摘要: Colour display tube comprising an electron gun (5) for producing three co-planar electron beams (6,7,8), and including a deflection system which, in operation, generates deflection fields of the self-convergent type, with three consecutive elements (14,14',14") influencing convergence being arranged between the electron gun (5) and the display screen (2), the two outer elements producing, in operation, opposite effects and the central element being energizable for correcting remaining convergence errors.
