Abstract: CRT comprises a color-selection structure for producing a plurality of quadrupolar lenses, each lens defining a window for passing and focusing portions of electron beams to an associated color group of a target. The color-selection structure comprises (i) a metal masking plate having therein an array of substantially rectangular windows, each window having associated therewith (ii) a pair of first conductors insulatingly spaced from one major surface of the plate and located adjacent opposite sides of the aperture and (iii) a pair of second conductors insulatingly spaced from the other major surface of the plate and located adjacent opposte sides of the window. The CRT includes means for applying a voltage to said plate, means for applying a voltage to said pairs of first conductors and means for applying a voltage to said pairs of second conductors.

Abstract: In a display device having an evacuated envelope, an electron beam guide and an electron generating means for generating beams of electrons, a modulator structure on which is disposed a plurality of control electrodes may be formed by interconnecting selected ones of the control electrodes which operate at a common potential. This interconnected electrode structure decreases the number of control electrodes which extend from the evacuated envelope. The electron generating means is shielded from the interconnected electrode structure to prevent perturbation of the generated electron beams.

Abstract: A CRT comprises a deflection-and-focus color-selection masking structure, a screen of parallel phosphor stripes, and means for producing three convergent in-line electron beams directed towards the target. The masking structure comprises a metal masking plate having two major surfaces and having therein an array of apertures arranged in columns that are substantially parallel to the phosphor stripes. Arrays of narrow conductors are insulatingly supported in opposed positions on each major surface of said plate. The conductors extend substantially parallel to the stripes and are located in every other space between the columns.

Abstract: The structure comprises an evacuated envelope that includes a transparent front panel having a cathodoluminescent screen thereon and a back panel interconnectably sealed to the front panel. A plurality of first vanes, spaced from and parallel to each other, are perpendicular to and in contact with the back panel and a plurality of second vanes, spaced from and parallel to each other, are perpendicular to and in contact with the front panel. The first and second vanes are transverse to each other and provide mutual support for each other. Electroding to control operation of the device is formed directly on the vanes.

Abstract: An electron gun for use in a cathode ray tube includes beam forming electrodes and beam focusing electrodes. A gun improvement comprises the beam forming electrodes including a cathode, a control grid adjacent to the cathode and two screen grids. A first screen grid is located adjacent to the control grid. A second screen grid is located between the first screen grid and the beam focusing electrodes. Preferably, the second screen grid and the control grid are grounded.

Abstract: CPT comprises a deflection-and-focus color-selection masking structure, a screen of parallel phosphor stripes, and means for producing three convergent in-line electron beams directed towards the target. When the CPT is operated, pairs of beamlets transmitted through windows in adjacent apertures in the masking structure are deflected towards one another to excite the same phosphor stripe and, also, are focused (compressed) in the narrow width direction of the phosphor stripes and defocused (stretched) in the length direction of the phosphor stripes.
