摘要： A cathode ray tube includes an electron gun directing electrons away from a faceplate having an electrode biased at screen potential. A plurality of electrodes located on or near the rear wall of the tube envelope are biased at graduated potentials so that the electron beam is deflected by the electrostatic field produced thereby to impinge upon the faceplate. The electron beam is magnetically deflected over a relatively small angle as it exits the electron gun to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. The electrodes may be biased at or below screen potential, with the electrode closest the electron gun typically biased at a negative or ground potential and the electrode closest the faceplate (i.e. distal the electron gun) typically biased below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle thereof.

摘要： A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. A neck electrode near the tube neck is biased at or below screen potential and a second electrode between the neck electrode and the faceplate is biased at or above screen potential. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection. A third electrode proximate the faceplate is biased at or below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle of the electrons thereon. A metal and ceramic support includes a resistive voltage divider to which ones of the electrodes connect.

摘要： A plural-beam cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon a pattern of phosphors thereon to produce light of different colors depicting an image. A first conductive coating near the tube neck is biased below screen potential and a second conductive coating between the neck electrode and the faceplate is biased at screen potential. A gap between the first and second conductive coatings varies in distance from the faceplate so as to be non-Z-planar. The non-Z-planar gap is preferably partly within the region wherein electrons are deflected by the magnetic deflection yoke and partly more proximate the faceplate than such deflection region.

摘要： A cathode ray tube includes an electron gun directing electrons away from a faceplate having an electrode biased at screen potential. One or more electromagnets located on or near the rear wall of the tube envelope are biased with dc currents so that the electron beam (three beams in a color tube) is deflected by the magnetic field produced thereby to impinge upon the faceplate. The electron beam is magnetically deflected over a relatively small angle as it exits the electron gun to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. The electromagnet closest the electron gun is typically biased to produce a strong magnetic field to deflect electrons to the faceplate near to the electron gun. The electromagnets more distant the electron gun produce magnetic fields to direct electrons towards the faceplate, with the electromagnet most distant the electron gun deflecting the electrons to tend to increase the landing angle thereof on the faceplate. One or more of the foregoing electromagnets may be utilized in cooperation with one or more electrodes biased at a potential to similarly deflect the electrons to the faceplate.

摘要： A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam (three beams in a color tube) is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. A first pair of electromagnetic coils forward of the tube neck and deflection yoke is biased by a substantially constant current level to further deflect the electron beam. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection yoke alone. A further pair of electromagnetic coils proximate the faceplate is biased by an oppositely poled substantially constant current level to direct electrons towards the faceplate, thereby to increase the landing angle of the electrons thereon.

摘要： A cathode ray tube deflection yoke is provided wherein the deflection yoke includes a plurality of deflection coils. One or more of the deflection coils have a non-constant distribution of turns, whereby an electron beam passing through the deflection yoke is deflected by a magnetic field that varies according to different numbers of turns relative to position of electrons of the electron beam between the entrance and exit of the deflection yoke. The non-constant turns distribution may be linear or non-linear, may be monotonic or non-monotonic, and/or may have a positive or negative turns bias, either in whole or in part. The horizontal deflection coil and/or the vertical deflection coil, or both, may have a non-constant turns distribution.
