METHOD OF MANUFACTURING A COLOR FILTER CATHODE RAY TUBE (CRT)

摘要

A color filter luminescent screen (22) assembly for a cathode ray tube (CRT) (10) is disclosed. The luminescent screen assembly is formed on an interior surface of a faceplate panel (12) of the CRT tube. The luminescent screen assembly includes a patterned light-absorbing matrix (23) that defines a plurality of sets of fields corresponding to one of a blue region, a red region and a green region. A color filter is formed in one of the plurality of sets of fields. The color filter may be, for example, a blue pigment layer, a red pigment layer or a green pigment layer. After the pigment layer is formed, a cap layer (66) is formed thereon. The cap layer is formed from an aqueous solution of a photosensitive material and a polymer. Thereafter, a phosphor layer is deposited on the cap layer.
