Abstract

Un tubo de imagen de color para visualizar imágenes en color, que comprende en una ampolla con vacío interior medios para general un número de haces de electrones, una pantalla de imagen que comprende un gran número de regiones que emiten luz por luminiscencia en colores diferentes, y medios de selección de color que comprenden un gran número de aberturas que asignan cada haz de electrones a regiones luminiscentes de un color individual, estando formados los mencionados medios de selección de color por una rejilla consistente en dos conjuntos de conductores paralelos que se cruzan, estando aislados entre sí dichos conductores en los puntos de cruce y estando interconectados los conductores de cada conjunto, caracterizado porque el primer conjunto de conductores consiste en hilos conductores y el segundo conjunto de conductores consiste en bandas metálicas fijadas por pares entre sí y que abrazan a los hilos conductores en los puntos de cruce, estando rodeados dichos hilos conductores coaxialmente en la zona de los puntos de cruce por medio de una capa de material de aislamiento.
