Abstract

TUBO DE RAYOS CATODICOS PARA PRESENTAR IMAGENES EN COLOR EN UNA PANTALLA QUE COMPRENDE UN GRAN NUMERO DE AREAS QUE PRODUCEN LUMINISCENCIA EN COLORES DIFERENTE. EL TUBO CONTIENE UNAS PLACAS ELECTROMAGNETICAS (2) QUE GENERAN UNA RADIACION ELECTRONICA (3, 4), LA CUAL A TRAVES DE UNAS ABERTURAS DE SELECCION DE COLOR (7) INCIDE SOBRE LA PANTALLA DE PRESENTACION (6). LOS MEDIOS DE SELECCION (7) ESTAN CONSTITUIDOS POR UNA PLACA FERROMAGNETICA CON ABERTURAS, EN CADA UNA DE LAS CUALES SE FORMA UNA LENTE ELECTRONICA. LA PANTALLA (6) TIENE UN GRAN NUMERO DE TIRAS DE FOSFORO QUE PRODUCEN LUMINISCENCIA EN ROJO, VERDE Y AZUL.
