摘要： A cathode ray tube is constructed such that a resistance of a first conductive element connected to a metal film on the inner side of the panel is lower than a resistance of a second conductive element connected to a shadow mask. Thus, the amount of electrons which are emitted from an electron gun to strike the metal film increases, to thereby enhance luminance, and the amount of electrons striking the shadow mask is decreased, to thereby reduce thermal deformation of the shadow mask.

摘要： The present invention provides a method of making a tensioned focus mask. Such a mask includes a set of parallel strands and a set of parallel wires that are perpendicular to the strands and separated from the strands by insulator means. The method includes attaching the strands to a mask frame and then coating the strands with a first insulator. The first insulator is then cured, and a second insulator is applied to the first insulator. Next, wires are wound over and in contact with the second insulator, by rotating the mask frame and by drawing a continuous wire from a source through a tensioner, while guiding the continuous wire into desired positions overlying the strands. Finally, the second insulator is heated until the wires attach to the second insulator.

摘要： A CRT has an Einzel lens focus mask with a high voltage between the shadow mask and the meshes to achieve a strong focusing action and therefore minimize beam current interception by the shadow mask. The mask is supported by an insulating block inside a tube. During gettering, the getter material does not deposit on the inside of the tube and therefore spurious conduction paths are avoided. Thus the support can withstand the high voltage. A lead-in wire for the mask has a tube surrounding it which is open near the mask. This also withstands the high voltage.

摘要： In a color display tube of the post focusing type, the color selection structure (7) includes first lens electrode means (11) and second lens electrode means (12) situated at a short distance from each other. The second lens electrode means has a number of elongate conductors (12) or groups of conductors (12) extending parallel to each other. The conductors (12) or groups of conductors (12) are interconnected via a resistance material (19) as a result of which the energy released in an electric flash-over between the lens electrode means (11) and a conductor (12) in the flash-over point per unit of time is so small that the color selection structure (7) is not seriously damaged.

摘要： CRT employs a quadrupolar-focusing color-selection structure comprising two or more apertured masking plates. Each plate has therein an array of substantially rectangular apertures which are positioned relative to one another to produce electrostatic quadrupolar-focusing lenses when operating voltages are applied thereto. The color-selection structure may, by its geometry, provide at the same time electrostatic dipolar deflecting fields when operating voltages are applied.

摘要： Disclosed is a color display tube having a color selection electrode comprised of a metal plate having a large number of apertures and a plurality of elongated conductors insulated from the plate which extend across the apertures and divide them into two substantially symmetrical halves. Upon application of a suitable potential difference between the conductors and the plate, electric fields are produced in the apertures which deflect the portions of the beam passing through the respective aperture halves towards each other forming on the display screen a single, overlapping electron spot of a width smaller than that of the aperture.
