Abstract (en)

[origin: US4242372A] Luminescent materials are adhered to TV color picture screens or image display device screens by coating the inner surface of a glass screen substrate with a conductive or non-conductive C1 to C4 alcoholic or carboxylic solution containing oxygen-rich organic materials selected from the group consisting of silicon salts of relative low molecular weight carboxylic acids, tin salts of relatively low molecular weight carboxylic acids (which can be optionally doped to render them conductive, if desired) or mixtures thereof or a doped tin compound, at least partially drying such coating, as at a temperature of about 150 DEG C., applying a select pattern of luminescent materials onto such partially dried coating and curing or tempering the resultant structure, as at a temperature of about 500 DEG C. so that the luminescent material is firmly embedded within the conductive/non-conductive coating.

Abstract (de)

Für ein Verfahren zum Herstellen gut haftender Leuchtstoffschichten (3) für Farb-Bildschirme und Farb-Bildanzeigegeräte wird erfindungsgemäß vorgeschlagen, die innere Oberfläche des Schirmglases (1) mit einer Siliciumdioxidschicht und/oder dotierten Zinnoxidschicht zu versehen, wobei als Ausgangsmaterialien alkoholische Lösungen von sauerstoffreichen organischen Silicium- und/oder Zinnverbindungen verwendet werden, und zwischen dem Trocknen und Tempern dieser Schicht (2) die Leuchtstoffschichten (3) aufzubringen.
