摘要： An electron gun for a high resolution color display tube comprises three inline cathode assemblies, a control grid with three inline apertures, a screen grid with three inline apertures, a screen grid slot plate with three inline substantially rectangular slots each associated with a different one of the apertures in the screen grid, and a main electron lens. The screen grid slot plate is attached to the screen grid on the side thereof facing the main electron lens. Each of the cathode assemblies produces an electron beam having a given beam current. Each of the slots in the screen grid slot plate has an inline dimension and a transverse dimension which are selected for the given beam current to independently control the horizontal and vertical sizes of the spot produced by each of the electron beams at a distance from the electron gun.

摘要： The invention relates to incorporating improved beam shielding means into the unitized focusing electrode structure of a plural beam in-line color cathode ray tube electron gun assembly. At least a portion of the G3 electrode structure is fabricated of a magnetic alloy material. Positioned forward and adjacent to the magnetic portion is an apertured planar shielding means also fabricated of magnetic material. The cooperation of these adjoining magnetic areas provides significant shielding of the beams from the deleterious back-field of the deflection yoke.

摘要： An improved color display system includes a cathode-ray tube and a magnetic deflection yoke positioned on the tube. The tube includes an envelope having an inline electron gun for generating and directing three inline beams along initially coplanar paths toward a screen on an interior surface portion of the envelope. The gun includes a plurality of spaced electrodes which comprise three lenses. The first lens includes a beam-forming region for providing substantially symmetrical beams to a second lens. The second lens includes a first modulation electrode for providing asymmetrically-shaped beams to a third, or main, lens. At least one and preferably two dynamic voltage signals are applied to the modulation electrode of the second lens. Another dynamic voltage signal is applied to a second modulation electrode of the third lens. The voltage signals are related to the deflection of the beams and improve the electron beam spot size at the periphery of the tube screen.

摘要： The present invention provides an improvement in color cathode-ray tubes. Such tubes include an electron gun for generating and directing three inline beams, a center beam and two side beams, along initially coplanar paths toward a screen of the tube. The gun includes a plurality of spaced electrodes which provide a first, a second and a third lens for focusing the electron beams. The first lens has a beam forming region for providing substantially symmetrical beams to the second lens. The improvement comprises the combination of the second and third lens. The second lens includes at least one electrode to provide asymmetrically-shaped beams. The potentials applied to the second lens refract electron beams emerging off-axes from the first lens toward the axes. The third lens is a low aberration main focusing lens which provides asymmetrically-shaped beams of substantially constant current density to the screen.

摘要： The present invention provides an improvement in a color display system. The system includes a cathode-ray tube having an electron gun for generating and directing three electron beams along paths toward a screen of the tube. The gun includes electrodes comprising a beam forming region, electrodes for forming a prefocus lens and electrodes for forming a main focusing lens. The system also includes a magnetic field deflection yoke. The improvement comprises means for applying a dynamic signal to one of the electrodes forming the prefocus lens when electron beam current drops below a predetermined level. The dynamic signal is a maximum voltage when there is no deflection of the electron beams and decreases in voltage to a minimum at maximum horizontal deflection of the electron beams.

摘要： An improved method of making a color picture tube electron gun includes the selection and assembly of a plurality of cathodes and a plurality of electrodes longitudinally spaced from the cathodes. The improvement comprises at least three additional steps. First, the amount and direction of electron beam misconvergence at the tube screen, as caused by the thermal expansion of each individual electrode during electron gun warmup, is determined. A first group of electrodes will cause misconvergence in a first direction, and a second group of electrodes will cause misconvergence in a second direction. Second, the individual contributions of the electrodes to misconvergence during tube warmup are summed. The net effect of thermal expansion of the entire electron gun is a misconvergence in the first direction. Third, at least one of the electrodes in the first group of electrodes is formed from a material having a lower coefficient of thermal expansion than the coefficient of thermal expansion used in the first step of determining misconvergence caused by the thermal expansion of each individual electrode.
