Description
본 발명은 편향요크에 관한 것으로서, 보다 상세하게는 화면왜곡을 안정되게 보정할 수 있는 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a deflection yoke capable of stably correcting screen distortion.
일반적으로 TV수상기 또는 모니터의 음극선관(CRT)에 사용되는 편향요크는 새들-트로이달(saddle toroidal type), 새들-새들형등 여러 가지 형태로 되어 있다.In general, the deflection yoke used in a cathode ray tube (CRT) of a TV receiver or a monitor has various forms such as a saddle toroidal type and a saddle-saddle type.
이러한 편향요크는 도 1에 나타내 보인 바와 같이, 좌,우 대칭형으로 되어 하나로 합체되는 한쌍의 코일 세퍼레이터(10)을 구비한다.As shown in FIG. 1, the deflection yoke has a pair of coil separators 10 which are symmetrical in left and are integrated into one.
코일 세퍼레이터(10)는, 음극선관(1)의 스크린면(1a)에 결합되는 스크린부(11)와, 리어 커버(12) 그리고 이 리어 커버(rear cover;12)의 중심부로부터 연장 형성되어 음극선관(1)의 전자총부(1b)에 결합되는 네크부(13)으로 이루어진다.The coil separator 10 is formed by extending from a screen portion 11 coupled to the screen surface 1a of the cathode ray tube 1, a rear cover 12, and a central portion of the rear cover 12. It consists of a neck part 13 coupled to the electron gun part 1b of the tube 1.
코일 세퍼레이터(10)의 내측에는 전자빔을 수평방향으로 편향시키기 위한 수평편향자계를 발생하는 한쌍의 수평편향코일(14)이 마련되며, 외측에는 전자빔을 수직방향으로 편향시키기 위한 수직편향자계를 발생시키는 수직편향코일(15)이 마련된다.Inside the coil separator 10 is provided a pair of horizontal deflection coils 14 for generating a horizontal deflection magnetic field for deflecting the electron beam in the horizontal direction, and an outer side for generating a vertical deflection magnetic field for deflecting the electron beam in the vertical direction. The vertical deflection coil 15 is provided.
그리고 수직편향코일(15)을 감싸도록 장착되어 수직편향코일에서 발생되는 수직편향자계를 강화시킬 수 있도록 자성체로 형성되는 한쌍의 페라이트코어(16)가마련된다.Then, a pair of ferrite cores 16 formed of a magnetic material are provided to surround the vertical deflection coil 15 so as to reinforce the vertical deflection magnetic field generated in the vertical deflection coil 15.
한편, 미스컨버젼스를 보정하기 위하여 수평편향코일(14)에는 핀 쿠션 자계가 발생하도록 코일 형상을 설계하며, 수직편향코일(15)에는 배럴자계가 발생하도록 코일 형상을 설계함으로써 도 2에서와 같이 자계가 발생하도록 하고 있다.Meanwhile, in order to correct misconvergence, the coil shape is designed to generate a pin cushion magnetic field in the horizontal deflection coil 14, and the coil shape is designed to generate a barrel magnetic field in the vertical deflection coil 15, as shown in FIG. 2. Is going to occur.
그러나 이러한 자계를 통해 미스컨버젼스를 보정함에 있어서는, 근래에 평면에 가까운 음극선관의 구조를 취하는 것에 의해서는 도 3에서와 같인 핀쿠션 화면왜곡이 발생되는 바, 도 4에서와 같이 스크린부(11)에 강한 핀쿠션 자계가 형성되도록 하여 화면왜를 보상하도록 하고 있다.However, in correcting misconvergence through such a magnetic field, a pincushion screen distortion as shown in FIG. 3 is generated by taking a structure of a cathode ray tube close to a plane in recent years. As shown in FIG. A strong pincushion magnetic field is formed to compensate for the screen distortion.
그리고 스크린부(11)에 강한 핀쿠션 자계를 형성함에 의해 발생되는 미스컨버젼스를 보상하기 위하여 네크부(13)측에 자성편을 이용하여 배럴화 자계를 형성시킴으로써 도 4에서와 같은 자계가 형성되도록 하고 있다.In addition, in order to compensate for the misconvergence generated by forming a strong pincushion magnetic field on the screen portion 11, a magnetic field such as that shown in FIG. 4 is formed by forming a barrelized magnetic field using a magnetic piece on the neck portion 13 side. have.
그러나 이러한 화면왜곡 및 미스컨버젼스 보상방법은, 화면의 코너부분의 편향율을 수평축보다 약하게 함으로써 빔의 편향력을 떨어뜨려 화면왜곡을 보상하도록 하는 것이기 때문에 코너부의 컨버젼스 및 상,하 화면왜곡이 변화되는 문제점이 야기된다.However, since the screen distortion and misconvergence compensation method lowers the deflection force of the beam by making the deflection ratio of the corner portion of the screen weaker than the horizontal axis, the convergence of the corner portion and the upper and lower screen distortion are changed. The problem is caused.
본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 창출된 것으로서, 미스컨버젼스 및 화면왜를 안정되게 보상할 수 있으며, 특히 기타 특성 변화에 영향을 끼치지 않는 편향요크를 제공함에 그 목적이 있다.The present invention has been made to solve such problems in the related art, and has an object to provide a deflection yoke that can stably compensate for misconvergence and screen distortion, and does not affect other characteristic changes.

이와같은 목적을 달성하기 위하여 본 발명은 음극선관의 스크린면에 결합되는 스크린부와, 리어 커버 그리고 이 리어 커버의 중심면으로부터 연장 형성되어 음극선관의 전자총부에 결합되는 네크부로 이루어진 코일 세퍼레이터와; 상기 코일 세퍼레이터의 내,외주면에 마련되며, 수평편향자계와 수직 편향자계를 형성하는 수평 및 수직편향코일과; 상기 수평편향코일에 직렬 접속되어 화면상의 왜곡을 보정하도록 보빈과 이에 권선되는 코일로 이루어진 한쌍의 보정편;을 포함하여 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention provides a coil separator comprising a screen portion coupled to the screen surface of the cathode ray tube, a rear cover and a neck portion extending from the center surface of the rear cover and coupled to the electron gun portion of the cathode ray tube; Horizontal and vertical deflection coils provided on inner and outer circumferential surfaces of the coil separator to form a horizontal deflection magnetic field and a vertical deflection magnetic field; And a pair of correction pieces consisting of a bobbin and a coil wound thereon to be connected in series with the horizontal deflection coil to correct distortion on the screen.
본 발명의 바람직한 한 특징은, 상기 한쌍의 보정편은, 음극선관의 스크린면을 기준으로 하여 코일 세퍼레이터의 스크린부 외측에 위치되는 것에 있다.One preferable feature of the present invention is that the pair of correction pieces are positioned outside the screen portion of the coil separator with respect to the screen surface of the cathode ray tube.
이와같은 본 발명의 특징적인 구성 및 이에따른 작용효과는 후술하는 첨부된 도면을 참조한 발명의 상세한 설명을 통해 더욱 명확해 질 것이다.Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.
도 5 및 도 6은 본 발명에 따른 편향요크를 개념적으로 나타낸 정면도 및 측면도이고, 도 7은 본 발명 편향요크를 통한 화면 왜곡 보상을 보인 개념도이다. 그리고 이하에서는 도 1을 참조하여 설명한다.5 and 6 are a front view and a side view conceptually showing a deflection yoke according to the present invention, Figure 7 is a conceptual diagram showing a screen distortion compensation through the deflection yoke of the present invention. Hereinafter, a description will be given with reference to FIG. 1.
먼저 도 1을 참조하면, 좌,우 대칭형으로 되어 하나로 합체되는 한쌍의 코일 세퍼레이터(10)을 구비한다.First, referring to FIG. 1, a pair of coil separators 10, which are symmetrical left and right, are merged into one.
코일 세퍼레이터(10)는, 음극선관(1)의 스크린면(1a)에 결합되는 스크린부(11)와, 리어 커버(12) 그리고 이 리어 커버(rear cover;12)의 중심부로부터 연장 형성되어 음극선관(1)의 전자총부(1b)에 결합되는 네크부(13)으로 이루어진다.The coil separator 10 is formed by extending from a screen portion 11 coupled to the screen surface 1a of the cathode ray tube 1, a rear cover 12, and a central portion of the rear cover 12. It consists of a neck part 13 coupled to the electron gun part 1b of the tube 1.
코일 세퍼레이터(10)의 내측에는 전자빔을 수평방향으로 편향시키기 위한 수평편향자계를 발생하는 한쌍의 수평편향코일(14)이 마련되며, 외측에는 전자빔을 수직방향으로 편향시키기 위한 수직편향자계를 발생시키는 수직편향코일(15)이 마련된다.Inside the coil separator 10 is provided a pair of horizontal deflection coils 14 for generating a horizontal deflection magnetic field for deflecting the electron beam in the horizontal direction, and an outer side for generating a vertical deflection magnetic field for deflecting the electron beam in the vertical direction. The vertical deflection coil 15 is provided.
그리고 수직편향코일(15)을 감싸도록 장착되어 수직편향코일에서 발생되는 수직편향자계를 강화시킬 수 있도록 자성체로 형성되는 한쌍의 페라이트코어(16)가 마련된다.In addition, a pair of ferrite cores 16 are mounted to surround the vertical deflection coil 15 and formed of a magnetic material to reinforce the vertical deflection magnetic field generated in the vertical deflection coil.
한편, 전술한 수평편향코일(14)에는 실질적으로 본 발명의 특징적인 요소를 갖고 있는 것으로서, 화면상의 왜곡 즉, 화면왜를 보상하도록 하기 위한 것으로서, 보빈(110)과 이에 권선되는 코일(120)로 이루어진 한쌍의 보정편(100)이 직렬 접속된다.On the other hand, the above-described horizontal deflection coil 14 has substantially the characteristic elements of the present invention, to compensate for the distortion on the screen, that is, the screen distortion, the bobbin 110 and the coil 120 wound thereon The pair of correction pieces 100 which consist of is connected in series.
이때 보정편(100)의 형성위치는 음극선관(1)의 스크린면(1a)을 기준으로 할대 코일 세퍼레이터(10)의 스크린부(11) 외측에 위치되도록 함이 바람직하다.At this time, it is preferable that the formation position of the correction piece 100 is positioned outside the screen portion 11 of the coil coil separator 10 based on the screen surface 1a of the cathode ray tube 1.
또한 좀더 큰 자계 형성을 위하여 보정편(100)의 보빈(110) 내측에 페라이트 재질등의 자성체를 더 마련함이 바람직하다.In addition, it is preferable to further provide a magnetic material such as ferrite material inside the bobbin 110 of the correction piece 100 to form a larger magnetic field.
이와같이 구성된 본 발명은, 수평편향코일(14)에 직렬 접속된 보정편(100)에 전류가 인가되면 스크린부(11)측에서 수평편향코일(14)과 동일한 자계가 발생되고, 이에따라 빔을 좀더 편향시켜주는 효과를 얻게된다.According to the present invention configured as described above, when a current is applied to the correction piece 100 connected in series to the horizontal deflection coil 14, the same magnetic field as that of the horizontal deflection coil 14 is generated on the screen 11 side. You get a biasing effect.
즉, 수평편향코일(14)을 지난 빔이 보정편(100)에 의해 재차 편향됨으로써 화면왜를 배럴화 시키기 때문이다.In other words, the beam passing through the horizontal deflection coil 14 is deflected by the correction piece 100 again, thereby barreling the screen distortion.
이를 통해서는 도 7에 점선으로 나타내 보인 바와 같이 화면왜가 보상되며, 특히 코너부위에서의 미스컨버젼스 및 화면왜의 특성변화가 발생되지 않게된다.Through this, the screen distortion is compensated as shown by a dotted line in FIG. 7, and in particular, the misconvergence of the corner portion and the characteristic change of the screen distortion are not generated.
상술한 바와 같이 본 발명에 따른 편향요크에 의하면, 수평편향코일에 직렬 접속된 한쌍의 보정편을 통해 화면왜를 배럴화시킬 수 있게되어 화면왜의 보상을 안정되게 수행할 수 있는 이점이 있다.According to the deflection yoke according to the present invention as described above, it is possible to barrel the screen distortion through a pair of correction pieces connected in series to the horizontal deflection coil, thereby providing an advantage of stable compensation of the screen distortion.
또한 화면왜의 보상과정에서 코너부분의 미스컨버젼스 및 화면액 특성에 변화를 주지않게되어 별도의 보정편을 마련할 필요가 없는 이점이 있다.In addition, there is no need to prepare a separate correction piece because it does not change the misconvergence of the corner portion and the characteristics of the screen liquid during the screen distortion compensation process.
