Abstract

미스컨버젼스 보정장치는 화면의 우측에는 적색빔이 많이 편향되고 화면의 좌측에는 청색빔이 많이 편향되어 발생된 미스컨버젼스를 보정하기 위하여 화면의 좌우측에서 발생한 미스컨버젼스와 동일한 크기와 형태를 갖는 미스컨버젼스를 화면의 중앙부위에도 강제로 발생시킨 후 수직편향코일에서 발생되는 수직편향자계를 이용하여 화면의 좌우측과 중앙부위에 발생된 미스컨버젼스를 동시에 보정하도록 한 것으로서, 화면의 중앙부위 상측에서 발생되는 보정자계와 하측에서 발생되는 보정자계간의 상호간섭을 방지하고, 각각의 보정자계를 충분히 크게 발생시키도록 하기 위하여 상측편향시에는 하측 코마프리 코일에서 발생된 자계를 상쇄시키고 하측편향시에는 상측코마프리 코일에서 발생된 자계를 상쇄시키도록 상측 코마프리 코일과 하측 코마프리 코일에 각각 직렬연결된 한쌍의 드럼코어와 보정코일을 상호 병렬구성하고, 자화된 면이 각각의 드럼코어와 마주보도록 각각의 드럼코어 사이에 자성체를 장착하였다. 이것은 모든 평향요크에 사용가능하고, 특히 화면의 좌측과 우측에서 적색빔과 청색빔이 각각 어긋나게 주사되는 미스컨버젼스가 발생된 편향요크에 매우 유용하다.The misconvergence correction device has a misconvergence having the same size and shape as the misconvergence generated on the left and right sides of the screen in order to correct misconvergence caused by a large deflection of the red beam on the right side of the screen and a large deflection of the blue beam on the left side of the screen. It is forcibly generated at the center of the screen, and then used to correct the misconvergence generated at the left and right sides and the center of the screen by using the vertical deflection magnetic field generated by the vertical deflection coil. In order to prevent mutual interference between the correction magnetic fields generated at the lower side and to generate each correction magnetic field sufficiently, the magnetic field generated at the lower comapri coil is canceled in the upper deflection, and the upper comafree coil is generated in the lower deflection. The upper comapri coil and lower to cancel the magnetic field Configuring a pair of mutually drum core and the compensation coil are connected respectively in series to the coma-free coils in parallel, and the magnetized surface is facing the respective drum cores was equipped with a magnetic material between each drum core. This is available for all deflection yokes, and is particularly useful for deflection yokes in which misconvergence is generated in which red and blue beams are scanned alternately on the left and right sides of the screen.
