ABSTRACT:
A cathode ray tube includes an electron gun for emitting an electronic beam, a deflection yoke which deflects the emitted electronic beam, and a corrector including electromagnets installed in the up-and-down and right-and-left sides of a separator of the deflection yoke for correcting the shape of the section of the emitted electronic beam. Resolution of the picture can be improved by correcting the distortion of the section of the electronic beam which is landed at the edge of a fluorescent film.
