Abstract

EL APARATO DE DISPOSITIVO DE CRISTAL LIQUIDO ESTA COMPUESTO POR, EL USO (A) DE UN PANEL DE CRISTAL LIQUIDO QUE COMPRENDE UN PAR DE SUBSTRATOS, CADA UNO PROVISTO DE UN ELECTRODO Y UN CRISTAL LIQUIDO COLOCADO ENTRE LOS SUBSTRATOS EN COMBINACION CON (B) UN MIEMBRO DE SUJECCION QUE TIENE UNA ESTRUCTURA PARA SUJETAR EL PANEL DE CRISTAL LIQUIDO. EL PANEL DE CRISTAL LIQUIDO ESTA FIJADO AL ARMAZON DEL MIEMBRO DE SUJECCION DE MANERA FLOTANTE, POR MEDIO (C) DE UN MIEMBRO ELASTICO, DE TAL MANERA QUE DEFINE UN ESPACIO CASI CERRADO, DETERMINADO POR EL PANEL DE CRISTAL LIQUIDO, EL MIEMBRO DE SUJECCION Y EL ELASTICO. EL ESPACIO CASI CERRADO FUNCIONA PARA SUPRIMIR UNA DEFORMACION EN FLEXION, CUANDO ES USADA EN COMBINACION CON UN CALENTADOR PLANAR PARA CALENTAR EL PANEL DE CRISTAL LIQUIDO.
