Abstract
Description
본 발명은 컬러음극선관의 편향요크(DR)의 VCR보정장치에 관한 것으로, 보다 상세하게는 컬러음극선관의 상측과 하측에 주사되는 VCR량의 불균일을 보정할 수 있도록 한 편향요크의 VCR보정장치에 관한 것이다.The present invention relates to a V CR correction device for deflection yoke (DR) of a color cathode ray tube, and more particularly, to a V yoke of a deflection yoke for correcting an unevenness of the amount of V CR injected into an upper side and a lower side of a color cathode ray tube. It relates to a CR correction device.
일반적으로, 컬러음극선관의 전자총에서 방출되는 그린(G)빔과 레드(R)빔 및 블루(B)빔은 컬러음극선관의 상하에 주사될 때 불균일(Unbalance)이 있는데, 이는 편향요크(DY)의 컨버젼스 보정회로를 적용하여 수정하게 된다.In general, the green (G) beam, the red (R) beam, and the blue (B) beam emitted from the electron gun of the color cathode ray tube have unbalance when scanned above and below the color cathode ray tube, which is a deflection yoke (DY). Is applied by applying the convergence correction circuit.
제1도는 종래의 편향요크의 VCR보정을 나타낸 회로도이고, 제2도는 편향요크의 6극 코일을 적용하여 전자빔의 편향을 나타내 도면으로서, 편향요크 6극 코일회로(1)을 적용하여 전자총의 그린(G)빔의 조정하여 컬러음극선관의 상·하 그린감도를 조정하게 된다.FIG. 1 is a circuit diagram showing a conventional V CR correction of a deflection yoke. FIG. 2 is a view showing deflection of an electron beam by applying a six-pole coil of a deflection yoke. By adjusting the green (G) beam, the upper and lower green sensitivity of the color cathode ray tube is adjusted.
그런데 이러한 6극 코일회로(1)의 적용에 의한 종래 컬러음극선관의 편향요크의 VCR보정장치는 상·하 동일량으로 VCR을 보정함으로써 처음부터 편항요크(DY)의 VCR불균일이 있는 경우에는 6극 코일을 추가함으로 제2도의 도시와 같이 상하 동일한 량으로 보정되므로 VCR특성이 더욱 악화되는 문제점이 초래되게 된다.However, the conventional color cathode ray tube the deflection yoke V CR correcting apparatus according to the application of this 6-pole coil circuit 1 with a V CR unevenness of the upper and lower pyeonhang yoke (DY) in the first place by correcting the V CR to the same amount of In this case, since the six-pole coil is corrected by the same amount as shown in FIG. 2, the V CR characteristic is further deteriorated.
더욱이 편향요크의 양산권형이 조금씩 특성이 악화될 경우, 고가의 권형을 불량처리함으로써 편향요크의 제조원가의 상승이 초래되어 컬러음극선관의 생산단가가 상승되게 된다.In addition, when the mass production winding of the deflection yoke is deteriorated little by little, the expensive winding is poorly processed, resulting in an increase in the manufacturing cost of the deflection yoke, thereby increasing the production cost of the color cathode ray tube.
본 발명은 이러한 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 편향요크의 VCR내로우는 물론 VCR불균일까지 선택적으로 보정할 수 있도록 한 편향요크의 VCR보정장치를 제공함에 있다.The present invention provides these as one made in view of prior art to solve the various problems of the art, object of the present invention is crying well as a deflection yoke of the V CR correction to selectively correcting up to V CR irregularity into the deflection yoke V CR device Is in.
상기한 목적을 실현하기 위한 본 발명에 따른 편향요크의 VCR보정장치의 특징은, 편향요크의 수직코일에 설치되어 6극코일이 상기 수직코일에 직렬연결되어 있는 편향요크의 VCR보정장치에 있어서, 저항(R)과 다이오드(D)가 직렬연결되며 상기 6극코일과 병렬접속된 것으로 구성된다.Features of the deflection yoke of the V CR correction device according to the invention for realizing the above object, is installed in the vertical coil of the deflection yoke to the V CR compensator of the deflection yoke, which is a six-pole coil serially connected to the vertical coil The resistor R and the diode D are connected in series and are connected in parallel with the six-pole coil.

이하, 본 발명에 따른 편향요크의 VCR보정장치의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the V CR correction device of the deflection yoke according to the present invention will be described.
제3도는 본 발명에 따른 편향요크의 VCR보정을 나타낸 회로도로서, 도면에 도시된 바와 같이 편향요크에 6극 코일회로(1)를 적용한 기존의 6극 코일회로(1)에 저항 (R)과 다이오드(D)를 직렬로 연결한 것이다.3 is a circuit diagram illustrating V CR correction of a deflection yoke according to the present invention, and as shown in the drawing, a resistance R of a conventional 6 pole coil circuit 1 to which a 6 pole coil circuit 1 is applied to a deflection yoke. And diode (D) are connected in series.
즉, 기존의 6극 코일회로(1)에 저항(R)과 다이오드(D)로 구성된 보정회로(2)를 병렬로 연결시킨 것이다.That is, the conventional six-pole coil circuit (1) is connected in parallel with the correction circuit (2) consisting of a resistor (R) and a diode (D).
그리고, 편향요크에 흐르는 전류의 방향을 바꾸어서 선택적으로 VCR내로우 또는 VCR불균일을 보정하도록 한 것이다.And, optionally, to one to compensate for the narrow or non-uniform V V CR CR changing the direction of the current flowing in the deflection yoke.
이와 같이 본 발명의 편향요크의 VCR보정장치는 예를 들면, 도면 좌측에서 우측으로 전류가 흐를 경우에는 6극 코일회로(1)보다 저항이 작은 다이오드(D)측(아래쪽의 보정회로)으로 전류가 흐르게 된다.As described above, the V CR correction device of the deflection yoke of the present invention is directed to the diode D side (lower correction circuit) having a lower resistance than the six-pole coil circuit 1 when a current flows from the left side to the right side of the drawing. Current will flow.
따라서, 6극 코일회로(1)는 동작하지 않게 된다.Therefore, the six-pole coil circuit 1 does not operate.
반대로 전류의 흐름을 좌측으로 흐르게 할 경우에는 다이오드(D)에 의해 다이오드(D)측(아래쪽)으로는 전류가 흐르지 않게되므로 6극 코일회로(1)쪽으로만 전류가 흐르게 된다.On the contrary, when the current flows to the left side, the current does not flow to the diode D side (bottom) by the diode D, so that the current flows only to the six-pole coil circuit 1.
따라서, 편향요크의 VCR에 따라 전류의 방향을 선택하여 6극 코일회로(1)에 병렬연결된 저항(R) 및 다이오드(D)측 회로를 동작시켜 편향요크의 하측 VCR불균일을 선택적으로 보정할 수 있게 되는 것이다.Therefore, by selecting the direction of the current according to the V CR of the deflection yoke, the resistance (R) and diode (D) side circuits connected in parallel to the 6-pole coil circuit (1) are operated to selectively correct the lower V CR unevenness of the deflection yoke. You can do it.
이상에서 상세히 설명한 바와 같이 본 발명의 편향요크 VCR보정장치는 기존의 6극 코일회로에 저항과 다이오드를 병렬 연결함으로써 전류방향을 선택하여 상측 또는 하측의 VCR을 선택적으로 보정하여 편향요크의 VCR불균일에 의한 사용 불가능한 제품을 본 발명의 방법으로 수리하여 사용할 수 있으므로 생산성 증가는 물론 고품위의 컬러음극선관을 제조할 수 있는 특장점이 있는 것이다.As described in detail above, the deflection yoke V CR compensator of the present invention selects a current direction by connecting a resistor and a diode in parallel to an existing six-pole coil circuit to selectively correct the V CR of the upper or lower side to selectively correct the V of the deflection yoke. Since the product which cannot be used due to CR non-uniformity can be repaired and used by the method of the present invention, there is an advantage of increasing productivity as well as manufacturing a high-quality color cathode ray tube.
