Abstract

본 발명은 브라운관 편향요크의 상하 왜곡을 보정하기 위한 왜곡 보정용 보조 코일의 권선에 관한 것으로서, 특히 인라인 전자총을 가지는 칼라 브라운관용 편향 요크의 수평 편향 코일에 관한 것이다. 종래의 평면 칼라 브라운관의 경우 상하 핀쿠션형 왜곡은 편향 요크에서 보정할 수 없고 샤시에서 전자회로로 보정을 하고 있다.The present invention relates to a winding of an auxiliary coil for distortion correction for correcting vertical distortion of a cathode ray tube deflection yoke, and more particularly to a horizontal deflection coil of a deflection yoke for a color brown tube having an inline electron gun. In the case of a conventional flat color cathode ray tube, the upper and lower pincushion distortion can not be corrected by the deflection yoke, and the correction is made from the chassis to the electronic circuit.

본 발명은 브라운관 홀더의 중간부에서 개구부까지 코일을 권선함에 있어서 상기 개구부쪽 코일은 수평 코일과 반대 방향으로 권선하여 수평 코일의 자계장 방향과 반대 방향의 자계장을 구성하고, 상기 중간부쪽 코일은 수평 코일과 같은 방향으로 권선하여 수평 코일의 자계장과 같은 방향의 자계장을 구성함으로써, 코일의 형상에 제한받지 않고 설계하고자 하는 자계장을 쉽게 만들 수 있게 하여 평면 칼라 브라운관에서 상하 핀쿠션형 왜곡을 편향 요크에서 상하 핀쿠션 왜곡 보정용 코일을 이용해서 보정할 수 있도록 한 브라운관 편향요크의 상하 왜곡 보정 코일의 권선 구조를 제공함 한다.The present invention is characterized in that, in winding a coil from an intermediate portion to an opening portion of a cathode ray tube holder, the opening side coil is wound in a direction opposite to the horizontal coil to constitute a magnetic field in a direction opposite to the magnetic field direction of the horizontal coil, By constructing the magnetic field in the same direction as the magnetic field of the horizontal coil by winding in the same direction as the horizontal coil, it is possible to easily create the magnetic field device to be designed without being limited by the shape of the coil, so that the upper and lower pincushion distortion There is provided a winding structure of a vertical distortion correcting coil of a cathode ray tube deflection yoke which can be corrected by using a coil for vertical pincushion distortion correction in a deflection yoke.
