Process for disposing an opaque conductive band on the sidewall of a CRT panel

摘要

The invention provides a multi-step photo-process for disposing a definitive band of opaque conductive material on the sidewall portion of a CRT face panel. The process provides coating the panel with a photosensitive material and discretely exposing the viewing area and terminal region of the sidewall to polymerize the material thereon. The intermediate unexposed coating is removed, and at least the sidewall portion, coated with an opaque conductive material. The polymerized coatings are degraded and removed, leaving a precisely defined band of opaque conductive material on the panel sidewall, and making electrical contact with the aperture mask supporting studs embedded therein.
