본 발명은 평면브라운관의 판넬 및 그 제조방법에 관한 것으로 특히 레일을 판넬에 일체로 성형함으로써 레일의 가공이 용이하도록 한 것이다.The present invention relates to a panel of a flat brown tube and a method of manufacturing the same, in particular to facilitate the processing of the rail by integrally molding the rail to the panel.
종래 브라운관의 새도우 마스크 고정장치를 제 1 도에 의하여 설명하면, 제 1 도는 전면으로 방폭 특성을 유지시키기 위하여 방폭유리(2)를 부착한 판넬(1)과 상기 판넬(1)에 네크부가 일체로 형성된 판넬(4)이 실링(Sealing)된 브라운관으로, 상기 네크부(3)에 봉입된 전자총(6)의 R,G,B 3색의 전자빔(5)을 판넬(1) 쪽으로 방사시켜 판넬의 부착된 형광체를 발광시키는 구조로 되어 있다.Referring to FIG. 1, a shadow mask fixing device of a conventional CRT is illustrated in FIG. The formed panel 4 is a sealed brown tube, and R, G, B three-color electron beams 5 of the electron guns 6 enclosed in the neck part 3 are radiated toward the panel 1 to form a panel. It is a structure which makes the attached fluorescent substance emit light.
상기 판넬(1)에는 공극 현상 또는 원형의 작은 구멍이 무수히 뚫린 새도우 마스크(7)가 판넬과 일정 간격을 유지시키도록 지지하는 레일(8)에 부착되어 있으며, 새도우마스크(7)를 지지하는 레일(8)은 프리트그라스(Frit Glass)(9)에 의해 판넬(1)에 접착 고정되어 있다.The panel 1 is attached to the rail 8 supporting the shadow mask 7 in which voids or circular small holes are innumerably maintained at a predetermined distance from the panel, and supporting the shadow mask 7. (8) is adhesively fixed to the panel (1) by frit glass (9).
이와 같이 형성된 평면 브라운관의 판넬(1)은 제 2 도와 같이 판넬(1)에 레일(8)을 프리트 그라스(Frit glass)(9)로 접착하여 고정하였다.The panel 1 of the flat CRT formed as described above was fixed by bonding the rails 8 to the panel 1 with frit glass 9 as in the second diagram.
이를 구체적으로 설명하면 평면으로 형성된 판넬(1)에 철재이면서 V자형으로 제작된 레일(8)을 프리트그라스(9)로 접착하였다.Specifically, the rail 8 made of steel and V-shaped to the panel 1 formed in the plane was bonded with fritgrass 9.
그리고, 판넬(1)에 접착된 레일(8)을 연마하여 판넬(1)과 일정 간격을 유지토록 연마한 상태에서 연마된 레일(8)에 새도우 마스크(7)를 용접하여 부착하였다.Then, the shadow mask 7 was welded and attached to the polished rail 8 in a state in which the rail 8 adhered to the panel 1 was polished and polished to maintain a predetermined distance from the panel 1.
즉, 종래에는 레일(8)을 판넬과는 별개로 구성하여 레일을 판넬에 부착시키는 과정에서 새도우마스크(7)를 부착하기 위하여 레일(8)을 V자형으로 제작하여야 하는 문제점이 있고, 또한 상기 레일(8)을 접착제에 의하여 판넬(8)에 부착하여야 하는 문제점이 있으며, 또한 상기 레일(8)을 연마함에 있어 철재이기 때문에 연마작업에 문제점이 있었다.That is, in the related art, the rail 8 is formed separately from the panel, and thus, the rail 8 is formed in a V shape in order to attach the shadow mask 7 in the process of attaching the rail to the panel. There is a problem in that the rail (8) to be attached to the panel (8) by an adhesive, and there is a problem in polishing work because it is iron in polishing the rail (8).
또한 종래의 브라운관은 판넬과 새도우마스크를 일정간격 유지하기 위하여 레일을 일정두께로 만들기 위해 연마작업을 해야 하는데 연마작업시 일정두께를 유지하기 힘들고, 레일의 주성분이 철재여서 브라운관에 열처리를 할 경우 판넬(1)과 레일(8)의 열팽창계수가 서로 상이하여 판넬(1)의 휨현상이 발생함으로써 전자빔(5)이 원래 위치가 아닌 서로 다른 시점에 방사되어 형광체를 발광시켜 타색불량을 발생시키는 문제점이 발생되었다.In addition, the conventional CRT should be polished to make the rail to a certain thickness in order to maintain the panel and shadow mask at regular intervals, but it is difficult to maintain a certain thickness during polishing, and the main component of the rail is steel, so when the heat treatment is carried out on the CRT, The thermal expansion coefficients of (1) and the rails (8) are different from each other, so that warpage of the panel (1) occurs, which causes the electron beam (5) to be radiated at different points in time, rather than to the original position, to cause phosphors to emit light. Occurred.
본 발명은 상기 문제점을 해결하고자 레일(102)의 재질을 판넬(101)의 재질과 동일한 재질인 유리(glass)로 기존의 판넬 금형시 레일을 판넬에 일체로 성형되도록 함으로써 판넬 가공시 일정 두께를 만들어 성형할 수 있다.The present invention is to solve the above problems by making the rail 102 integrally formed in the panel when the panel mold in the panel of the material (glass) of the same material as the material of the panel 101 to a certain thickness during panel processing Can be made and molded.
상기 평면 브라운관의 판넬 제조방법을 다음 실시예의 의하여 설명한다.The panel manufacturing method of the said flat CRT is demonstrated by the following Example.
(실시예)(Example)
레일이 판넬에 일체로 형성되도록 하는 레일금형이 일체로 형성된 판넬 금형 제작 과정과, 상기 판넬 금형 제작과정으로 형성된 판넬금형에 의하여 판넬을 성형하는 판넬성형과정으로 이루어졌다.A panel mold manufacturing process in which a rail mold is integrally formed in a panel, and a panel molding process for forming a panel by a panel mold formed by the panel mold manufacturing process.
이와 같이 제조되는 평면브라운관의 판넬은 제조공정에 있어서 판넬(101)에 레일(102)을 일체로 형성함으로써 종래와 같이 판넬에 레일을 접착제로 부착하는 공정을 제거할 수 있기 때문에 생산 원가를 줄일 수 있다.The panel of the flat brown tube manufactured as described above can reduce the production cost because the rail 102 is integrally formed on the panel 101 in the manufacturing process, thereby eliminating the process of attaching the rail to the panel by adhesive. have.
이상과 같이 본 발명은 종래 기술보다 제조공정을 줄일 수 있을 뿐만 아니라 연마작업의 불편을 해소할 수가 있고, 또한 판넬과 열 평창계수가 동일한 유리재질을 사용함으로써 열처리시 판넬의 휨을 방지할 수 있어 전자빔 방사시 타색 불량을 방지하는 효과를 얻을 수 있다.As described above, the present invention can not only reduce the manufacturing process but also eliminate the inconvenience of polishing operation, and also prevent the warpage of the panel during heat treatment by using the same glass material as the panel and thermal flatness coefficient. When spinning, it is possible to obtain an effect of preventing poor color.
