摘要： There is provided a cathode ray tube capable of displaying high quality images by suppressing eddy current from occurring and by realizing the velocity modulation. A cylindrical focusing electrode (4) is divided into first cylindrical focusing electrode (4B) and second cylindrical focusing electrode (4T) and the gap between the both electrodes formed and divided by optimizing the length of the second cylindrical focusing electrode (4T) in the tube axial direction is enlarged substantially to increase the infiltration of the velocity modulating magnetic field to the non-electric space of the focusing electrode (4). A plate electrode (4a) having equal potential with the focusing electrode (4) is disposed at the gap to suppress eddy current from being generated.

摘要： 전자빔을 CRT 디스플레이 화면에 동시에 접속 및 편향시키기 위해 음극선관(CRT)용 전자총은 음극, 저전압 빔 형성 구역(BFR) 및 CRT 자기 편향 요크의 빔편향 구역에 배치된 고전압 편향 초점 렌즈를 포함한다. 편향 렌즈는 각기 해당 빔 통과 개구를 가진 간격이 있는 첫번째 한쌍의 그리드를 포함하는 CRT 의 목 부분에 배치된 다수의 첫번째 초점 그리드를 포함하는데, 빔 통과 개구중 하나는 수평으로 오프셋되며 다른 빔 통과 개구는 전자빔 축으로부터 수직으로 오프셋된다. 첫번째 그리드 한쌍 각각의 반대편에 배치된 기타 그리드는 전자빔 축에 중심을 둔 해당 빔 통과 개구를 가지며 고정 초점 전압으로 유지된다. CRT 면판의 모든 지점에서의 비대칭 축외 전자빔 초점 이탈을 보상하기 위해 전자빔 편향과 더불어 변화하는 동적 초점 보정 전압이 첫번째 쌍 그리드 각각에 가해진다. 본 동적 축외 초점 이탈 보정은 멀티빔 컬러 편향 렌즈 CRT 뿐만 아니라 싱글빔 흑백 편향 렌즈 CRT 에도 똑같이 적용된다.
