ESPECULAR DE LA LUZ Y UN TAMIZ DICRONICO. SIENDO: EL ESPESOR OPTICO DE CADA CELULA UN NUMERO IMPAR DE CUARTOS DE LONGITUDES DE ONDA DIVIDIDO POR LA BIRREFRINGENCIA DEL MATERIAL DE CRISTAL. SE UTILIZA, COMO COMPONENTE ELECTRONICO, EN APARATOS DE CONTROL.
