Abstract: A composition and method of forming an internal neutral density filter on a luminescent screen assembly of a cathode ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a glass faceplate panel of the CRT tube. The luminescent screen assembly includes a patterned light-absorbing matrix that defines three sets of fields corresponding to one of a blue region, a green region and a red region. An internal neutral density filter is formed on the light-absorbing matrix. An array of blue, green and red color phosphors is formed on the internal neutral density filter corresponding to one of the blue region, the green region and the red region defined in the light-absorbing matrix. The internal neutral density filter has a composition including a red pigment, a blue pigment and at least one non-pigmented oxide particle.

Abstract: A cathode ray tube and a color selecting member, which can be manufactured without defects by using an existing projection aligner of a simple structure and can always produce a picture of high quality, and manufacture methods thereof. A phosphor layer has a pattern in stripes in the lateral direction of a screen, or in the horizontal direction. A color selecting member has slits elongated in the longitudinal direction of the screen, or in the horizontal scan line direction. Even in case of the thermal expansion of the color selecting member or a considerable longitudinal deviation between the exposure position at the time of manufacture and the position where an electron beam strikes in practical use, an electron beam can freely pass through the slits. Therefore, the accuracy of irradiation of the phosphor layer with the electron beam is not adversely influenced.

Abstract: The present invention relates to a tracking picture tube of the type in which comb-shaped electrodes or optical detecting means (22, 23) are used for generating a signal relative to the position of electron beams (9r, 9g, 9b) deflected onto phosphor strips (5r, 5g, 5b). The tube is characterized in that a first peripheral (uppermost) strip (5r) of said group of adjacent strips borders only finger portions (24a, 24b) of the first detecting means (22) in said pair of detecting means, and a second peripheral (lowermost) strip (5b) of said group of adjacent strips borders only finger portions (25a, 25b) of the second electrode (23) in said pair of detecting means. This configuration ensures improved tracking of the beams with respect to the centrally located phosphor strip.
