Abstract

PURPOSE: To decrease the color temperature change on the first fluorescent screen as well as to increase the life time of the color Braun tube, by removing the mask plate at the area which corresponds to the first fluorescent screen of the reference white color of the shadow mask and then providing an aperture at the area to modulate the beam current density which excites the first fluorescent screen.
