Abstract
Perfeccionamientos introducidos en un tubo de imagen en color que tiene un cañón de electrones en línea para generar y dirigir tres haces de electrones, que comprenden un haz central y dos haces externos, a lo largo de trayectorias coplanarias hacia una pantalla de dicho tubo, pasando los haces a través de una zona de deflexión adaptada para tener campos de deflexión magnética vertical y horizontal establecidos en ella, y que tiene primeros medios para debilitar el efecto de partes de ambos campos de deflexión horizontal y vertical sobre los dos haces de electrones externos, caracterizados porque están previstos segundos medios para debilitar el efecto de una parte del campo de deflexión magnética horizontal sobre el haz de electrones central, y mantener un efecto no alterado del campo magnético vertical sobre el haz de electrones central.
