Abstract

PURPOSE: To simplify the structure of the electrode without imparring the roundness of the spot for the CRT electronic gun, by forming both the intermediate grid electrode and the fluorescent screen side grid electrode with use of the cup electrode and forming the cylinder part's height lower than nearly a perfect cylinder in terms of electronics.
