Abstract: A pair of four-pole magnet rings, each mounted for independent, concentric rotational adjustment about the neck of an in-line, tri-beam shadow-mask color kinescope, constitute a facility for introducing mutually opposing shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central, axial beam, and without requiring internal pole piece structures for field directing purposes. A pair of 6pole magnet rings, each mounted for independent, concentric rotational adjustment about an adjacent region of the color kinescope neck, constitute an additional facility for introducing like-direction shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central beam, and without requiring internal pole piece structures for field directing purposes. The two magnet ring pairs together provide an arrangement for effecting static convergence of the beam trio at the kinescope screen. A third pair of two-pole magnet rings, similarly subject to rotational adjustment about the kinescope neck, provide means for introducing like-direction shifts of all three beams in any desired direction for conventional purity adjustment purposes. In a preferred application of the invention, the two-pole ring pair, six-pole ring pair and four-pole ring pair, appear in axially spaced relation of a common mount surrounding the kinescope neck to the rear of a deflection yoke (with the ring pairs in the order named, progressing from the neck base toward the yoke rear) and constitute the only neck components (exclusive of the deflection yoke) required in set-up and operation of the color kinescope.

Abstract: In a color television display system in which a plurality of horizontal in-line electron beams are directed toward color phosphor elements of a color picture tube, substantial convergence of the beams at all points on a scanned raster is achieved by transversely positioning the deflection yoke relative to the picture tube while maintaining substantial parallelism between the central longitudinal axes of the yoke and picture tube.

Abstract: The problem of moire is eliminated by randomizing the vertical and horizontal pattern of webs between apertures of a shadow mask. A cathode ray tube is provided having a color phosphor screen structure comprising a plurality of arrays of substantially parallel lines. The lines in each array are adapted to emit light of a particular color. A shadow mask, having a plurality of substantially parallel rows of apertures that are elongated in the direction of the rows and separated from adjacent apertures in each row by webs, is spaced from the screen. The webs are randomly spaced along each row and the webs in adjacent rows are randomly displaced from one another in the direction of the rows. Alternatively, the web spacing in each row can be uniform and the rows randomly displaced from one another in the direction of the rows.
