  • Identification of image displays and their component parts
    Patent number: 5214350
    Abstract: An image display such as a cathode ray tube or flat panel display has an envelope with an external surface and an interior or otherwise non-external surface. Encapsulated indicia may be located on an external surface, or in the preferred embodiment, on an internal surface readable from the external surface. The indicia, being encapsulated on the interior surface, are safe from degradation, thus allowing for easy formation of the indicia by simple printing means which utilize fluid inks.
