본 고안에 음극선관의 새도우 마스크에 관한 것으로 보다 상세하게는, 음극선관내에 배치되는 새도우 마스크의 부착구조에 관한 것이다.The present invention relates to a shadow mask of a cathode ray tube, and more particularly, to an attachment structure of a shadow mask disposed in a cathode ray tube.
일반적으로 새도우 마스크형 음극선관은 제 3 도에 나타낸 바와 같이 장방형의 패널부(1)와, 상기한 패널부(1)에서 이어지는 원추형상의 펀넬부(2)와, 상기한 펀넬부(2)에서 이어지는 네크부(3)로 형성된다.In general, a shadow mask type cathode ray tube is formed in a rectangular panel portion 1, a conical funnel portion 2 that is continued from the panel portion 1, and a funnel portion 2 as shown in FIG. It is formed by the neck portion 3 which follows.
3개의 전자비임(4)을 발생시키는 전자총(5)은 네크부(3)내에 위치되고, 이들 전자비임(4)은 네크부(3)외측에 위치된 편향코일(6)에 의해 편향되어 새도우 마스크(7)의 구역에서 실제로 서로 교차된 후에 패널부(1)내측에 형성된 형광막(8)에 부딪혀 화상을 나타낸다.An electron gun 5 for generating three electron beams 4 is located in the neck portion 3, and these electron beams 4 are deflected by a deflection coil 6 located outside the neck portion 3 and shadowed. After actually crossing each other in the region of the mask 7, the image is hit by the fluorescent film 8 formed inside the panel 1.
상기한 새도우 마스크(7)는 평면상의 극히 얇은 두께(보통 0.13-0. 18㎜)로 광식각 공법에 의해서 미리 수십만개의 구멍을 뚫어 프레스 가공하여 구면상으로 형성시킨 다음, L지상의 프레임(9)의 측벽 전체둘레에 걸쳐 밀접하게 부착되어 있다.The shadow mask 7 has a planar extremely thin thickness (usually 0.13-0.18 mm) and is formed into a spherical shape by pressing hundreds of thousands of holes in advance by a photoetching method, and then forming an L-shaped frame 9 Are closely attached over the entire circumference of the side wall.
종래에 이러한 새도우 마스크의 부착은 제 4 도에 나타낸 바와 같이 절개홈(10)을 형성한 후 절곡하여 형성된 측벽(7')을 프레임(9)의 상측에 밀접하게 감아 붙여 지지시키게 된다. 그러나, 상기한 바와 같은 구성은 프레임(9)과 새도우 마스크(7)의 부착후에 구멍(H)내로 새도우 마스크(7)내에서의 전위가 방출되어 패널부(1)내측의 전위와 충돌되는 현상이 일어나게 된다.Conventionally, the shadow mask is attached to the side wall 7 'formed by bending after forming the cutout groove 10 as shown in FIG. 4 to closely support the upper side of the frame (9). However, the above-described configuration is a phenomenon in which the potential in the shadow mask 7 is released into the hole H after the attachment of the frame 9 and the shadow mask 7 to collide with the potential inside the panel 1. This will happen.
상기한 바와 같은 현상은 음극선관 동작초기에 관내에 불균형한 전위대가 형성되어 패널부의 코너 및 장, 단변중앙으로부터 이상발광 현상을 일으키는 등의 문제점이 있다.The above phenomenon has a problem that an unbalanced electric potential band is formed in the tube at the beginning of the operation of the cathode ray tube, causing abnormal light emission from the corners, the long sides, and the short sides of the panel portion.
본 고안은 상기한 바와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 패널부의 코너 및 장, 단변의 중앙에서 발생되는 이상발광 현상이 나타나지 않도륵 하는 음극선관의 새도우 마스크를 제공하는데 있다. 상기한 바와 같은 목적을 실현하기 위하여 본 고안은 마스크 구멍이 뚫어진 중앙부와 그 주변에 형성되는 스커트부로 이루어지는 새도우 마스크에 있어서, 상기한 스커트부 코너에는 양측에 좁은 폭을 갖는 노치가 형성된 덮개편이 양 스커트부틀 덮도록 구성되는 음극선관의 새도우 마스크를 제공한다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a shadow mask of a cathode ray tube that does not appear abnormal emission phenomenon occurring in the center of the corners, long sides, short sides of the panel portion. To provide. In order to achieve the above object, the present invention provides a shadow mask comprising a center portion in which a mask hole is drilled and a skirt portion formed around the skirt portion, wherein the skirt portion has a cover piece formed with notches having a narrow width at both sides. Provided is a shadow mask of a cathode ray tube configured to be boot covered.
이하에 본 고안의 바람직한 실시예를 첨부된 도면에 따라서 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제 1 도에 본 고안에 다른 음극선관의 새도우 마스크를 나타내는 요부 평면도로서, 부호(11)은 새도우 마스크를 나타내고 있다.In FIG. 1, the principal part plan view which shows the shadow mask of the cathode ray tube which concerns on this invention is shown, The code | symbol 11 has shown the shadow mask.
상기한 새도우 마스크(11)는 수십만개의 마스크 구멍이 뚫어진 중앙부(12)와 그 주변에 연장되는 스커트 부(13)로 구성된다. 상기한 스커트 부(13)의 코너에는 양측에 폭이 좁은 노치(14), (14')가 형성된 덮개편(15)이 형성되어 있다. 상기한 노치(14),(14')는 ""현상으로 하는 것이 바람직하다.The shadow mask 11 is composed of a central portion 12 through which hundreds of thousands of mask holes are drilled and a skirt portion 13 extending around the center portion 12. The cover piece 15 in which the narrow notches 14 and 14 'were formed in the both sides at the corner of the said skirt part 13 is formed. The notches 14, 14 'described above are " "It is desirable to be a phenomenon.
상기한 바와 같이 구성되는 본 고안에 따른 음극선관의 새도우 마스크는 제 2 도에 나타낸 바와 같이 프레임(9)의 측벽에 부착된다. 이때 새도우 마스크(11)는 스커트부(13)가 먼저 프레임(9)의 측벽에 부착되고, 그 위에 덮개편(15)이 양측의 스커트부(13)을 덮는 형태로 부착되므로 전위의 방출을 방지하게 되어 음극선관 동작 초기에 불균형한 전위대에 의해 발생되는 이상발광현상은 나타나지 않게 된다.The shadow mask of the cathode ray tube according to the present invention constructed as described above is attached to the side wall of the frame 9 as shown in FIG. 2. In this case, the shadow mask 11 is first attached to the side wall of the frame 9 and the cover piece 15 is attached to cover the skirt part 13 on both sides, thereby preventing the release of dislocations. As a result, abnormal luminescence phenomena caused by an unbalanced potential band at the beginning of the cathode ray tube operation do not appear.
또 본 고안은 상기한 덮개편(15)이 스커트부(13)를 완전하게 덮어 버리므로 주름등이 생기지 않는 등의 이점도 있다.In addition, the present invention also has the advantage that the cover piece 15 completely covers the skirt portion 13 so that wrinkles and the like do not occur.
