摘要： A color cathode ray unit which includes an in-line type electron gun, a deflection yoke disposed on the color CRT so as to generate substantially uniform horizontal and vertical deflection magnetic fields, thereby ensuring that an axially unsymmetrical lens electric field is dynamically generated between a first and a second focusing grid thereby correcting a distortion of electron beams caused by a magnetic field leaking from a dynamic convergence means.
