Abstract
이 발명은 편향요크의 그린 빔 드롭현상 방지장치에 관한 것으로서, 코일세퍼레이터의 네크부 상면에 전자총이 장착되는 삽입부를 중심으로 대응되도록 설치되어 수평 및 수직편향코일이 자계에 의해 발생되는 VCR 미스컨버젼을 보정하는 코마프리 보정편 좌,우 양측으로 자성을 띄는 자성부재인 제1,2보조편을 장착하고, 이 제1,2보조편에 G빔의 자계량을 증가시키는 제1,2보조코일을 추가적으로 권선시켜 수평 및 수직편향코일의 자계에 의해 발생되는 VCR 미스컨버젼스형상을 보정함과 동시에 G빔이 화면의 중앙부보다 양측부에서 상대적으로 급격하게 작아지는 그린 빔 드롭현상을 방지하여 화면의 특성 산포를 최소화시킬 수 있다.The present invention relates to a green beam drop prevention device of a deflection yoke, and is installed to correspond to an insertion part on which an electron gun is mounted on an upper surface of a neck portion of a coil separator so that horizontal and vertical deflection coils are generated by a magnetic field. The first and second auxiliary pieces, which are magnetic members exhibiting magnetism, are mounted on both the left and right sides of the comapri correction piece to be corrected, and the first and second auxiliary coils for increasing the magnetic field of the G beam are mounted on the first and second auxiliary pieces. Additional windings compensate for the VCR misconvergence shape caused by the magnetic fields of the horizontal and vertical deflection coils, while preventing the green beam drop, which causes the G-beams to become relatively smaller on both sides than the center of the screen. Can be minimized.
