Abstract

음극선관용 전자 빔 편향 장치에서 수평 편향 코일은 주 권선(21)과, 이 주 권선앞에 위치된 보조 권선(22)으로 구성되고, 보조 권선의 전류는 주 권선 전류의 순환 방향과 반대 방향으로 순환한다. 이러한 유형의 편향장치는 권선에 의해 생성된 자계의 2차 고조파의 진폭은 국부적으로 증폭시키는데 반해 4차 고조파의 진폭은 감소시킨다. 따라서, 본 발명의 편향 장치는 스크린 표면 전체에 걸쳐 빔의 집속을 유지하면서 기하학적 북/남으로 보정되게 된다.In the electron beam deflection apparatus for a cathode ray tube, the horizontal deflection coil is composed of a main winding 21 and an auxiliary winding 22 located in front of the main winding, and the current of the auxiliary winding circulates in a direction opposite to the circulation direction of the main winding current. . This type of deflector reduces the amplitude of the fourth harmonic while locally amplifying the amplitude of the second harmonic of the magnetic field produced by the winding. Thus, the deflection apparatus of the present invention is corrected to geometric north / south while maintaining the focus of the beam over the entire screen surface.

상기 장치는 특히 이미지 스크린이 명확한 곡률 반경을 갖는 음극선관에 채용된다.The device is particularly employed in cathode ray tubes in which the image screen has a definite radius of curvature.
