Abstract
LA INVENCION SE REFIERE A UNA PANTALLA DE CRISTAL LIQUIDO QUE COMPRENDE UNA CELDILLA DE VISUALIZACION QUE CONTIENE MATERIAL CRISTALINO LIQUIDO Y UNA CAPA DE RETARDO, COMPRENDIENDO DICHA CAPA DE RETARDO UN SUSTRATO Y UNA CAPA DE MATERIAL DE ALTO PESO MOLECULAR, PREFERIBLEMENTE LIGERAMENTE ENTRECRUZADO, DONDE EL MATERIAL DE ALTO PESO MOLECULAR TIENE UNA FASE NEMATICA POR ENCIMA DE SU TG Y UNA VISCOSIDAD DINAMICA A LA TEMPERATURA DE TRABAJO DE AL MENOS 100 PA.S, Y LA DIFERENCIA ENTRE LA TC DEL MATERIAL DE ALTO PESO MOLECULAR Y LA TC DEL MATERIAL DE BAJO PESO MOLECULAR DE LA CELDILLA DE VISUALIZACION (TC CELL ) ES DEL ORDEN DE -30 (GRADOS) C A +30 (GRADOS) C, PREFERIBLEMENTE DEL ORDEN DE -20 (GRADOS) C A +20 (GRADOS) C, Y MAS PREFERIBLEMENTE DEL ORDEN DE -10 (GRADOS) C A +10 (GRADOS) C; Y LA TG DEL MATERIAL CRISTALINO LIQUIDO DE ALTO PESO MOLECULAR ES INFERIOR A 50 (GRADOS) C. SE HA DESCUBIERTO QUE SI SE UTILIZA MATERIAL DE ALTO PESO MOLECULAR CON UNA TC COMPARABLE A LA DEL MATERIAL CRISTALINOLIQUIDO, PREFERIBLEMENTE DE BAJO PESO MOLECULAR, DE LA CELDILLA ACTIVA, LA TERMODEPENDENCIA DEL VALOR DE RETARDO DE LA CAPA DE RETARDO ES COMPARABLE A LA DE LA CELDILLA ACTIVA DENTRO DE LA GAMA DE TEMPERATURAS EN LA QUE SE UTILIZAN LAS PANTALLAS. SE HA DESCUBIERTO ADEMAS QUE MEDIANTE EL ENTRECRUZAMIENTO DEL MATERIAL CRISTALINO LIQUIDO DE ALTO PESO MOLECULAR, LAS CAPAS DE RETARDO DE LA INVENCION SE VUELVEN MENOS SUSCEPTIBLES A LA FORMACION DE POROSIDADES Y A LA VARIACION INDESEADA DE LA TORSION, Y TIENEN MEJOR ESTABILIDAD MECANICA.
