Abstract
A deflection yoke mounted on a rear portion of a cathode ray tube (CRT) to deflect an electron beam emitted from an electron gun of the CRT includes a coil separator mounted on the CRT, a horizontal deflection coil mounted on an inside of the coil separator, having a first section generating a horizontal deflection magnetic field deflecting the electron in a horizontal direction and having a first radius, having a second section generating a magnetic field to weaken the horizontal deflection magnetic field and having a second radius different from the first radius, a vertical deflection coil mounted on an outside of the coil separator and generating a vertical deflection magnetic field deflecting the electron beam in a vertical direction, and a ferrite core covering a portion of the vertical deflection coil to strengthen the horizontal deflection magnetic field and the vertical deflection magnetic field. Since the magnetic field of the second section is weakened, a beam strike neck (BSN) distance is improved, and a deflection sensitivity is improved.
