Abstract

본 발명은 칼라브라운관용 전자총에 관한 것으로, 주전극의 구조를 개선하여 화면부의 대형화 및 횡장화에 따라 포커스 특성이 열화되는 것을 방지할 수 있도록 한 것이다. 종래에는 주전극의 수직방향 직경이 수평방향 직경에 대비하여 42% 정도밖에 되지 않았기 때문에 발생되는 비점수차를 제거하기 위해 상기 주전극 내에 전자빔 통과공이 종장화 된 별도의 보조전극을 형성시켰으므로 생산성이 저하되었음은 물론 보조전극의 미소변형에 따른 조립정밀도가 저하되는 문제점이 있었다.The present invention relates to an electron gun for a color brown tube, and to improve the structure of the main electrode to prevent the deterioration of focus characteristics due to the enlargement and horizontal enlargement of the screen portion. Conventionally, since the vertical diameter of the main electrode is only about 42% of the horizontal diameter, a separate auxiliary electrode having an electron beam passing hole is formed in the main electrode to eliminate astigmatism. Of course, there was a problem in that the assembly precision was reduced due to the micro deformation of the auxiliary electrode.

본 발명은 이를 개선하기 위해, 3개의 전자빔 통과공(7)이 일체로 형성되는 전극(6)과, 상기 전극의 스크린면으로 고정되며 상하부가 만곡되는 수직방향직경(B')을 가진 주렌즈전극(8)을 포함하여 된 것이다.In order to improve the present invention, the main lens has an electrode 6 in which three electron beam through holes 7 are integrally formed, and a vertical diameter B ′ fixed to the screen surface of the electrode and curved up and down. The electrode 8 is included.
