Abstract

Un dispositivo de visualización de imagen que comprende un tubo de visualización de imagen, un circuito de deflexión de campo para generar una corriente de deflexión que tiene un periodo de explotación y un periodo de retroceso a través de una bobina de deflexión de campo para la desviación vertical de uno o más haces de electrones generados en el tubo de imagen, y un generador de impulsos para generar una señal para suprimir el haz o haces de electrones al menos en el periodo de retroceso de campo, caracterizado porque el generador de impulsos comprende un circuito puerta que tiene una función lógica "O" y que tiene medios para recibir dos señales de entrada, a saber una primera señal derivada del circuito de deflexión de campo y una segunda señal derivada de la bobina de deflexión de campo, produciendo el circuito puerta la señal de supresión para el haz o haces de electrones.
