칼라 음극선관용 전자총Electron gun for colored cathode ray tube

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제5도는 본 발명에 따른 칼라 음극선관의 쉴드컵을 도시한 정면도, 제6도는 제5도에 도시된 필드 콘트롤러에 의해 형성된 자계분포를 가시화 시킨 자계분포도.5 is a front view showing a shield cup of a color cathode ray tube according to the present invention, and FIG. 6 is a magnetic field distribution diagram that visualizes a magnetic field distribution formed by the field controller shown in FIG.

Claims (1)

쉴드컵과 이 쉴드컵의 내면에 편향요오크의 누설자계의 영향으로 중앙의 전자빔과 사이드의 전자빔에 의해 스크린면에 형성된 칼라스터패턴의 불일치를 보정하는 라스터 패턴 보정수단을 포함하는 칼라음극선관의 전자총에 있어서, 상기 라스터패턴 보정수단이 상기 중앙의 전자빔통과공 상하부에 고정된 도넛형의 제1필드콘트롤러와, 상기 양 사이드의 전자빔통과공의 가장자리에 고정되며 그 내부직경이 상기 사이드의 전자빔통과공의 직경과 대략 동일하고 수평중심의 외측방향으로 소정곡률의 돌기부를 가지는 환형의 제2필드콘트로러를 구비하여 된 것을 특징으로 하는 칼라음극선관용 전자총.A color cathode ray tube comprising a shield cup and raster pattern correction means for correcting a mismatch between the color caster patterns formed on the screen surface by the electron beam at the center and the electron beam at the side under the influence of the leakage magnetic field of the deflection yoke on the inner surface of the shield cup. In the electron gun of the raster pattern correction means is a donut-shaped first field controller fixed to the upper and lower portions of the electron beam through hole in the center, and fixed to the edges of the electron beam through hole of the both sides, the inner diameter of the side An electron gun for a color cathode ray tube, comprising: an annular second field controller having a projection having a predetermined curvature in the outward direction of the horizontal center, substantially equal to the diameter of the electron beam passing hole. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
