Color image receiving tube |
摘要 |
A color image receiving tube comprising three color (red,green and blue) phosphor screens (6R, 6G, 6B) on an inner surface of a face-plate 4; wherein at least two of said three color phosphor screens are coated with pigments(7R, 7G, 7B); 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. <IMAGE> |
