칼러 음극 선관Color cathode ray tube

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 관계하는 일반형의 음극선관을 전반적으로 표시한 도면.1 is a view showing generally a cathode ray tube of a general type according to the present invention.

Claims (1)

1쌍의 장측과 1쌍의 단측을 지닌 페이스 플레이트, 페이스 플레이트에 연결되어 있는 제1개구 단부 및 제2개구 단부를 지닌 퍼늘, 퍼늘의 제2개구 단부에 연결되어 있는 네크, 페이스 플레이트의 단측에 나란한 방향으로 펼쳐 있으면서도 규칙적으로 정열된 다수의 인스트립들을 포함할 뿐만 아니라 페이스 플레이트에 코우팅되어 있는 인 스크리인, 다수의 전자 비임-이 전자 비임의 방향은 관축을 정의함-을 방출하기 위해 네크에 배치되어 있는 전자총, 전자비임을 통과시키도록 다수의 개구들을 지니면서 전자총과 인스크리인 사이에 위치한 색 선택전극, 그리고 스크리인을 주사하도록 전자비임을 편향하기 위한 편향장치, 그리고 퍼늘을 따라 뻗어있는 자기 시일드로 구성된 음극선관에 있어서, 페이스 플레이트의 단측에 대응하는 1쌍의 단측벽과 페이스 플레이트의 장측에 대응하는 1쌍의 장측벽으로 상기 내부 자기시일드를구성함으로서, 관축을 포함하면서도 페이스 플레이트의 장측에 나란한 제1가상면과 관축을 포함하면서도 페이스 플레이트의 단축에 나란한 제2가상면에 의해 정해지는 4부분을 상기 1쌍의 장측벽이 가지게 됨에 따라, 이들 4부분 각각이 전자비임이 상기 편향장치에 의해 편향될때 전자비임 방향을 따라서 적어도 1개의 가늘고 긴 개구를 지니는 바, 이 가늘고 긴 개구의 폭은 그 길이의 1/3미만 이고 이 개구의 중심은 상기 제2가상면쪽으로 상쇄되어져 나가는 특징을 지닌 칼러 음극선관.A face plate having a pair of long sides and a pair of short sides, a perimeter having a first opening end and a second opening end connected to the face plate, a neck connected to a second opening end of the perimeter, and a short side of the face plate. In order to emit a plurality of electron beams, the incidence of which defines the tube axis, which is an inscribed coating on the face plate, as well as containing a number of insulated and aligned in a parallel direction. An electron gun disposed in the neck, a color selection electrode located between the electron gun and the in-scree with a plurality of openings for passing the electron beam, a deflector for deflecting the electron beam to scan the screen and a perimeter A cathode ray tube composed of extending magnetic shields, comprising: a pair of short side walls corresponding to the short side of the face plate; By forming the inner magnetic shield with a pair of long side walls corresponding to the long side of the tooth plate, the first virtual surface including the tube axis and parallel to the short side of the face plate while including the tube axis parallel to the long side of the face plate. As the pair of long side walls have four portions defined by the surface, each of these four portions has at least one elongated opening along the electron beam direction when the electron beam is deflected by the deflector, A narrow cathode ray tube, characterized in that the width of the elongated opening is less than one third of its length and the center of the opening is offset toward the second virtual plane. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
