Abstract

Un dispositivo perfeccionado de presentación de imágenes en colores, que comprende un tubo de imagen para color que tiene al menos un ánodo final y un electrodo de rejilla de pantalla, un generador de alta tensión para generar una alta tensión para el ánodo final y un generador de desviación de línea para generar una corriente de desviación de línea a través de una bobina de desviación de línea y que comprende un rectificador para rectificar impulsos de retorno de línea con el fin de generar una tensión de alimentación para el electrodo de rejilla de pantalla, estando separados dichos generadores uno de otro, que comprende además un generador de desviación de campo para generar una corriente de desviación de campo a través de una bobina de desviación de campo y un generador de corrección de retícula este-oeste para la modulación parabólica a la frecuencia de campo de la amplitud de la corriente de desviación de línea.
