Abstract
In a deflection yoke for a braun tube deflecting an electron beam radiated from an electron gun to a screen and including a horizontal deflection coil, a vertical deflection coil and a ferrite core, the horizontal deflection coil is installed inside a funnel, the ferrite core is installed outside of the funnel, the vertical deflection coil is installed inside or outside of the funnel, accordingly the convergence and deflection sensitivity of an electron beam can be easily compensated, the deflection sensitivity of a braun tube can improve, and the degree of freedom in designing the deflection yoke and an electron gun related to enlarging a diameter of the electron gun can increase.
