이 고안은 음극선관의 트릴 레마 가변장치에 관한 것으로서, 더욱 상세하개는 보빈에 보정코일이 권선된 자성편을 형성한후 편형요크의 전자총 삽입구 외측에 장착하여 R(Red)빔과 B(Blue)빔을 편향요크로 입사 하기 전에 빔간격을 조하므로써, 트릴 레마를 최적 조건으로 조정할 수 있도록 하는 음극선관의 트릴레마 가변장치에 관한 것이다.The present invention relates to a trillama variable device of a cathode ray tube, and more specifically, a magnetic piece wound with a correction coil is formed on a bobbin, and then mounted outside the electron gun insertion hole of the yoke of the yoke, and the R (Red) beam and B (Blue) The present invention relates to a trellis variable device of a cathode ray tube that adjusts a trellis to an optimum condition by adjusting a beam interval before the beam is incident on a deflection yoke.
일반적으로, TV수상기 또는 모니터 등의 음극선관에 사용되는 편향요크(1)는 제1도에 나타낸 바와 같이, 전자총 삽입구(3)가 형성된 네크부(2)와 스크린부로 이루어지는 코일세퍼레이터(4)의 내측에 수평편향코일(9)(9')(도시하지 않음)이 감겨지고, 외측으로는 수직편향코일(5)이 감겨진 페라이트코어(6)가 코어클램프(7)에 의해 조립되는 것으로, 상기 수평 및 수직편향코일(5)에 톱니파 펄스가 인가됨에 따라 자계를 형성하여 전자총에서 방사되는 R(적색), G(녹색), B(청색)의 전자빔을 주사시켜 화면상에 주사위치를 결정하게 된다.In general, the deflection yoke 1 used in a cathode ray tube such as a TV receiver or a monitor is formed as shown in FIG. 1 of the coil separator 4 having a neck portion 2 and a screen portion having an electron gun insertion opening 3 formed therein. The horizontal deflection coils 9 and 9 '(not shown) are wound on the inside, and the ferrite core 6 wound around the vertical deflection coils 5 is assembled by the core clamp 7, As the sawtooth pulse is applied to the horizontal and vertical deflection coils 5, a magnetic field is formed to scan dice on the screen by scanning R (red), G (green), and B (blue) electron beams emitted from the electron gun. Done.
그러나, 인라인(IN LINE)방식의 음극선관에 대응하여 콘버젼스 특성을 만족하기 위한 여러 가지 방법을 구사하여 왔으며 주로 수평편향코일의 구조적, 전기적 특성, 그리고 수직 편향코일의 위치, 크기 등을 변화시키는 것을 기본으로 하였으나, 최근들어 고정세화, 대형화, 플래트(FLAT)화 등의 추세에 따라 단순구조만으로 대응하기 어려우며 편향요크에 별도의 보정장치를 사용하여 편향요크 자체의 자속을 이용하는 방법으로 대응하였으나 부가되는 장치로 인한 부피가 증가될 뿐만 아니라 정밀한 트릴 레마를 조정하기에는 미흡하였던 것이다.However, various methods have been used to satisfy convergence characteristics in response to the in-line cathode ray tube, and mainly the structural and electrical characteristics of the horizontal deflection coil and the position and size of the vertical deflection coil are changed. However, in recent years, it is difficult to cope with simple structure according to the trend of high resolution, large size, and flattening, and by using a magnetic flux of the deflection yoke by using a separate correction device for the deflection yoke. Not only was the volume increased due to the added device, but it was also insufficient to adjust the precise trillama.
이 고안은 이러한 문제점을 해결하기 위한 것으로, 이 고안의 목적은 편향요크의 네크부에 형성된 전자총 삽입구의 일측인 보빈 상면에 보정코일이 권선된 보정편을 장착하여 전자총에서 방출되는 빔(R, B빔)이 화면으로 입사하기전에 상기 빔의 간격을 적정하게 조정함으로써 트릴 레마를 최적 조건으로 조정할 수 있도록 하는 음극선관의 트릴 레마 가변장치를 제공하는데 있다.This invention aims to solve this problem, and an object of this invention is to mount a correction coil wound around the upper surface of the bobbin, which is one side of the electron gun insertion hole formed in the neck portion of the deflection yoke, and the beam emitted from the electron gun (R, B). It is to provide a trillama variable device of the cathode ray tube to adjust the trillama to an optimum condition by adjusting the distance of the beam before the beam enters the screen.
이러한 목적을 달성하기 위한 이 고안에 따른 음극선관의 트릴 레마 가변장치의 특징은, 상기 ㄷ자형 보정부재(20)(20')에 원통형의 보빈(21)(21')을 삽입하고, 상기 보빈(21)(21')에 보정코일(22)(22')이 권선된 보정편(23)(23')을 형성하고 상기 보정편(23)(23')을 전자총 삽입구(3)에 서로 대향되게 설치하고, 상기 보정편(23)(23')을 수평편향코일(9)(9')에 연결된 정류회로(30)에 병렬로 접속되도록 한 점에 있다.A characteristic of the trillama variable device of the cathode ray tube according to the present invention for achieving this object is to insert the cylindrical bobbin 21, 21 'into the c-shaped correction member 20, 20', the bobbin (21) and (21 ') correction coils (23) and (23') are wound around the correction coils (22) and (22 '), and the correction pieces (23) and (23') are inserted into the electron gun insertion hole (3). It is provided so that the correction pieces 23 and 23 'may be connected in parallel to the rectifier circuit 30 connected to the horizontal deflection coils 9 and 9'.
이하, 이 고안에 따른 음극선관의 트릴 레마 가변장치의 일실시예에 대하여 첨부도면에 따라서 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of a trillama variable device of a cathode ray tube according to the present invention will be described in detail with reference to the accompanying drawings.
먼저, 제6도에 도시된 바와 같이 A방향으로 유입되는 전류(i1)는 수평편향코일(9),(9')을 통해 정류회로(30)로 인가되며 다이오드(D1)를 경유하여 보정코일(22), (22')에 흐르게 되어 A 또는 B의 어느 방향에서 전류가 유입되는 반드시 정류회로(30)의 P1지점에서 P2지점으로 흐르게 되어 대향설치된 보정편(23)(23')의 양단부분에는 극성이 형성됨으로써 자속이 발생하게 된다.First, as shown in FIG. 6, the current i1 flowing in the A direction is applied to the rectifier circuit 30 through the horizontal deflection coils 9 and 9 'and the correction coil via the diode D1. Both ends of the correction pieces 23, 23 'which face each other flow toward (22) and (22'), and flow from point P1 to point P2 of the rectifier circuit 30, in which current flows in either A or B direction. The polarity is formed in the portion, the magnetic flux is generated.
즉, 제5도의 (가)에 도시된 바와 같이 전자총 삽입구(3)의 상측에 설치된 보정부재(20)는 S,N극을 갖게되면 하측에 대항되게 설치된 부정부재(20')는 N,S극의 반대극성을 가지게 된다.That is, as shown in (a) of FIG. 5, when the correction member 20 provided on the upper side of the electron gun insertion hole 3 has S and N poles, the negative member 20 'provided to face the lower side is N, S. It has the opposite polarity.
따라서, 두 보정편(23)(23')이 대향되어 설치되어 있으므로 N극에서 S극으로 자속이 발생하여 R, B빔을 G빔 방향으로 좁혀주게 되어 음극선과 화면상에 역 트릴 레마 현상이 나타나게 된다.Therefore, since two correction pieces 23 and 23 'are disposed to face each other, magnetic flux is generated from the N pole to the S pole to narrow the R and B beams in the direction of the G beam so that the reverse trilema phenomenon occurs on the cathode ray and the screen. Will appear.
또한, 제5도의 (나)도는 보정코일(22), (22')의 권선방향을 반대로 감겨지게 하면 (가)도와는 반대로 극성이 보정부재(20)(20')에 나타나게 되며 이럴 경우 빔의 이동방향을 G빔과의 간격을 멀어지게 편향시킴으로써 음극선관 화면상에 정트릴레마화시킬 수 있는 것이다.In addition, (b) of FIG. 5 shows that when the winding directions of the correction coils 22 and 22 'are wound in reverse, the polarity is displayed on the correction members 20 and 20' as opposed to (a). By shifting the direction of movement away from the G-beam, it is possible to normalize the screen on the cathode ray tube screen.
특히, 수평편향코일(9)(9')에 흐르는 전류의 양에 비례하여 화면의 다른 특성에 영향을 거의 주지 않게 되어 안정된 화면을 제공하게 되는 것이다.In particular, in proportion to the amount of current flowing through the horizontal deflection coils 9 and 9 ′, the other characteristics of the screen are hardly affected, thereby providing a stable screen.
이상에서와 같이 이 고안에 따른 음극선관의 트릴 레마 가변장치에 의하면, ㄷ형 보정부재에 원통형의 보빈을 삽입하고, 상기 보빈상부에 보정코일이 권선된 보정편을 형성하고, 상기 보정편을 전자총 삽입구의 상하측에 설치하고, 상기 보정코일을 수직편향코일에 연결된 정류회로에 병렬로 접속되게 한 것이므로 전자총의 사이드 빔을 편향요크내에 입사하기 전에 빔의 간격을 조정하여 트릴레마를 최적의 조건으로 조절함으로써 선명한 화상을 제공할 수 있는 것이다.As described above, according to the trillama variable device of the cathode ray tube according to the present invention, a cylindrical bobbin is inserted into a c-shaped correction member, a correction piece wound with a correction coil is formed on the upper bobbin, and the correction piece is inserted into an electron gun. And the correction coils are connected in parallel to the rectifier circuit connected to the vertical deflection coil, so that the beam spacing is adjusted to the optimum conditions before the side beam of the electron gun is incident in the deflection yoke. By doing so, a clear image can be provided.
