Abstract
UN DISPLAY DE CRISTAL LIQUIDO ES DESCRITO, QUE INCLUYE LA IDONEIDAD EN LA ESCALA DE GRISES. CADA PIXEL DEL DISPLAY ESTA SUBDIVIDIDO EN VARIOS SUBPIXELES. CADA SUBPIXEL TIENE ACOPLADO UN DELGADO TRANSISTOR DE PELICULA, EL DELGADO TRANSISTOR DE PELICULA ACOPLADO AL VERDADERO CAPACITADOR DEL SUBPIXEL. EL MATERIAL DEL CRISTAL LIQUIDO ESTA CONTENIDO ENTRE LAS PLACAS DEL CAPACITADOR VERDADERO. EL VOLTAJE APLICADO AL CAPACITADOR VERDADERO RESULTANTE DEL FLUJO DE CORRIENTE A TRAVES DEL DELGADO TRANSISTOR DE PELICULA CONTROLE LA CAPACIDAD OPTICA DEL SUBPIXEL. CONTROLANDO LOS PARAMETROS ASOCIADOS CON EL DELGADO TRANSISTOR Y CONTROLANDO EL VOLTAJE APLICADO AL PIXEL (Y A LOS TRANSISTORES DELGADOS DE PELICULA DE LOS SUBPIXELES), LAS PROPIEDADES OPTICAS DEL SUBPIXEL PUEDEN SER CONTROLADOS PARA PROPORCIONAR UNA ESCALA DE GRISES ANGULAR INDEPENDIENTE PARA EL PIXEL.
