Abstract
칼라 음극선관용 전자총은 칼라 영상을 형성하기 위한 칼라 성분을 각각 갖는 다수의 전자빔 통로를 제공한다.Electron guns for color cathode ray tubes provide a plurality of electron beam passages each having a color component for forming a color image.
본 발명의 전자총은 축방향으로 음극선관과 동축이고 수평방향에 대하여 서로 실제로 비대칭적인 한쌍의 전극을 구비한다.The electron gun of the present invention has a pair of electrodes coaxial with the cathode ray tube in the axial direction and actually asymmetric with each other in the horizontal direction.
각 전극은 한쌍의 전극을 구비한다.Each electrode has a pair of electrodes.
각 전극은 공통개공을 가진다.Each electrode has a common opening.
각 공통개공은 축방향으로 일정 거리로 떨어져 마주보도록 형성된다.Each common opening is formed to face away at a distance in the axial direction.
또한, 각 전극은 제1, 제2전극편을 구비한다.Moreover, each electrode is equipped with the 1st, 2nd electrode piece.
제1전극편은 축방향에서 전극의 공통 개공으로부터 일정거리로 떨어져 있다.The first electrode piece is spaced apart from the common opening of the electrode by a predetermined distance in the axial direction.
제1전극편은 수평방향에서 쇠사슬 고리상에 다수의 개공을 구비한다.The first electrode piece has a plurality of openings on the chain ring in the horizontal direction.
이들 개공은 서로 부분적으로 중첩되어 서로 집합적으로 연통하여 단일 개공을 형성한다.These openings partially overlap each other and collectively communicate with each other to form a single opening.
각 개공은 다수의 전자빔 각각에 대응한다.Each opening corresponds to each of the plurality of electron beams.
제2전극편은 축방향에서 일정거리를 두고 제1전극편으로 부터 이격되며 제1전극편보다 전극의 공통 개공으로 부터 더멀리 떨어져 있다.The second electrode piece is spaced apart from the first electrode piece at a predetermined distance in the axial direction and farther from the common opening of the electrode than the first electrode piece.
다르게는, 각 전극은 부분적으로 겹쳐지는 다수의 개공을 갖는 쇠사슬 고리상부재와 전극내측에 공통 개구주위로 부터 일정거리로 연장한 트랙부재를 가지고 전극의 공통 개구에 인접한 림과, 림으로 부터 일정거리로 떨어지고 전극내측에 배치된 제어전극편을 구비한다.Alternatively, each electrode has a rim adjacent to the common opening of the electrode with a chain annular member having a plurality of openings partially overlapped and a track member extending a predetermined distance from the periphery of the common opening inside the electrode, and constant from the rim. And a control electrode piece disposed at an inner side of the electrode at a distance.
