Embodiment Construction

[0149] Hereinafter, it demonstrates referring drawings.

[0150] FIG. 1 shows an embodiment of a color cathode ray tube of the present invention. The color cathode ray tube 31 of the present embodiment includes a cathode ray tube body 35 composed of a panel 32 and a conical tube 34 having a neck 33, and phosphor layers of red, green and blue colors are formed on the inner surface of the panel 32. The color fluorescent surface 36 of the present invention is arranged opposite to the colored fluorescent surface 36 at the same time, and the electron gun 38 is arranged in the neck 33 . The color fluorescent surface 36 is formed by arranging, for example, stripe-shaped phosphor layers of each color. A deflection yoke 39 is arranged on the outer side of the tube body 35 .

[0151] In this cathode ray tube 31, three electron beams B [BR, BG, BB] corresponding to red (R), green (G) and blue (B) emitted from the electron gun 38 are selected by the color selection mechanism 37. The co...

Abstract

The present invention provides a color cathode-ray tube, a method for manufacturing thereof, a color selection mechanism, and a flame for the color selection mechanism, in order to improve the temperature drift of the beam landing. According to the present invention, the color selection mechanism having the flame formed of a pair of supporting members and a pair of elasticity providing members in which a color selection mask is provided with tension between the pair of supporting members is provided. Also, as the flame, such as a flame in which the pair of elasticity providing members is made of a flat plate and a surface of the plates is opposed to each other, a flame in which the pair of supporting members with approximately L-shaped cross section is inclined and disposed, or a flame in which both of the elasticity providing members and the supporting members are combined can be employed. The present invention provides the color cathode-ray tube including these color selection mechanism.

Description

technical field [0001] The present invention relates to a cathode ray tube suitable for use in color television receivers, computer monitors, and other display devices and its manufacturing method, a color selection mechanism suitable for such a cathode ray tube, and a frame for the color selection mechanism . Background technique [0002] Fig. 39 shows a schematic structure of a conventional color cathode ray tube. This color cathode ray tube 1 has a cathode ray tube body 5 composed of a face plate 2 and a conical tube 4 having a neck 3. On the inner surface of the face plate 2, color phosphors composed of phosphor layers of red, green, and blue colors are formed. Surface 6, and the color selection mechanism 7 is arranged opposite to the color fluorescent surface 6, and the electron gun 8 is arranged in the neck 3. The color fluorescent surface 6 is formed, for example, by arranging stripe-shaped phosphor layers of each color. A deflection yoke 9 is provided outside the ...
