Abstract

본 발명은 음극선관용 전자총을 개시한다.The present invention discloses an electron gun for a cathode ray tube.

본 발명은 적, 녹, 청색신호의 전자빔이 공히 통과하며 상기 녹색전자빔신호의 전자빔이 통과하는 중앙부의 가장자리가 소정의 폭으로 돌출된 돌출부를 가지는 대구경 전자빔통과공이 형성된 제1전극부재와, 상기 제1전극의 내부에 고정설치되며 세개의 독립소구경 전자빔통과공이 형성된 제2전극 부재를 포함하여 된 음극선관용 전자총에 관한 것으로, 상기 독립 소구경 전자빔 통과공의 이심거리를 S라 하고 양측 독립 소구경 전자빔통과공의 중심이 이로부터 중앙의 독립 소구경 전자빔 통과공측으로 이동한 거리를 A라 할 때에 이 A의 값이 부동식 0.15S＜A＜0.35S를 만족하는 것에 특징이 있으며, 이는 전 형광막에 랜딩되는 전자빔 스프트를 균일하게 할 수 있어 이를 채용한 음극선관의 해상도를 향상시킬수 있는 이점을 가진다.According to the present invention, a first electrode member having a large-diameter electron beam passing hole having a protrusion in which a center portion through which an electron beam of red, green, and blue signals passes and protruding a predetermined width of a central portion through which the electron beam of the green electron beam signal passes is formed; The present invention relates to a cathode ray tube electron gun fixed to an inside of an electrode and including a second electrode member having three independent small diameter electron beam through holes, wherein the eccentric distance of the independent small diameter electron beam through holes is S and both independent small diameters When the center of the electron beam passing hole moves from this to the independent small-diameter electron beam passing hole at the center, A is characterized by that the value of A satisfies the floating type 0.15S <A <0.35S. The electron beam shaft landing on the film can be made uniform, which has the advantage of improving the resolution of the cathode ray tube employing the same.
