Abstract

PURPOSE:To improve the convergence characteristic by forming at least 4 magnetic pole magnet in color purity regulating magnet, beam focusing 4 and 6 magnetic pole magnets with a coil connected to the external power source. CONSTITUTION:A picture tube 1 to be mounted on an air plane has a deflection yoke 2 mounted on a cone section, color purity regulating magnet and beam focusing 4 and 6 pole magnets mounted on the outside of an electron gun and covered with a shield 4 through a filled resin 5. Here the 4 pole magnet is formed as a coil (L) for forming 4 magnetic pole and connected to the external power source (E). When supplying the current through said coil (L), the misconvergence due to the insufficient heat run of the electron gun or the shifting of the focus voltage during the focus regulation can be easily corrected even after the filling of the resin 5, thereby it is applicable to such as an air plane where the requirement is strict.
