Abstract

UNA PANTALLA DE CRISTAL LIQUIDO FERROELECTRICO QUE MUESTRA CARACTERISTICA DE ALIENACION UNIFORME MEJORADA Y CARACTERISTICA DE CONMUTACION ESTA CONSTITUIDA POR UN PAR DE UN SUSTRATO SUPERIOR Y UN SUSTRATO INFERIOR, UN CRISTAL LIQUIDO ESMECTICO QUIRAL DISPUESTO ENTRE LOS SUSTRATOS INFERIOR Y SUPERIOR. CADA UNO DE LOS SUSTRATOS INFERIOR Y SUPERIOR POSEE UN ELECTRODO PARA APLICAR UN VOLTAJE AL CRISTAL LIQUIDO Y UNA PELICULA DE ALINEACION UNIAXIAL. LAS PELICULAS DE ALINEACION EN LOS SUSTRATOS INFERIOR Y SUPERIOR DISPONEN DE EJES DE ALINEACION UNAXIAL QUE SE CRUZAN ENTRE SI DE MODO QUE LA DIRECCION DE CRUCE DE LOS EJES DE ALINEACION UNIAXIAL DEL SUSTRATO INFERIOR HASTA EL SUSTRATO SUPERIOR ES IDENTICA A LA DIRECCION DE TORSION HELICOIDAL EN FASE COLESTERICA DEL CRISTAL LIQUIDO ESMECTICO QUIRAL, Y EL CRISTAL LIQUIDO ESMECTICO QUIRAL ESTA DISPUESTO EN TAL ESTADO DE ALINEACION QUE EL CRISTAL LIQUIDO MUESTRA UN ANGULO DE PREINCLINACION (ALFA), UN ANGULO DE CONO, UN ANGULO DE INCLINACION (DELTA) DE CAPA SMC*, UN ANGULO DE INCLINACION APARENTE A QUE SATISFACE LAS RELACIONES DE: Y . LA DIRECCION DE CRUCE PUEDE TENER PREFERENTEMENTE UNA POLARIDAD (TOMADA COMO "POSITIVA" EN SENTIDO HORARIO Y COMO "NEGATIVA" EN SENTIDO ANTIHORARIO) QUE EQUIVALE A LA POLARIDAD DE LA POLARIZACION ESPONTANEA DEL CRISTAL LIQUIDO.
