Abstract
Un dispositivo de exhibición de imágenes que tiene un tubo de imagen para exhibir imágenes en color, que comprende en una envolvente en la que se ha hecho el vacío medios para generar uno o más haces de electrones, estando compuesta dicha envolvente de una ventana de imagen que tiene en el interior una pantalla de imagen, un cono y un cuello, estando dicho cono revestido en su interior con una capa conductora y estando dicho cono revestido parcialmente en su exterior con una capa de baja resistencia, estando provisto un sistema de bobinas de desviación alrededor de la parte de transición cuello-cono de la envolvente del tubo de imagen, caracterizado por el hecho de que al menos la región de la envolvente situada bajo el sistema de bobinas de desviación está revestida con una capa de resistencia muy alta que tiene una resistencia comprendida entre 10 6 y 10 10 ohmios por unidad de superficie, estando conectada eléctricamente dicha capa de alta resistencia a la capa de baja resistencia en elexterior del cono.
