Abstract

UNA CELDA DE PANTALLA DE CRISTAL LIQUIDO COMPRENDE DOS PAREDES DE CELDA SEPARADAS ENTRE SI PARA ENCERRAR UNA CAPA DE MATERIAL DE CRISTAL LIQUIDO. LAS PAREDES DE LA CELDA SOPORTAN ESTRUCTURAS DE ELECTRODO, POR EJEMPLO DISPUESTAS EN FILAS Y EN COLUMNAS PARA OBTENER UNA MATRIZ X,Y DE ELEMENTOS DIRECCIONABLES O PIXELES. EL MATERIAL DE CRISTAL LIQUIDO SE ALINEA MEDIANTE UNA ESTRUCTURA DE RETICULA (ACANALADA) EN UNA O EN AMBAS PAREDES DE LA CELDA. ESTA ESTRUCTURA DE RETICULA ES UNA BIRRETICULA CON UNA RETICULA SIMETRICA Y UNA RETICULA ASIMETRICA QUE PUEDE SER ORTOGONAL CON RESPECTO A LA RETICULA SIMETRICA. LAS ACANALADURAS DE LA RETICULA SIMETRICA VARIAN EN SU PROFUNDIDAD O ASIMETRIA A LO LARGO DE SUS LONGITUDES PARA DAR UNA PREINCLINACION LOCALMENTE VARIABLE CUYO ALCANCE MEDIO MAS GRANDE SUMINISTRA UNA PREINCLINACION EN UNA BANDA PREFERIDA, POR EJEMPLO ALREDEDOR DE 2 (GRADOS) -24 (GRADOS) .
