Abstract
본 발명은 칼라수상관에 설치사용되는 전자총에 관한 것으로서, 더 자세하게는 주렌즈인 포커스전극콰 애노드 전극 사이에 하나 또는 그 이상 설치되는 중간전극에 관한 것이다. 종래, 저전압이 인가되는 포커스전극(14)과 고전압이 인가되는 애노드전극(15)의 진압차를 해소하기 위하여 설치된 중간진극(17)의 구조가 제2도와 같이 소정두께의 판상에 하나외 타원형상의 전자비임퉁과공(17a)이 직각으로 천공되어 있어서 전자비임에 의해 형성된 전계의 급격한 굴곡으로 인해서 형광면의 소망하는 한 점에서 전자비임이 정확히 랜딩되지 못하고 타색을 침범하여 화면주변부에서 컨버전그 특성의 열화를 초래하는 문제점이 있었다. 따라서 본 발명의 목적은 종래의 이러한 문제점을 감안하여 전자비임에 의해 발생한 전계분포가 중간전극에서 완만한 형상을 이루도록 하여 전자비임이 형광면의 소망하는 한 점에 최적의 상태로 포커싱되도록 함으로써 정전렌즈에 의한 과집속을 막아 수상관의 전자비임 이 좁아지도록해서 화상을 선명하게 하는 포커스 특성 및 스크린의 품위를 향상시킨 칼라수상관용 전자총을 제공함에 있으며, 이러한 목적을 달성하기 위한 본 발명은 판상의 중간 전극에 타원형상의 전자비임통과공 하나를 형성하되, 판상의 중간전극에 소정크기의 오목부를 형성한 후 이들 오목부의 동심측선상에 전자비임통과 공을 형성하여서 된 것이다.The present invention relates to an electron gun used for installation in a color receiving tube, and more particularly, to an intermediate electrode provided between one or more focusing electrodes, a main lens, and an anode electrode. Conventionally, the structure of the intermediate electrode 17 provided to solve the suppression difference between the focus electrode 14 to which low voltage is applied and the anode electrode 15 to which high voltage is applied is one elliptical shape on a plate having a predetermined thickness as shown in FIG. Because the electron beam hole 17a is drilled at right angles, the electron beam cannot be landed exactly at the desired point of the fluorescent screen due to the sudden bending of the electric field formed by the electron beam, and it violates other colors, causing the convergence characteristic to be around the screen. There was a problem causing deterioration. Accordingly, an object of the present invention is to provide an electrostatic lens by focusing on an optimal point at a desired point of a fluorescent surface by allowing the electric field distribution generated by the electron beam to form a gentle shape in the intermediate electrode in view of such a conventional problem. The present invention provides a color water tube electron gun having a focus characteristic for sharpening an image and improving the quality of a screen by preventing an electron beam of a water tube to be narrowed by preventing excessive focusing. An elliptical electron beam through hole is formed in the cavity, and a recess having a predetermined size is formed in the plate-shaped intermediate electrode, and then an electron beam through hole is formed on the concentric side line of the recess.
