  • Patent number: 5936339
    Abstract: A color image receiving tube comprising three color (red, green and blue) phosphor screens on an inner surface of a face-plate; wherein at least two of said three color phosphor screens are coated with pigments; and wherein said three color phosphor screens have a total reflective brightness less than 70% that of three color phosphor screens with no pigment coating. According to the above-mentioned constitution, a color image receiving tube having a higher emisson brightness and contrast is achieved as compared to a color image receiving tube having the same reflective brightness, where the reflective brightness is obtained by lowering the light transmittance of its face-plate.
