Abstract: A 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. (Figures 1 and 2)

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: 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: An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.

Abstract: A color display system (9) includes a cathode-ray tube (10) and self-converging yoke (30) that produces an astigmatic magnetic deflection field within the tube. The gun (26) includes beam-forming region electrodes (34,36,38,40), main focusing lens electrodes (44,46), and two electrodes (42,44) for forming a multipole lens between the beam-forming region and the main focusing lens in each of the electron beam paths. Each multipole lens is oriented to provide a correction to an associated electron beam to at least partially compensate for the effect of the astigmatic magnetic deflection field on that beam. A first multipole lens electrode (42) is located between the beam-forming region electrodes and the main focusing lens electrodes. A second multipole electrode (44) is connected to a main focusing lens electrode and located between the first multipole lens electrode and the main focusing lens, adjacent to the first multipole lens electrode.

Abstract: The novel CRT is similar in structure to prior art CRT's except for the color-selection structure, which, as in the prior CRT's is for producing a plurality of lenses for passing and focusing portions of electron beams to associated color groups of the target. In the novel CRT, the color-selection structure comprises at least one lenticular member having therein an array of windows associated with only one color group, each window having a half-width, r, and a conductive mesh having interstitial dimensions small compared to the phosphor elements in the color groups. The lenticular member is longitudinally spaced a distance, s, from the conductive mesh so that the ratio of the longitudinal spacing, s, to the half-width, r, of the window is much less than unity (s/r
