Abstract
본 발명은 슬릿보빈형 편향요크의 상하왜곡보정장치에 관한 것으로서, 보다 상세하게는 슬릿보빈형 편향요크에 자계보정용 보조 코일을 수평코일의 중앙부에 위치하도록 설치하여 전자빔의 미스 콘버젼스를 보정할 수 있도록 한 것이다.The present invention relates to a vertical distortion correction device for a slit bobbin type deflection yoke, and more particularly, to install a magnetic field correction auxiliary coil in a slit bobbin type deflection yoke so as to be located at the center of a horizontal coil to correct misconvergence of an electron beam. I would have to.
특징적인 구성으로는 기존의 제1수평코일의 권선 방향과 반대 방향으로 역권선한 제2수평코일을 상기 제1수평코일의 중앙부에 위치하도록 설치하고 상기 제2수평코일에 역권선되는 권선량을 조절하여 화면 중앙으로부터 주변으로 갈수록 수직 분력이 조절(증가)되는 수평 편향력을 발생시키도록 함에 있다.A characteristic configuration is to install a second horizontal coil reversely wound in a direction opposite to the winding direction of the existing first horizontal coil so as to be located at the center of the first horizontal coil, and the amount of winding reversely wound on the second horizontal coil. It is to generate a horizontal deflection force in which the vertical component is adjusted (increased) toward the periphery from the center of the screen.
