Abstract: A color display system includes a cathode-ray tube and a yoke. The yoke is a non-converging deflecting type. The cathode-ray tube has an electron gun for generating and directing three electron beams, a center beam and two outer beams, along paths toward a screen of the tube. The electron gun includes electrodes that comprise a beam-forming region and electrodes that form a main focusing lens. The main focusing lens is formed by at least two focusing electrodes. The focusing electrode closest to the beamforming region includes at least two laterally-spaced parts. Each spaced part forms a portion of a dipole lens structure in the path of an outer electron beam. Means are provided for applying to at least one of the spaced parts a dynamic signal which is related to the deflection of the electron beams.

Abstract: A color display system (9) includes a cathode-ray tube (10) and yoke (30). The yoke is a self-converging type that produces an astigmatic magnetic deflection field within the tube. The cathode-ray tube has an electron gun (26) for generating and directing three electron beams (28) along paths toward a screen (22) of the tube. The electron gun includes electrodes (34,36,38,40) that comprise a beam-forming region and electrodes (44,46) that form a main focusing lens, and features 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 field on the associated beam. There are two multipole lens electrodes. A second of the two multipole lens electrodes (44) is connected to and combined with a main focusing lens electrode (44), and a first of the two multipole lens electrodes (42) is located between the second multipole lens electrode and the beam-forming region and faces the second multipole lens electrode.

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.
