Abstract
SE DESCRIBE UN DISPLAY DE CRISTAL LIQUIDO QUE INCLUYE CAPACIDAD EN LA ESCALA DE GRISES. CADA PIXEL DEL DISPLAY ESTA SUBDIVIDIDO EN VARIOS SUBPIXELES (SO-SQ). CADA SUBPIXEL INCLUYE UN HABILITADOR EFECTIVO (C(LC)-O-C(LC)Q), CON EL MATERIAL DE CRISTAL LIQUIDO CONTENIDO ENTRE LAS PLACAS DEL HABILITADOR EFECTIVO, E INCLUYE UN HABILITADOR DE CONTROL (CO-CQ) ACOPLADO EN SERIE CON EL HABILITADOR EFECTIVO. CONTROLANDO LA CAPACITANCIA DE LOS HABILITADORES DE CONTROL DE LOS SUBPIXELES, EN SUBPIXELES SELECCIONADOS PUEDEN SER ACTIVADOS COMO UNA FUNCION DEL VOLTAJE (VA) APLICADO A TRAVES DEL HABILITADOR. CONTROLANDO EL NUMERO DE SUBPIXELES QUE ESTAN ACTIVADOS POR EL VOLTAJE APLICADO, LA CAPACIDAD EN LA ESCALA DE GRISES PUEDE SER PROPORCIONADA POR EL DISPLAY DE CRISTAL LIQUIDO.
