Abstract

PURPOSE:To eliminate spherical aberration and to improve converjence characteristic of focus electron lens by positioning multiple electron gun electrode structure used for color CRT so that the incidence angle of electron beam to the main electron lens is made to be small to produce a single uniform beam.
