Abstract:
An electron beam deflection system positioned outside of a main body of a color tube having a neck, inside of which electron beams are arranged in a horizontal direction, and a display unit extended from the neck in its diameter for displaying images by means of electron beams scanned from the electron beams and comprising:a pair of horizontal deflection coils arranged to face each other in a vertical direction; a pair of vertical deflection coils arranged to face each other in a vertical direction; a pair of vertical deflection coils arranged to face each other in a vertical direction; a pair of coils arranged to face each other in a vertical direction outside of the neck with the neck between them, each of the coils including a correction coil in a diametric direction of the neck for generating a magnetic field in an opposite direction to the direction of the other coil for correcting a YV aberration.
