본 고안은 음극선관의 컨버젼스보정장치에 관한 것으로, 특히 녹색(G) 전자총 상하측에 보조코일을 설치하여 음극선관의 컨버젼스를 개선시키도록 한 음극선관의 컨버젼스보정장치에 관한 것이다.The present invention relates to a convergence correcting device for a cathode ray tube, and more particularly to a convergence correcting device for a cathode ray tube to improve the convergence of a cathode ray tube by installing auxiliary coils above and below a green (G) electron gun.
컬러브라운관에서는 RㆍGㆍB 전자총으로부터 적(R)ㆍ녹(G)ㆍ청(B)의 3색 비임이 방사되어 그 전자비임이 스크린의 전반에 형성된 RㆍGㆍB 형광체에 정확하게 위치시키는 컨버젼스가 행해져야만 한다.In a color CRT, three colors of red (R), green (G) and blue (B) beams are emitted from the R, G, and B electron guns, and the electron beams are accurately positioned on the R, G, and B phosphors formed in the first half of the screen. Convergence must be done.
즉, 제1도에 도시된 바와 같이 전자총(RㆍGㆍB)으로부터 발생된 3색 단자비임에 대한 컨버젼스가 실행되지 않는 경우에는 RㆍGㆍB컬러(R1ㆍG1ㆍB1)가 다색 화상으로 스크린상에 형성되어 화질의 열화가 초래된다. 이때문에 종래에는 제2도에 도시된 바와 같이 3색 전자비임의 편향을 담당하는 편향요크(10)에 전자비임편향을 위해 전계(20)를 발생하도록 코일(30)이 권취된다. 따라서, 이러한 구성에 의해 전자비임의 이동방향을 조정하여 컨버젼스가 실현된다.That is, as shown in FIG. 1, when the convergence of the three-color terminal beams generated from the electron guns R, G, B is not performed, the R, G, B colors (R1, G1, B1) are multicolor images. Is formed on the screen, resulting in deterioration of image quality. For this reason, conventionally, as shown in FIG. 2, the coil 30 is wound so as to generate the electric field 20 for the electron beam deflection in the deflection yoke 10 which is responsible for the deflection of the three-color electron beam. Therefore, by such a configuration, the convergence is realized by adjusting the moving direction of the electron beam.
그런, 3색 전자비임중 녹색비임은 편향요크주변의 적색 및 청색 전자비임에 비해 편향요크(10)로부터 비교적 원거리에 위치되므로 상대적인 편향감도가 열화된다. 이때문에, 종래에는 편향요크세퍼레레이터의 후방(즉, 브라운관의 네크측)에 보조코일을 설치하여 녹색전자비임에 대한 자계영향력을 강화시키는 방안이 강구되어 있기는 하지만, 그 보정코일에 의한 자계가 R과 B의 전자비임에도 작용하게 되므로 녹색비임에 대한 충분한 자계력 보정효과를 얻지 못한다는 단점이 있다.Such a green beam of the three-color electron beam is located relatively far from the deflection yoke 10 relative to the red and blue electron beams around the deflection yoke, so that the relative deflection sensitivity is degraded. For this reason, conventionally, a method of strengthening the magnetic field influence on the green electron beam by providing an auxiliary coil in the rear of the deflection yoke separator (that is, the neck side of the CRT) has been devised. Since the magnetic field acts on the electron beams of R and B, there is a disadvantage in that sufficient magnetic force correction effect is not obtained for the green beam.
따라서, 본 발명은 편향요크에 권취되는 수직코일의 일단이 권취된 보조코일을 설치하여 녹색전자비임의 자계력을 보정함으로써 컨버젼스를 향상시키도록 된 음극선관의 컨버젼스보정장치를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a cathode ray tube convergence correcting device to improve convergence by correcting a magnetic field force of a green electron beam by installing an auxiliary coil wound around one end of a vertical coil wound on a deflection yoke. .
상기한 목적을 달성하기 위해, 본 고안에 따르면 3색전자비임(RㆍGㆍB)을 편향시키기 위해 편향요크 세퍼레이(10-1, 10-2)에 권취된 수직코일(30-1, 30-2)을 갖춘 편향요크에 있어서, 상기 수직 코일(30-1, 30-2)의 각 일측권선이 권취되어 녹색전자비임에 따라 전계를 발생하는 보조코일(40-1, 40-2)이 녹색전자총(G)의 상하측에 설치된 것을 특징으로 한다.In order to achieve the above object, according to the present invention, the vertical coils 30-1, wound on the deflection yoke separators 10-1 and 10-2, to deflect the three-color electron beams (R, G, B). 30-2), the auxiliary coils 40-1 and 40-2 for winding one side of each of the vertical coils 30-1 and 30-2 to generate an electric field in accordance with the green electron beam. It is characterized by being installed above and below this green electron gun G.
상기한 구성에 따르면, 수직코일의 일측을 녹색전자비임에 대한 자계보정을 위한 보조코일로 사용하여 음극선관의 컨버젼스를 향상시킬 수 있다.According to the above configuration, it is possible to improve the convergence of the cathode ray tube by using one side of the vertical coil as an auxiliary coil for magnetic field correction for the green electron beam.
이하, 본 고안에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 음극선관의 컨버젼스보정장치를 나타낸 도면으로, RㆍGㆍB전자비임을 편향시키기 위해 편향요크의 세퍼레이터(10-1, 10-2)에는 수직코일(30-1, 30-2)이 권취된다. 이 수직 코일(30-1, 30-2)에 의해 발생되는 자계(20)에 의해 RㆍGㆍB전자비임이 편향되어 도시되지 않은 스크린에 도포된 형광체상에 정확하게 도달된다.3 is a view showing a convergence correction device for a cathode ray tube according to the present invention, in order to deflect the R, G, and B electron beams, to the separators 10-1 and 10-2 of the deflection yoke. 30-2) is wound up. The magnetic field 20 generated by the vertical coils 30-1 and 30-2 deflects the R, G, and B electron beams and accurately reaches the phosphor coated on the screen (not shown).
이 경우, 녹색전자비임이 적색과 청색의 전자비임에 비해 상대적으로 약한 자계를 받게 되지만, 본 발명에 따르면 수직코일(30-1, 30-2)을 그 녹색전자총(G)의 상하측에 설치된 침형상의 보조코일(40-1, 40-2)로서 사용하여 녹색전자비임 보정용 자계(50)를 발생하게 된다. 따라서, 녹색전자비임에 보다 강화된 자계(50)가 가해지므로 음극선관의 컨버젼스보정에 충분한 효과를 얻을 수 있다.In this case, the green electron beam receives a relatively weak magnetic field compared to the red and blue electron beams, but according to the present invention, the vertical coils 30-1 and 30-2 are installed above and below the green electron gun G. By using the needle-shaped auxiliary coils 40-1 and 40-2, the green electron beam correction magnetic field 50 is generated. Therefore, since a stronger magnetic field 50 is applied to the green electron beam, a sufficient effect can be obtained for the convergence correction of the cathode ray tube.
한편, 본 발명은 상기한 실시예로 한정되지 않고, 발명의 요지를 벗어나지 않는 범위에서 여러가지로 변형 및 변경하여 실시할 수 있다.In addition, this invention is not limited to the above-mentioned Example, It can variously deform and change in the range which does not deviate from the summary of invention, and can be implemented.
