Abstract

LA INVENCION DEL CRISTAL LIQUIDO FERROELECTRICO SE BASA EN DISPONER UN CRISTAL LIQUIDO FERROELECTRICO ENTRE UN PAR DE SUBSTRATOS, TENIENDO ADEMAS CADA UNO UN GRUPO DE ELECTRODOS PARA IMPULSAR AL CRISTAL LIQUIDO FERROELECTRICO Y PROVISTOS CON UN EJE ALINEADO UNIAXIAL PARA ALINEAR LAS MOLECULAS DEL CRISTAL LIQUIDO FERROELECTRICO. LOS EJES UNIAXIALES ALINEADOS PROVISTOS AL PAR DE SUBSTRATOS ESTAN DISPUESTOS PARA ENTRECRUZARSE UNO CON OTRO EN UN ANGULO DE INTERSECCION PREESTABLECIDO, Y LAS MOLECULAS DEL CRISTAL LIQUIDO ESTAN ALINEADAS PARA DAR AL CONTROL DE FORMACION UN ANGULO DE PRE-INCLINACION DE 5 A 35 UPERFICIES DE ALINEAMIENTO DEL CRISTAL LIQUIDO DE LOS SUBSTRATOS. LA INVENCION DEL CRISTAL LIQUIDO FERROELECTRICO DA UN CONTRASTE MEJORADO TANTO COMO UN GRAN MARGEN DE CONDUCCION.
