摘要： A color picture tube apparatus comprises an envelope including a funnel, a face plate and a neck, a phosphor screen on an inner surface of the face plate, an electron gun structure in the neck of the envelope for generating at least one electron beam, resistor means for supplying predetermined voltage to the electron gun structure, and deflection means for generating non-uniform deflection magnetic field to deflect the electron beam. The electron gun structure includes a focusing electrode including first means for generating an asymmetric converging electric field near the focusing electrode having a relative strong converging action in one direction compared with the converging action in another direction perpendicular to the one direction, an accelerating electrode including second means for generating an asymmetric diverging electric field near the accelerating electrode having a relative strong diverging action in the one direction compared with the diverging action in the other direction, and at least one intermediate electrode between the focusing electrode and the accelerating electrode for separating the converging electric field from the diverging electric field.

摘要： A color display system includes a cathode-ray tube and yoke. The yoke is a non-converging 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 beam-forming region includes at least two 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.

摘要： In a color cathode ray tube having an in-line electron gun with overlapping CFF lenses, the small openings of the focusing electrode apertures are critically enlarged to balance the asymmetry of the lensing field caused by the overlap, and beam spot distortion due to field asymmetries in the focus region is eliminated. Enlargement is achieved by elongating the openings in a direction normal to the in-line plane, and widening the outer openings.

摘要： An improved color picture tube has an inline electron gun for generating and directing three electron beams, a center beam and two side beams, along coplanar paths toward a screen of the tube. The gun includes a main focusing lens for focusing the electron beams. The main focusing lens is formed by two spaced electrodes, each having three separate inline apertures therein. Each electrode also includes a peripheral rim. The peripheral rims of the two electrodes face each other. The apertured portion of each electrode is within a recess set back from the rim. The recesses of the electrodes have substantially the same dimension perpendicular to the inline directions of the inline apertures as the dimension parallel to the inline direction of the inline apertures. However, the recesses have lesser dimensions along diagonals angled at approximately 45 degrees with respect to the inline direction of the inline apertures. The electrodes are connected by four support rods that are peripherally attached to the electrodes along the diagonals.

摘要： A cathode ray tube is provided having an electron gun equipped with a main lens having a function of controlling a shape of an electron beam spot which is deflected to the peripheral portion of a display screen, to improve a resolution at the peripheral portion of the screen of the cathode ray tube for use in a direct view color television receiver or a color display terminal. To reduce the dynamic correction voltage of the electron gun, an electrostatic quadrupole lens with a simple structure is used, thereby reducing deterioration due to the deflection aberration of the electron beam spot at the peripheral portion of the screen.
