Title: Electron gun for color cathode-ray tube
Inventor: SEKI TAKAYUKI
IPC: H01J29/48
Filed: 1988-02-26
Abstract: PURPOSE:To improve the focusing characteristic by expanding the electric field of electron beam passing areas on both side more than the electric field of the electron beam passing area at the center and moderating the potential distribution in an auxiliary focusing lens arranged between a main focusing lens and a pre-focusing lens. CONSTITUTION:The adequate electric field is formed by a main focusing lens constituted of the fifth and sixth electrodes 5 and 6 so that both side electron beams BS1 and BS2 emitted from an electron gun 22 on a fluorescent screen 23 are self- concentrated. The vicinity of the periphery of both side electron beam passing holes of the fourth grid electrode 4 forming an auxiliary focusing lens is recessed, the thickness of the electrode on the periphery of both side electron beam passing holes is made thinner than that for the center electron beam. According to this means, the electric field of both side electron beam passing areas of the auxiliary focusing lens is expanded, the potential distribution is moderated, the effective lens diameter is increased. In the main focusing lens, both side electron beams are focused by the stronger electric field than the electric field for the center electron beam, astigmatism correction is performed without impairing the self-concentration function, and the focusing performance can be improved.
