Description

편향요크의 컨버전스 개선방법{METHOD FOR IMPROVING CONVERGENCE OF DEFLECTION YOKE}METHOD FOR IMPROVING CONVERGENCE OF DEFLECTION YOKE}

본 발명은 편향요크의 컨버전스 개선방법에 관한 것으로, 더욱 상세하게는 편향요크에 대한 HCR 특성의 차이를 나타내는 D-HCR 특성을 개선하여 G빔을 조정함으로써 컨버전스의 유효 폭을 키울 수 있도록 한 편향요크의 컨버전스 개선방법에 관한 것이다.The present invention relates to a method for improving the convergence of the deflection yoke, and more particularly, to improve the effective width of the convergence yoke by adjusting the G beam by improving the D-HCR characteristic representing the difference in the HCR characteristics with respect to the deflection yoke. To improve convergence.

일반적으로 편향요크는 음극선관의 외주에 장착되어 음극선관의 전자총으로부터 발사되는 전자빔을 편향시켜 정확도 있는 화상을 구현되게 하는 것으로, 코일스페이서의 내외주연에 수평편향코일 및 수직편향코일이 장착되는 구성으로 이루어진다.In general, the deflection yoke is mounted on the outer circumference of the cathode ray tube to deflect the electron beam emitted from the electron gun of the cathode ray tube to realize an accurate image. The deflection yoke is configured to mount a horizontal deflection coil and a vertical deflection coil on the inner and outer circumferences of the coil spacer. Is done.

편향요크를 구성하는 상기 수평 및 수직의 편향코일은 톱니파 펄스의 인가에 의해 보정 자계를 형성하여 스크린 주변부에서 전자빔 R(Red), G(Green), B(Blue)의 집중을 보상하는 컨버전스 기능을 수행하게 되며, 이러한 수평 및 수직의 편향코일에 의한 스크린 주변부의 보정이 미흡할 경우 전자빔이 스크린 상의 각 화소에 정확하게 주사되지 못하는 미스컨버전스 상태를 나타낸다.The horizontal and vertical deflection coils constituting the deflection yoke form a correction magnetic field by applying a sawtooth pulse to provide a convergence function for compensating the concentration of electron beams R (Red), G (Green), and B (Blue) at the periphery of the screen. If the correction of the periphery of the screen due to the horizontal and vertical deflection coils is insufficient, this indicates a misconvergence state in which the electron beam is not accurately scanned to each pixel on the screen.

특히 수평편향코일에 의한 보정이 미흡한 경우에는 화면의 좌우측 코너부와 중간부에 수평센터 라스터(HCR) 특성이 발생하게 된다. 여기서 HCR 특성은 R빔과 B빔은 스크린에 정확하게 주사되는 반면에 G빔은 스크린의 각 화소에 정확하게 주사되지 못하고 수평방향으로 오차가 발생하는 미스컨버전스이다.In particular, when the correction by the horizontal deflection coil is insufficient, horizontal center raster (HCR) characteristics are generated in the left and right corners and the middle of the screen. Here, the HCR characteristic is a misconvergence in which the R beam and the B beam are accurately scanned on the screen, while the G beam is not accurately scanned on each pixel of the screen and an error occurs in the horizontal direction.

이러한 수평센터 라스터 특성은 수평자계의 보정에 의해 컨버전스의 개선을 이루게 되며 컨버전스 측정장치를 통한 화면 상태의 측정치를 파악함으로써 확인할 수 있게 된다.The horizontal center raster characteristic is improved by the correction of the horizontal magnetic field and can be confirmed by grasping the measurement value of the screen state through the convergence measuring device.

그런데, 종래에는 코너부 HCR 특성과 중간부 HCR 특성에 대한 차이를 나타내는 D-HCR 특성에 대한 개선이 어려운 구성을 이루므로 인하여 편향요크의 컨버전스가 좋지 않은 문제점이 있었다.However, in the related art, the convergence of the deflection yoke is not good due to the difficult configuration of the D-HCR characteristic, which indicates the difference between the corner portion HCR characteristic and the middle portion HCR characteristic.

본 발명은 상기와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적으로 하는 바는 편향요크의 내주연에 장착되는 수평편향코일의 네크 핀부에 대한 턴 수를 조정함으로써 D-HCR 특성을 개선하여 컨버전스의 유효 폭을 키울 수 있도록 한 편향요크의 컨버전스 개선방법을 제공하는데 있다.The present invention has been proposed to solve the above problems, and its object is to improve the convergence by improving the D-HCR characteristics by adjusting the number of turns for the neck pin portion of the horizontal deflection coil mounted on the inner circumference of the deflection yoke. The present invention provides a method for improving the convergence of a deflection yoke to increase the effective width of the deflection yoke.

상기와 같은 목적을 달성하기 위한 본 발명은 네크 핀부 및 스크린 핀부를 형성한 수평편향코일에 펄스인가에 의한 보정 자계를 형성하여 편향요크의 컨버전스를 개선하도록 한 방법에 있어서,In the present invention for achieving the above object in the method to improve the convergence of the deflection yoke by forming a correction magnetic field by applying a pulse to the horizontal deflection coil formed the neck pin portion and the screen pin portion,

상기 수평편향코일의 네크 핀부에 턴(turn) 수를 줄이거나 넣지 않도록 하여 편향요크의 네크부측으로 작용하는 보정 자계의 크기를 작게 하는 것을 그 기술적 특징으로 한다.The technical feature is to reduce the size of the correction magnetic field acting on the neck portion side of the deflection yoke so that the number of turns is not reduced or inserted into the neck pin portion of the horizontal deflection coil.

이하, 본 발명에 따른 바람직한 실시예를 도면을 참조하면서 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the drawings.

도 1은 편향요크에 장착되는 수평편향코일을 나타낸 측면도이다.1 is a side view showing a horizontal deflection coil mounted on a deflection yoke.

도 1에 나타낸 바와 같이, 수평편향코일(10)은 편향요크의 네크부 측에 장착되는 네크 핀부(11)와 편향요크의 스크린부 측에 장착되는 스크린 핀부(12)로 이루어지며 편향요크의 내주연에 밀착 결합된다.As shown in Fig. 1, the horizontal deflection coil 10 is composed of a neck pin portion 11 mounted on the neck portion side of the deflection yoke and a screen pin portion 12 mounted on the screen portion side of the deflection yoke. Closely coupled to the leading edge.

본 발명에 따른 편향요크의 컨버전스 개선방법은 상기와 같은 구성으로 이루어진 수평편향코일(10)의 네크 핀부(11)의 턴(turn) 수를 조정하여 HCR 특성의 코너부와 중간부 차이를 나타내는 D-HCR 특성을 개선하기 위한 것으로, 상기 네크 핀부(11)에 턴 수를 넣지 않거나 턴 수를 줄이면 D-HCR 특성을 좋게 할 수 있다.In the method of improving the convergence of the deflection yoke according to the present invention, the number of turns of the neck pin portion 11 of the horizontal deflection coil 10 having the above configuration is adjusted to indicate a difference between the corner portion and the middle portion of the HCR characteristic. In order to improve the -HCR characteristic, if the number of turns is not put in the neck pin portion 11 or the number of turns is reduced, the D-HCR characteristic can be improved.

즉, 수평편향코일(10)의 네크 핀부(11)에 턴 수를 줄이거나 넣지 않으면 편향요크의 네크부 측으로 작용되는 수평편향코일(10)의 보정 자계의 크기가 작아지게 된다.That is, if the number of turns is not reduced or inserted into the neck pin portion 11 of the horizontal deflection coil 10, the magnitude of the correction magnetic field of the horizontal deflection coil 10 acting on the neck portion side of the deflection yoke becomes small.

이는 전자총에서 발사되는 G빔을 조정하여 크게되지 않도록 하므로 스크린의 각 화소에 정확하게 주사되도록 한다.This adjusts the G-beams emitted by the electron gun so that they do not become large, so they are accurately scanned on each pixel of the screen.

따라서, D-HCR 특성을 용이하게 개선시킬 수 있으며 컨버전스의 동특성에 대한 유효 폭을 키울 수 있다.Therefore, the D-HCR characteristic can be easily improved and the effective width for the dynamic characteristic of convergence can be increased.

이상에서 살펴본 바와 같이 본 발명에 따른 편향요크의 컨버전스 개선방법에의하면, 수평편향코일의 네크 핀부에 턴 수를 넣지 않거나 줄이면 수평편향코일의 네크부 측에 작용하는 보정 자계 크기가 작아지면서 G빔이 크게되지 않아 D-HCR 특성을 용이하게 개선할 수 있게 되며, 이를 통해 컨버전스의 유효 폭이 커지는 유용함이 있게 된다.As described above, according to the method of improving the convergence of the deflection yoke according to the present invention, when the number of turns is not put or reduced in the neck pin portion of the horizontal deflection coil, the G-beam becomes smaller while the magnitude of the correction magnetic field acting on the neck portion of the horizontal deflection coil is reduced. Since it is not large, it is possible to easily improve the D-HCR characteristic, and this makes it useful to increase the effective width of convergence.
