Abstract
Perfeccionamientos introducidos en un tubo de presentación de imágenes en color que comprende, en un medio de envoltura en que se ha hecho el vacío para generar cierto número de haces de electrones, una pantalla de presentación de imágenes que comprende un gran número de regiones que son luminiscentes en colores diferentes, y medios de selección de color provistos de un gran número de aberturas que asocian cada haz de electrones a regiones luminiscentes de un color, cuyos medio de selección de color comprende un primer y un segundo sistemas de electrodos de lentes, perteneciendo un electrodo de lentes al primer sistema estando conectado a un electrodo de lentes que pertenece al segundo sistema por medio de un miembro aislante, caracterizado porque dicho miembro aislante está constituido por una hoja de un material eléctricamente aislante que está perforado por lo menos en la zona de dichas aberturas.
