Abstract

LA INVENCION EXPONE UN DISPOSITIVO DE PRESENTACION DE CRISTAL LIQUIDO DE MATRIZ ACTIVA BASADO EN UN CONTROL DE VOLTAJE (VOLTAJE DE MANDO NO CERO) DE LA BIRREFRINGENCIA (NEGATIVA O POSITIVA) DE LA CELULA DE CRISTAL LIQUIDO. EN EL DISPOSITIVO, UNA PLACA DE SUELO (TIERRA) COMPRENDE UNA PIEZA DE VIDRIO "E" CON UN REVESTIMIENTO CONDUCTOR TRANSPARENTE "F" TAL COMO OXIDO DE ESTAÑO IRIDIO. UN PIEZA EN FORMA DE BARQUILLO DE SILICIO "G" CON CIRCUITOS INTEGRADOS SOBRE EL, TIENE UN REVESTIMIENTO DE POLIMERO "H" PARA ALINEAR MOLECULAS DE CRISTAL LIQUIDO "I". EL VIDRIO REVESTIDO "E" TAMBIEN TIENE UN REVESTIMIENTO "J" PARA ALINEAR LAS MOLECULAS DE CCRISTAL LIQUIDO.
