Abstract

본 발명은 대형 TV 또는 고정세도 모니터에 사용되는 칼라 수상관의 화면 주변부의 해상도 열화를 방지하기 위한 칼라 수상관을 전자총에 관한 것으로 이와 같은 목적을 달성하기 위한 전자총의 구성은, 열전자를 방출하는 다수개의 캐소우드와, 열전자를 제어하는 제어전극과, 열전자를 가속시키는 가속전극과, 열전자를 접속시키는 포커스 전극과, 양극, 쉴드 컵이 일렬로 배열되어 봉상의 절연물에 고정되고, 상기 포커스 전극은 2분할 되어 그 사이에 일정한 간격을 유지하며 3개의 4극자 렌즈구성전극이 삽입되어 4극자 렌즈계를 형성하여 구성되어 있다.The present invention relates to a color receiving tube for preventing resolution degradation of the periphery of the screen of the color receiving tube used in a large-sized TV or high-definition monitor, and relates to an electron gun. Two cathodes, a control electrode for controlling the hot electrons, an acceleration electrode for accelerating the hot electrons, a focus electrode for connecting the hot electrons, an anode, and a shield cup are arranged in a row and fixed to the rod-shaped insulator, and the focus electrode is 2 It is divided into three four-pole lens configuration electrodes are inserted to maintain a constant interval therebetween to form a four-pole lens system.
