Abstract

본 발명은 칼라 음극선관에 적용되는 전자총에 관한 것으로써, 좀더 구체적으로는 전단렌즈를 형성하는 제3전극의 구조를 개선하여 비대칭 전단렌즈의 종횡비를 크게하여 디프렛션 디포커싱현상을 보상할 수 있도록 한 것이다. 이를 위해, 전자빔(14)을 방사하는 복수개의 음극(2)일측에 상기 전자빔의 방사량조절 및 크로스오버를 형성하기 위한 제어전극과 가속전극 그리고 양극을 관충방향으로 순차 배열하여 스크린전체에서 균일한 포커스를 얻기 위해 전자빔(14)이 주렌즈로 입사하기 전에 전자빔의 인라인방향을 그에 수직한 방향보다 큰 횡장형으로 형성하도록 된 것에 있어서, 제2전극(4)과 제3전극(25)사이에 형성되는 전단렌즈(19)를 회전 비대칭으로 하기 위해 제3전극(25)중 제2전극(4)의 대향면(25d)에 인라인방향의 길이가 그에 수직한 방향보다 짧은 전자빔 통과공(25a)을 형성하여서 된 것이다.The present invention relates to an electron gun applied to a color cathode ray tube, and more specifically, to improve the structure of the third electrode forming the shear lens to increase the aspect ratio of the asymmetric shear lens to compensate for the deflection defocusing phenomenon. It would be. To this end, the control electrode, the acceleration electrode, and the anode are sequentially arranged in the tube-entry direction to control the radiation dose of the electron beam and form a crossover on one side of the plurality of cathodes 2 emitting the electron beam 14, thereby uniformly focusing the entire screen. In order to form an in-line direction of the electron beam in a horizontal shape larger than the direction perpendicular to it, before the electron beam 14 is incident on the main lens, it is formed between the second electrode 4 and the third electrode 25. In order to make the shear lens 19 asymmetrically rotated, an electron beam through hole 25a having a length in the inline direction shorter than a direction perpendicular to the opposite surface 25d of the second electrode 4 of the third electrodes 25 is provided. It was formed.
