Abstract

본 발명은 인라인형 전자총의 특성 개선을 위해 일부 전극의 구조를 개량하는 칼라 수상관용 전자총의 전극구조에 관한 것이다.The present invention relates to an electrode structure of an electron gun for a color image sensor, which improves the structure of some electrodes in order to improve characteristics of an inline type electron gun.

본 발명은 칼라 수상관용 전자총에서 제3그리드(13) 및 제4그리드(14)의 대향하는 면에 형성되는 외주전극(13a)(14a) 중 적어도 한쪽의 것은 그 수직면이 반원 또는 호의 형태로 절개 또는 돌출되는 외주절개부(S)를 지니는 것을 특징으로 하는 칼라 수상관용 전자총을 제공하여, 주렌즈부의 전자빔 집속을 완화 및 4극자 효과를 강화시키고, 수상관의 외형치 수 변화없이도 구면수차, 화면주변부 포커스 특성 등을 향상시키는 효과가 있다.The present invention is characterized in that at least one of the outer circumferential electrodes 13a and 14a formed on the opposing surfaces of the third grid 13 and the fourth grid 14 in the electron gun for a color image pickup apparatus has a vertical surface in the form of a semi- Or the protruded outer cutout portion (S), so that the electron beam focusing of the main lens portion is alleviated, the quadrupole effect is enhanced, and the spherical aberration, the spherical aberration, and the spherical aberration The peripheral focus characteristic and the like are improved.
