슬릿보빈형 편향요크의 상하왜곡 보정장치{DISTORTION CORRECTION DEVICE OF SLIT-BOBBIN-TYPE DEFLECTION YOKE}Vertical distortion correction device for slit bobbin type deflection yoke {DISTORTION CORRECTION DEVICE OF SLIT-BOBBIN-TYPE DEFLECTION YOKE}

본 발명은 슬릿보빈형 편향요크의 상하왜곡 보정장치에 관한 것으로서, 보다 상세하게는 슬릿보빈형 편향요크에 자계보정용 보조코일의 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 be installed in the slit bobbin type deflection yoke so as to be located at the center of the horizontal coil of the auxiliary coil for magnetic field correction to correct the miss convergence of the electron beam. I would have to.

일반적으로 편향요크는 음극선관의 넥크부위에 설치되어 전자총에서 발사되는 전자빔의 진행방향을 좌우로 움직여주는 수평편향코일과, 상하로 움직여주는 수직편향코일을 자심코어에 조합하여 이루어지며 이때의 수평코일의 한 예를 제1도에 도시하였다.Generally, the deflection yoke is installed on the neck of the cathode ray tube and is made by combining the horizontal deflection coil which moves the direction of the electron beam emitted from the electron gun to the left and right and the vertical deflection coil which moves up and down to the core core. An example of this is shown in FIG.

상기의 종래 수평코일은 편향요크의 좌우로 수평코일을 권선함으로써 셀프 컨버젼스에 의해 미스 컨버젼스를 보정하였으나, 이러한 종래의 코일 권선 방식에 의하면 제 2도의 (가)와 같이 화면(1)의 상 하부에 화면의 중앙부와 주변부에서 수평 편향력의 크기가 다름에 의한 핀 형상의 왜곡이 발생하게 되었다.The conventional horizontal coil corrects miss convergence by self-convergence by winding horizontal coils to the left and right of the deflection yoke. However, according to the conventional coil winding method, as shown in FIG. Pin-shaped distortion occurs due to the difference in the horizontal deflection force in the center and periphery of the screen.

따라서 종래의 슬릿보빈형 편향요크에는 수평코일의 상하에 상부마그네트와 하부마그네트를 설치함으로써, 수평코일의 주변에 자계를 발생시켜 미스 컨버젼스를 보정하여 화면의 상하부에 핀 형상으로 왜곡되는 것을 방지하고 있다.Therefore, in the conventional slit bobbin-type deflection yoke, the upper magnet and the lower magnet are provided above and below the horizontal coil, thereby generating a magnetic field around the horizontal coil, thereby correcting the miss convergence and preventing the pin shape from being distorted in the upper and lower portions of the screen. .

그러나, 이러한 종래의 보정방법은 수평코일의 상부와 하부에 마그네트를 설치하기 때문에 편향요크의 가격이 상승되었을 뿐만 아니라, 그 마그네트에 의해 발생되는 부수적인 자계가 산포되어 또 다른 문제점을 야기시켰다.However, this conventional correction method not only increases the price of the deflection yoke because magnets are installed on the upper and lower portions of the horizontal coil, but also causes an additional problem due to the scattering of an additional magnetic field generated by the magnet.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 본 발명의 목적은 수평코일에 제2의 수평코일을 추가 설치하여 보정 자계를 발생시킴으로써 화면의 중앙으로부터 주변으로 갈수록 수직분력이 증가되는 보상력을 전자빔에 작용시켜, 화면 상 하부의 핀형상 왜곡을 보정할 수 있는 슬릿보빈형 편향요크의 상하왜곡 보정장치를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to install a second horizontal coil in the horizontal coil to generate a correction magnetic field to compensate the vertical component increases from the center of the screen toward the periphery The present invention provides a device for correcting vertical distortion of a slit bobbin-type deflection yoke capable of correcting pin-shaped distortion on a lower portion of an image by applying a force to an electron beam.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 슬릿보빈형 편향요크의 상하왜곡 보정장치의 특징은, 제 1수평코일의 권선 방향과 반대 방향으로 역권선한 제 2수평코일을 상기 제 1수평코일의 중앙부에 위치하도록 설치하고, 상기 제 2수평코일에 역권선되는 권선량을 조절하여 화면 중앙으로부터 주변으로 갈수록 수직 분력이 조절(증가)되는 보상력을 발생시키도록 함에 있다.Features of the vertical distortion correction device of the slit bobbin-type deflection yoke according to the present invention for achieving the above object, the first horizontal coil to the second horizontal coil winding in the opposite direction to the winding direction of the first horizontal coil It is installed so as to be located at the center of the, and to adjust the amount of winding wound on the second horizontal coil to generate a compensation force that is adjusted (increased) the vertical component from the center of the screen toward the periphery.

이하, 본 발명에 따른 슬릿보빈형 편향요크의 상하왜곡 보정장치의 바람직한 실시예에 대하여 첨부도면을 참고하여 상세히 설명한다.Hereinafter, a preferred embodiment of the vertical distortion correction device of the slit bobbin-type deflection yoke according to the present invention will be described in detail with reference to the accompanying drawings.

제 4도는 본 발명에 의한 수평코일을 나타낸 것으로서 (가)에서와 같이 제 1 수평코일(10)의 권선 방향(편향전류가 지면으로 들어가는 방향은 원안의 엑스(X)로표시하고, 편향전류가 지면으로부터 나오는 방향은 원안의 점(·)으로 표시함)과, 반대 방향으로 역권선한 제 2수평코일(20)을 상기 제 1수평코일(10)의 중앙부에 위치하도록 설치한다.4 is a horizontal coil according to the present invention, as shown in (A), the winding direction of the first horizontal coil 10 (the direction in which the deflection current enters the ground is indicated by X (X) in the circle, and the deflection current is The direction coming out from the ground is indicated by a dot (·) in the circle, and the second horizontal coil 20 reversely wound in the opposite direction is provided so as to be located at the center of the first horizontal coil 10.

그리고 상기 제 2수평코일(20)은 역권선되는 권선량을 조절하여 편향전류를 흘려줌에 따라 화면 중앙으로부터 주변으로 갈수록 수직분력이 조절되는 보상력(F)을 발생시키도록 권선한다.In addition, the second horizontal coil 20 is wound to generate a compensation force (F) in which the vertical component is adjusted toward the periphery from the center of the screen as the deflection current flows by adjusting the winding amount reversely wound.

제 5도는 본 발명의 제 2수평코일에서 발생한 보상력을 설명하기 위한 참고도로서 도면에 도시된 바와 같이, 보상력(F)은 제 2수평코일(20)에 역권선되는 권선량을 조절함에 따라 화면 중앙으로부터 주변으로 갈수록 수직분력(Fx)과 수평분력(Fy)이 변화되는 것으로서, 제 2수평코일의 역권선수를 조정하여 핀 왜곡의 보정량이 다르게 될 수 있음을 보이고 있다.5 is a reference diagram for explaining the compensation force generated in the second horizontal coil of the present invention, as shown in the drawing, the compensation force (F) is used to adjust the amount of winding reversely wound on the second horizontal coil (20) Accordingly, as the vertical component Fx and the horizontal component Fy change from the center of the screen to the periphery, it is shown that the amount of correction of the pin distortion may be changed by adjusting the reverse power of the second horizontal coil.

제 6도는 본 발명에 의한 제 2수평코일의 역권선수를 변화시키면서 측정한 핀수의 실험결과를 나타낸 참고표로서 도시된 바와 같이, (가)는 중앙부의 역권선수가 없을 때의 경우로서 상하왜곡이 5.86%이며, (나)는 중앙부의 역권선수가 7회일때의 경우로서 상하왜곡이 3.93%이며, (다)는 중앙부의 역권선수가 9회일때의 경우로서 상하왜곡이 3.7%로 나타남을 보이고 있다.6 is a reference table showing the experimental results of the number of pins measured while changing the stationary winding of the second horizontal coil according to the present invention. 5.86%, (b) is the case of seven centers of gravity, and the up and down distortion is 3.93%, and (c) is the case of nine times of center, and the top and bottom distortions are 3.7%. have.

이상에서와 같은 구성을 참고하여 본 발명에 따른 슬릿보빈형 편향요크의 상하왜곡 보정장치의 동작을 설명하면 다음과 같다.Referring to the configuration as described above will be described the operation of the vertical distortion correction device of the slit bobbin-type deflection yoke according to the present invention.

본 발명에 의한 제 2수평코일(20)의 권선 방향은 제 1수평코일(10)의 권선방향에 반대방향으로 역권선하여 상기 제 1수평코일(10)의 중앙부에 위치하도록 설치하게 되면 제 1수평코일(10)과 제 2수평코일(20)에서는 제 4도의 (나)와 같은 자계가 발생한다.When the winding direction of the second horizontal coil 20 according to the present invention is reversely wound in a direction opposite to the winding direction of the first horizontal coil 10, the winding direction of the second horizontal coil 20 is located at the center of the first horizontal coil 10. In the horizontal coil 10 and the second horizontal coil 20, a magnetic field as shown in (b) of FIG. 4 is generated.

이때 상기의 자계는 제 1수평코일(10)과는 다른 추가자계가 발생하게 되는데, 이것을 상세하게 설명하면 제 5도와 같이 좌측 편향의 경우를 예로 들면, 이 추가자계는 수평방향으로 영향을 미치는 수평분력(Fx)과 수직방향으로 영향을 비치는 수직분력(Fy)으로 표시할 수 있으며, 여기서 화면 상하의 핀 형상의 왜곡을 보정하는 성분은 수직분력(Fy)인데, 이 수직분력은 화면의 주변으로 갈수록 수평 편향전류가 커지기 때문에 이 수직방향 성분의 힘도 커지게 된다.In this case, an additional magnetic field different from that of the first horizontal coil 10 is generated. In detail, the additional magnetic field has a horizontal influence in the horizontal direction. It can be expressed as the vertical component (Fy) that affects the component component (Fx) in the vertical direction. The component that corrects the distortion of the pin shape at the top and bottom of the screen is the vertical component (Fy). Since the horizontal deflection current increases, the force of this vertical component also increases.

따라서 화면의 주변으로 갈수록 커지는 보상력(F)의 작용으로 화면의 상하에 발생되는 핀 형상의 왜곡을 보정할 수 있게 된다.Therefore, the distortion of the pin shape generated on the upper and lower sides of the screen can be corrected by the action of the compensating force F that increases toward the periphery of the screen.

이상에서와 같이 본 발명에 따른 슬릿보빈형 편향요크의 상하왜곡 보정장치에 의하면 수평코일에 왜곡보정용 마그네트가 없이도 상하부의 핀 왜곡을 보정할 수 있을 뿐만 아니라, 상기 마그네트를 대신하여 왜곡을 보정하기 때문에 마그네트가 가지는 자계의 산포를 줄일 수 있고 또한, 편향요크의 가격을 낮추며 따라서 편향요크의 설계자유도를 향상시킬 수 있는 유용함이 있다.As described above, according to the vertical distortion correction apparatus of the slit bobbin-type deflection yoke according to the present invention, not only the distortion of the upper and lower pins can be corrected without the distortion correction magnet in the horizontal coil, but also the distortion is corrected in place of the magnet. It is useful to reduce the dispersion of the magnetic field of the magnet and to lower the price of the deflection yoke and thus to improve the design freedom of the deflection yoke.
