Abstract: The present invention has an object to provide a method of manufacturing an electronic tube capable of eliminating deterioration of image quality due to an excessively high electron reflection effect of a material comprising a metal element with an atomic number not lower than 70 and painted on a shadow mask and deterioration of image quality due to spontaneous peeling of a coat on the surface of the shadow mask. A paint mainly comprising a solated metal oxide or a metal alkoxide of an element with an atomic number not lower than 40 is painted to form an electron reflection coat with an amount of coating of less than 2 mg/cm2 so as to achieve coating on an electron gun side surface of a shadow mask.

Abstract: A method for making a shadow mask array is taught. Producing a plurality of shadow mask sections; inspecting the plurality of shadow mask sections to determine which shadow mask sections are acceptable as meeting predetermined criteria; positioning a predetermined number of the acceptable mask sections into predetermined locations relative to one another to form a mask section array thereby distributing any error in individual mask sections across the mask section array; and attaching the individual mask sections of the mask section array to a support structure. The support structure allows for expansion and/or contraction of the individual mask sections of the mask section array while maintaining relative positioning of the individual shadow mask section in the shadow mask array. The support structure further allows for compliance of the shadow mask array in a direction normal to the plane of the shadow mask array thereby allowing for a substantially planar interface between the shadow mask array and a substrate to be coated.

Abstract: A cathode ray tube comprises a color selection electrode with a shadow mask fixed to a frame and put under tension. The frame comprises a bimetal element (or bimetal elements) which are constructed such that at a raised temperature the tension is released by reducing the distance between sides of the frame to which the mask is attached. The reduction in distance at the center of the sides exceeds, preferably by a factor 1.5 to 3, the reduction in distance at the corners of said sides.

Abstract: In a shadow mask color cathode ray tube, its shadow mask is not easily deformed into a concave shape when an impact or a vibration is applied to the shadow mask, so that a good image can be displayed. The electron beam passing holes of the shadow mask are each formed of an upper hole etched from the panel side of the shadow mask and a lower hole etched from the electron-gun side of the shadow mask. In each electron beam passing hole located in the peripheral portion of the shadow mask, the ratio of an upper-side etching quantity to a lower-side etching quantity is controlled to be 1.8 or less. By adjusting the balance in strength relative to compressive stresses between the panel side and the electron-gun side of the shadow mask, it is possible to prevent the shadow mask from being deformed into a concave shape.
