이 고안은 고해상도의 모니터에 관한 것으로서, 고해상도의 모니터에서 발생되는 미스콘버젼스를 보정하기 위하여 장착되는 수직 보정코일의 자계 방향과 수직 편향코일의 누설자계의 자계방향을 동일하게 형성하여 수평 편향코일의 보정량을 증가시키기 위한 미스콘버젼스 보정장치에 관한 것이다.The present invention relates to a high resolution monitor. A horizontal deflection coil is formed by forming the magnetic field direction of a vertical correction coil mounted in order to correct misconvergence generated in a high resolution monitor and the magnetic field direction of a leakage magnetic field of the vertical deflection coil. It relates to a misconvergence correction device for increasing the correction amount of.

일반적인 편향요크(10)는 대개 한쌍의 수평편향코일(도시생략)과 수직편향코일(V)로 구성되어 전자총에서 방사되는 빔을 수평 및 수직방향으로 편향시키는 자계를 만들게 된다.The general deflection yoke 10 is generally composed of a pair of horizontal deflection coils (not shown) and vertical deflection coils V to create magnetic fields for deflecting beams emitted from the electron gun in the horizontal and vertical directions.

그러나, 3전자총방식의 모니터에서 편향요크의 기구적인 오차 및 컬러수상관의 응용변경등에 의하여 3빔이 한군데 집중되지 못하는 미스콘버젼스 현상이 생기게 된다.However, due to the mechanical error of the deflection yoke and the application of the color receiver in the three electron gun type monitor, there is a misconvergence phenomenon in which the three beams are not concentrated in one place.

이와 같이 발생된 미스콘버젼스를 보정하기 위하여 종래에는 제2도 및 제3도에 나타낸 바와 같이 수직 편향코일(V)에 직렬로 연결된 수직 보정코일(C1)의 우측에는 제1수평 편향코일(H1)에 직렬로 연결된 제1수평 보정코일(C2), (C3)이 장착되고, 상기 수직 보정코일(C1)의 좌측에는 제2수평 편향코일(H2)에 직렬로 연결된 제2수평 보정코일(C4), (C5)이 장착되어 있었다.In order to correct the misconvergence generated as described above, a first horizontal deflection coil (1) is disposed on the right side of the vertical correction coil C1 connected in series to the vertical deflection coil V as shown in FIGS. 2 and 3. First horizontal correction coils C2 and C3 connected in series to H1) are mounted, and a second horizontal correction coil C2 connected in series to a second horizontal deflection coil H2 is disposed on the left side of the vertical correction coil C1. C4) and (C5) were attached.

그리고 상기 제1 및 제2수평 보정코일(C2~C5)의 인덕턴스를 증가시키는 보정용 마그네트(M1), (M2)가 장착되어 있으며, 미스콘버젼스 보정장치(20)는 제1도에 나타낸 바와 같이 보빈에 조립하여 터미널 보오드(30)에 장착하므로서 편향요크에 고정설치되어 있었다.The magnets M1 and M2 for increasing the inductance of the first and second horizontal correction coils C2 to C5 are mounted, and the misconvergence correction device 20 is shown in FIG. It was assembled to the bobbin and fixed to the deflection yoke while being mounted on the terminal board 30.

그러나, 상기 미스콘버젼스 보정장치는 제2도에 나타낸 바와 같이 수직 보정코일(C1)에 의하여 발생되는 자속(φV)의 방향과 수직 편향코일(V)에 의하여 발생되는 누설 자속(φVLEAK)의 방향이 반대로 형성되도록 조립되어 있어, 수직 보정코일(C1)의 자속(φV)과 수직 편향코일(V)의 누설 자속(φVLEAK)의 차만큼 그 보정량 감소되는 폐단이 있었으며, 제1 및 제2수평 보정코일(C2~C5)에 미치는 자속의 양이 작아지므로써, 제1 및 제2수평 보정코일(C2~C5)에 의한 보정량이 감소하여 화면의 구석부에는 R과 G의 색상이 벌어지는 미스콘버젼스 현상이 발생되는 문제점이 있었다.However, as shown in FIG. 2, the misconvergence correcting apparatus has a direction of the magnetic flux? V generated by the vertical correction coil C1 and the leakage magnetic flux? VLEAK generated by the vertical deflection coil V. As shown in FIG. It was assembled so as to be formed in the opposite direction, and there was a closed end whose correction amount was reduced by the difference between the magnetic flux φV of the vertical correction coil C1 and the leakage magnetic flux φVLEAK of the vertical deflection coil V, and the first and second horizontal Since the amount of magnetic flux on the correction coils C2 to C5 decreases, the amount of correction by the first and second horizontal correction coils C2 to C5 decreases, so that the colors of R and G spread in the corners of the screen. There was a problem that the version phenomenon occurs.

이 고안은 이와 같은 미스콘버젼스 현상을 제거하기 위한 것으로서, 이 고안의 목적은 수직 보정코일의 자속방향과 수직 편향코일의 누설 자속방향을 일치시킴으로써, 수평 보정코일의 보정량이 증가되어 화면의 구석에 나타나는 미스콘버젼스 현상을 제거시키기 위한 미스콘버젼스 보정장치를 제공하고자 함에 있다.This invention is to eliminate such misconvergence phenomenon. The purpose of this invention is to match the magnetic flux direction of the vertical correction coil with the leakage magnetic flux direction of the vertical deflection coil, so that the amount of correction of the horizontal correction coil is increased and the corner of the screen is increased.
