Abstract
An in-line electron gun for a color picture tube has an accelerating electrode portion separated into two or three electrodes in a triode, in which a voltage supplied to respective electrodes is varied and an asymmetrical hole is formed in at least one among the electrodes to form an additional asymmetric lens, thereby preventing degradation of a focus characteristic caused by an abrupt increase of a diverging angle of electron beam in a high current region, degradation in the vertical electron beam due to an influence of a magnetic field of a deflection yoke, change of focusing force induced by voltage variation of a first accelerating/focusing electrode, and degradation of the electron beam owing to collision/repulsion among electrons in the electron beam.
