Patent

CA 2175058

A method and apparatus (11) for coating a CRT screen (41) after assembly. The method and apparatus (11) includes isolating a surface portion of the CRT (42) to be coated from the remaining surface to prevent or minimize coating problems resulting from outgassing or difficulty in controlling coating process parameters and to isolate noncompatible components from the deposition environment.

L'invention concerne un procédé et un appareil (11) pour déposer des couches minces sur un écran cathodique (41) après assemblage. Le procédé et l'appareil (11) consistent à isoler de la surface restante une partie de la surface de l'écran cathodique (42) à revêtir. Cela permet de supprimer ou de minimiser les problèmes de revêtement dus au dégazage, ou de réduire les problèmes de contrôle des paramètres du processus de dépôt. Cela permet également d'isoler les composants non compatibles de l'environnement de dépôt.
