Abstract
In a dynamic focus electron gun, a horizontal dynamic focus voltage is varied according to those portions of a screen where the electron beam arrives and is applied so that the peak-to-peak amplitude of the horizontal dynamic focus voltage in one horizontal deflection period for the upper and lower portions of the screen is greater than that for the screen's center, thereby accomplishing uniform beam spots throughout the screen.
