Abstract: An in-line electron gun includes an electron beam forming area formed with first and second grids, a main electrostatic focusing lens with first and second accelerating/focusing electrodes, and a shield cup. The first accelerating/focusing electrode is formed in a horizontally elongated rectangular hole and has an elliptical electrode in which electron beam passing holes are formed. The second accelerating/focusing electrode is formed in a horizontally elongated rectangular hole, and the shield cup has a bottom in which non-circular holes are formed.

Abstract: This invention relates to an inline electron gun for a color cathode ray tube, more particularly to an inline electron gun which can provide high resolution by controlling intensity of electrostatic lenses that controls electron beams according to intensity of current, dynamically.
