Abstract
A one-piece grid assembly for use in an electron gun for a miniature cathode-ray tube application that consists of a core made of an electrically insulating material, a first grid deposited on the core, and a second grid deposited on the core that is spaced apart from the first grid, and a method of making the one-piece grid assembly by first compression molding the core and then depositing the grid by plating are disclosed.
