Abstract
A thin cathode ray tube. A low voltage is applied to a beam of electrons produced by an electron gun. The electron beam is electromagnetically deflected through a large angle. Four static deflectors are used to deflect and accelerate the beam of electrons, and to let the beam of electrons have a sufficient energy level when it reaches a fluorescent screen. The cathode ray tube can effectively increase the deflection angle of the beam of electrons and reduce an incident angle of the beam of electrons so as to reproduce an image with less distortion.
