<p>An improved method of manufacturing a display screen for a cathode tube in which a coating of a material such as phosphor is provided on the back surface of the display screen and more particularly on the metallic backing of the display screen. This is accomplished by subjecting the metallic coated screen to a suitable vapor until the screen is saturated with vapor and then depositing the phosphor onto the back surface of the metallic backing layer by suitable screening techniques such as settling. The resulting structure is comprised of two phosphor layers with a metallic barrier sandwiched between the phosphor layers.</p> |
