본 고안은 형광표시관에 관한 것으로서, 보다 상세하게는 유리기판 상에 형성되는 배선패턴과 그 위로 배치되는 전극부품 사이의 도전접촉을 개선한 형광표시관에 관한 것이다.The present invention relates to a fluorescent display tube, and more particularly, to a fluorescent display tube with improved conductive contact between a wiring pattern formed on a glass substrate and an electrode component disposed thereon.
형광표시관은 외부와 격리된 용기의 내부에 열전자를 방출하는 캐소오드와, 열전자에 의해 빛을 발하는 형광체를 보유하는 애노오드를 대치시키고, 이들 사이에 그리드전극을 배치시킨 구조로 되어 있어서 캐소오드로부터 방사되는 열전자가 그리드에 의해 애노오드쪽으로 인도되어 형광체에 충돌됨으로써 문자나 기호 등을 표시하는 소자이다.The fluorescent display tube has a structure in which a cathode which emits hot electrons and an anode which holds a phosphor emitting light by hot electrons is replaced with a grid electrode disposed between the cathode and the inside of the container, which are isolated from the outside. The hot electrons radiated from the device are guided toward the anode by the grid and collide with the phosphor to display letters, symbols, and the like.
형광표시관에서 표시부로 되는 양극은 유리기판상에 형성된 배선패턴의 소정부위에 설치되어 있고, 또 그리드나 캐소오드등은 대응하는 배선패턴과 은페이스트를 개재하여 전기적인 접촉이 이루어지게 되어 있다.The anode serving as the display portion in the fluorescent display tube is provided at a predetermined portion of the wiring pattern formed on the glass substrate, and the electrical contact between the grid and the cathode is made through the corresponding wiring pattern and silver paste.
제 2 도는 종래의 형광표시관에서 볼수 있는 도전접속예를 도시한다.2 shows an example of conductive connection seen in a conventional fluorescent display tube.
유리기판(G)의 상면에는 배선패턴(B)이 부설되고, 이 배선패턴(B)의 주변은 절연층(I)에 의해 둘러 쌓여진다.The wiring pattern B is provided on the upper surface of the glass substrate G, and the periphery of this wiring pattern B is surrounded by the insulating layer I.
유리기판(G)상에 배치되는 그리드(C)등은 배선패턴(B)과의 사이에 도전매개물을 개재하여 전기적 접촉이 이루어질 수 있게 되어 있으며, 통상은 도전매개물로서 겔상의 은페이스트(S)를 개재하여 배선패턴(B)과 접촉된 다음 프리트(F)에 의해 고정 부착된다.The grid (C) or the like disposed on the glass substrate (G) is capable of making electrical contact with the wiring pattern (B) via the conductive medium. Usually, the silver paste (S) of the gel form as the conductive medium. Is contacted with the wiring pattern (B) via and then fixedly attached by the frit (F).
그런데 프리트(F)는 소결 응고되어 해당 부품을 고정하여 주는 것이고, 이것은 소성공정에서 열수축성을 나타낸다. 따라서 소결된 후에는 도포범위가 좁아져서 그 밑에 존재하는 은페이스트(S)를 외부로 노출시키게 되는 경우가 있으며, 이 과정에서 노출되어진 은페이스트(S)는 가열되면 용해되는 물질이므로 소성공정에서 녹아 퍼져서 외관을 손상시키거나 심한 경우, 해당부품의 전기적 접촉 불량이나 단선을 유발하는 문제점을 일으키게 된다.By the way, the frit (F) is sintered and solidified to fix the component, which shows heat shrinkability in the firing step. Therefore, after sintering, the application range becomes narrow and the silver paste (S) existing under it may be exposed to the outside, and the silver paste (S) exposed in this process is a material that is dissolved when heated, so it melts in the firing process. Spreading damages the appearance or, in severe cases, causes problems such as poor electrical contact or disconnection of the parts.
본 고안의 목적은 상기와 같은 종래의 도전접촉방식의 단점을 해결하기 위하여 열에 용해되지 않는 도전매개물에 의해 도전접촉을 개선한 형광표시판을 제공함에 있다.An object of the present invention is to provide a fluorescent display panel with improved conductive contact by a conductive medium that is not dissolved in heat in order to solve the disadvantage of the conventional conductive contact method as described above.
상기 목적에 따라, 본 고안은 배선패턴과 그리드 혹은 캐소오드와의 도전접촉부위에 ITO층을 프린트 인쇄하고, 그 위로 해당부품을 접촉시켜 프리트에 의해 지지되게 함으로써, 소결중에 도전매개물이 용해되지 않게 개선함에 그 특징이 있다.In accordance with the above object, the present invention prints an ITO layer on a conductive contact portion between a wiring pattern and a grid or a cathode, and contacts the component thereon to be supported by frit, so that the conductive medium does not dissolve during sintering. It is characterized by improvements.
이하 첨부된 도면에 따라 본 고안의 바람직한 실시예를 설명한다.Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings.
본 고안은 제 1 도에 도시한 바와 같이 유리기판(1)의 상면에 배선패턴(2)을 형성하고 그 주변을 절연층(3)으로 둘러 쌓은 다음, 전기한 배선패턴(2)에서 그리드 혹은 캐소오드의 단자(5)와 전기접촉되는 부위로 한정하여 도전매개물로서 ITO층(4)을 더 적층시킨 구조로 되어 있다.According to the present invention, as shown in FIG. 1, the wiring pattern 2 is formed on the upper surface of the glass substrate 1, and the periphery is surrounded by the insulating layer 3, and then the grid or It is a structure in which the ITO layer 4 is further laminated as a conductive medium, limited to a site in electrical contact with the terminal 5 of the cathode.
상기와 같이 적층된 ITO층(4)의 위로는 그리드나 캐소오드의 단자(5)가 얹혀져서 프리트(6)에 의해 고정된다. 여기서 전지한 ITO층(4)은 종래의 은페이스트와는 달리 융점이 높기 때문에 프리트(6)의 소결중에 용해되어 퍼지는 일이 생기지 않는다. 게다가 프리트(6)가 소결에 의한 열수축으로 ITO층(4)의 일부를 노출시키더라도 이것은 투명한 것이므로 외부에서 식별되지 않는다.Above the ITO layer 4 laminated as described above, a terminal 5 of a grid or a cathode is mounted and fixed by a frit 6. Unlike the conventional silver paste, the ITO layer 4 that has been batteryd has a high melting point, so that it does not dissolve and spread during the sintering of the frit 6. In addition, even if the frit 6 exposes a part of the ITO layer 4 by thermal contraction by sintering, it is transparent and is not identified from the outside.
따라서 ITO층(4)이 그리드나 캐소오드와의 도전매개물로 사용된 형광표시관은 프리트(6)가 소결공정에서 열수축되어도 전기적 접촉 불량이나 단선이 유발되지 않으면서도 외관의 손상까지 생기지 않게 된다.Therefore, in the fluorescent display tube in which the ITO layer 4 is used as a conductive medium with the grid or the cathode, even if the frit 6 is thermally contracted in the sintering process, the appearance of the fluorescent display tube does not occur even without causing poor electrical contact or disconnection.
또한, ITO층(4)은 프린트기법에 따라 형성되는 것이므로 종래의 은페이스트에 의존하는 방법에 비하여 특별한 제조원가의 상승을 초래하는 일도 없다.In addition, since the ITO layer 4 is formed by the printing technique, there is no increase in manufacturing cost in comparison with the conventional silver paste-based method.
이상과 같이 본 고안은 종래에 도전매개물의 용해가 원인으로 되었던 접촉 불량의 염려를 근본적으로 해결할 수 있고, 또 얻어지는 제품의 외관도 한층 향상되기 때문에 신뢰성있는 제품을 얻을 수 있게 한다.As described above, the present invention can fundamentally solve the concern of poor contact caused by the conventional dissolution of the conductive medium, and also improve the appearance of the obtained product, thereby making it possible to obtain a reliable product.
