Abstract

METODO PARA DIRECCIONAR UNA CELDA DE CRISTAL LIQUIDO DE MATRIZ CON UNA CAPA DE CRISTAL LIQUIDO FERROELECTRICA, TENIENDO VARIOS PIXELS DEFINIDOS POR AREAS DE SOLAPAMIENTO ENTRE LOS ELEMENTOS DE UN PRIMER CONJUNTO DE ELECTRODOS A UN LADO DE LA CAPA DE CRISTAL LIQUIDO Y LOS ELEMENTOS DEL SEGUNDO CONJUNTO DE ELECTRODOS AL OTRO LADO DE DICHA CAPA. CADA UNO DE LOS PIXELS TIENE UN PRIMER Y UN SEGUNDO ESTADOS DISTINGUIBLES OPTICAMENTE Y UN TIEMPO DE RESPUESTA PARA CONMUTAR ENTRE LOS DOS ESTADOS, QUE DEPENDE DE LA DIFERENCIA DE POTENCIAL EN LA CAPA DE CRISTAL LIQUIDO. EL METODO INCLUYE LA FASE DE APLICACION DE UNA ONDA A UN PIXEL SELECCIONADO PARA CONMUTARLO ENTRE LOS DOS ESTADOS. LA ONDA DE CONMUTACION VA EQUILIBRADA POR CARGA Y CONSTA DE UN PRIMER IMPULSO DE SUFICIENTE LONGITUD Y ALTURA PARA CONMUTAR EL PIXEL SELECCIONADO, Y UN SEGUNDO IMPULSO QUE CONTRIBUYE AL EQUILIBRADO POR CARGA. EL SEGUNDO IMPULSO TIENE UNA ALTURA MAYOR QUE LA SUFICIENTE CORRESPONDIENTE AL PRIMER IMPULSO, Y UNA LONGITUD INSUFICIENTE PARA CONMUTAR EL PIXEL SELECCIONADO.
