Apparatus for fabricating a color cathode ray tube |
摘要 |
The invention provides conjunctive apparatus for facilitating the fabrication of the basic pattern windowed-web portion of a color cathode ray tube screen structure formed in the viewing area of the face panel. In accordance with the invention, additional photo-exposure of the panel is discretely effected by the apparatus to polymerize a defined band of coating confined to the sidewall portion of the panel. The presence of this band subsequently facilitates expeditious removal of extraneous graphite coating from the panel sidewall, from the mask positioning studs embedded therein, and from the terminal sealing edge therearound. Thus, the apparatus of the invention provides desirably bare sidewall-associated surfaces that are free of deleterious particulate matter.
