ABSTRACT:
The invention relates to an improved planar electrode member for use in an in-line multi-beam cathode ray tube electron gun assembly. The improved electrode is a substantially planar one-piece member having a plurality of apertures therein. The side portions of the member have longitudinal strengthening bends formed therealong in conjunction with a plurality of rib embossments spatially formed as traversals crossing the member to join the side oriented bends thereby providing improved strengthening to the structure.
