Abstract

La presente invención se refiere a un sistema de exhibición en color que incluye un cinescopio que tiene un cañón electrónico para generar y dirigir tres haces electrónicos a lo largo de trayectorias hacia una pantalla del cinescopio; incluyendo el cañón electrodos que comprende una región formadora de haz y electrodos para formar una lente enfocadora principal; e incluyendo el sistema un yugo autoconvergente que produce un campo de deflexión magnética astigmático; caracterizado porque el sistema incluye: electrodos en el cañón electrónico para formar una lente multipolar entre la región formadora de haz y la lente enfocadora principal, en cada una de las trayectorias de haz electrónico; estando orientada cada lente multipolar para proveer una corrección a un haz electrónico asociado para compensar, al menos parcialmente, el efecto del campo de deflexión magnética astigmático sobre el haz asociado, en donde los electrodos para formar una lente multipolar incluyen dos electrodos, un primer electrodo de lente multipolar y un segundo electrodo de lente multipolar; estando conectado el segundo electrodo de lente multipolar a uno de los electrodos para formar una lente enfocadora principal, y estando situado el primer electrodo de lente multipolar entre el segundo electrodo de lente multipolar y la región formadora de haz, y enfrentando al primer electrodo de lente multipolar.
