Abstract
A Uni-Bipotential in-line electron gun for a color cathode ray tube includes a specially shaped G4 electrode for compensating the gun for comatic distortion. In the G4 electrodes the three apertures are oblong in shape, with the two outer apertures being horizontally displaced from the beam axis to inwardly displace the electron beams so that they substantially fall on the respective optical axes of symmetry of the main lens.
