본 고안은 디지탈 계측기 및 계산기 등에 소정의 숫자 및 기호등을 나타내기 위하여 사용되는 형광표시관에 관한 것으로, 특히 형광층의 휘도가 저하되지 않도록 개선된 형광표시관에 관한 것이다.The present invention relates to a fluorescent display tube used to display predetermined numbers and symbols, etc. in digital measuring instruments and calculators, and more particularly, to an improved fluorescent display tube so that the luminance of the fluorescent layer is not lowered.
종래의 형광표시관을 제1도에 도시된 바와 같이 세라믹 또는 그라스등으로 된 절연기판(1)의 표면에 도전성 피막으로 접속단자패턴(2)및 내부접속배선패턴(3)이 피착되고, 접속단자패턴(2)의 피착부를 제외한 부위에는 예를 들면 프리트 그라스류등을 절연성 피막(4)이 형성되며, 이때 절연성 피막(4)에 접속단자패턴(2)및 내부접속배선패턴(3)의 전기적 접속을 위한 통공(5)이 형성된다.As shown in FIG. 1, a connection terminal pattern 2 and an internal connection wiring pattern 3 are deposited on the surface of an insulating substrate 1 made of ceramic or glass, as shown in FIG. An insulating coating 4 is formed on the portion of the terminal pattern 2 except for the adhered portion, for example, fritgrass or the like. In this case, the insulating coating 4 of the connection terminal pattern 2 and the internal connection wiring pattern 3 is formed. A through hole 5 for electrical connection is formed.
그리고, 통공(5)이 형성된 절연성 피막(4)의 상면에는 양극세그먼트(6)가 피착되고, 이때 양극 세그먼트(6)의 일부는 통공(5)에 충진되면서 접속단자패턴(2)및 내부접속배선패턴(3)과 접속되어 도통되며, 양극 세그먼트(6)의 상면에는 형광층(7)이 형성되는 한편, 그리드(8)가 위치되는 절연성 피막(4)의 상면에는 도전성 접착제가 도포되고 이에 그리드(8)가 얹혀지며 프리트(9)가 그리드(8)위에 도포되어 소성됨으로서 그리드(8)가 접속단자패턴(2)과 전기적 접속 및 고정된다.An anode segment 6 is deposited on the upper surface of the insulating film 4 on which the through hole 5 is formed. At this time, a portion of the anode segment 6 is filled in the through hole 5, and the connection terminal pattern 2 and the internal connection are formed. A conductive layer is formed on the upper surface of the anode segment 6 and connected to the wiring pattern 3, while a conductive adhesive is applied to the upper surface of the insulating film 4 on which the grid 8 is located. The grid 8 is placed and the frit 9 is applied on the grid 8 and fired so that the grid 8 is electrically connected and fixed to the connection terminal pattern 2.
그러나, 상기와 같은 종래의 형광표시관은 그리드(8)를 고정시키기 위해 프리트(9)가 산화분위기에서 약 450∼500℃의 온도로 가열되어 소성될때 프리트(9)에서 발생되는 프리트 바인더가스가 형광층(7)의 표면에 흡착되어 형광층(7)의 휘도가 저하되었고, 특히 적색 형광층일 경우에는 열적 안정도가 낮아 450∼500℃로 프리트(9)가 소성될 때 휘도가 급격히 저하되었으며, 또한 산화분위기에서 가열됨으로써 그리드(8)가 산화되고, 프리트(9)가 도포되어 외관을 해치게 되는 등의 결함이 있었다.However, in the conventional fluorescent display tube as described above, the frit binder gas generated in the frit 9 is generated when the frit 9 is heated to a temperature of about 450 to 500 ° C. in the oxidation atmosphere to fix the grid 8. The luminance of the fluorescent layer 7 was lowered by being adsorbed on the surface of the fluorescent layer 7, and in particular, in the case of a red fluorescent layer, the thermal stability was low, and thus the luminance was rapidly decreased when the frit 9 was fired at 450 to 500 ° C. In addition, there is a defect that the grid 8 is oxidized by heating in an oxidizing atmosphere, and the frit 9 is applied to spoil the appearance.
따라서 본 고안은 이와 같은 종래의 결함을 감안하여 안출된 것으로서, 형광층의 오염 및 열분해에 의한 휘도의 저하현상이 없고, 그리드가 산화되지 않음은 물론 외관이 미려하게 된 형광표시관을 제공하는데 그 목적이 있다.Accordingly, the present invention was devised in view of such a conventional defect, and provides a fluorescent display tube which does not have a phenomenon of deterioration of luminance due to contamination of the fluorescent layer and thermal decomposition, and does not oxidize the grid and has a beautiful appearance. There is a purpose.
상기의 목적을 달성하기 위하여 본 고안은 그 상면에 접속단자패턴과 내부접속배선패턴과 절연성 피막과 양극 세그먼트 및 형광층이 순차적으로 적층된 절연기판과, 이에 고정되는 그리드를 구비하여 된 형관표시관에 있어서, 상기 접속단자패턴에 전극판이 도전성 접착제에 의해 전기적 접속되고, 상기 전극판 위에 상기 그리드가 용접된 점에 그 특징이 있다.In order to achieve the above object, the present invention provides an insulated display tube having an insulating substrate on which a connection terminal pattern, an internal connection wiring pattern, an insulating film, an anode segment, and a fluorescent layer are sequentially stacked, and a grid fixed thereto. The electrode plate is characterized in that the electrode plate is electrically connected to the connection terminal pattern by a conductive adhesive, and the grid is welded on the electrode plate.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 따른 형광표시관을 보인 단면도로서, 이에 도시된 바와 같이 세라믹 또는 그라스로된 절연기판(11)의 상면에 접속단자패턴(12)및 내부접속배선패턴(13)이 피착되며, 필라멘트 서포트, 내부접속배선패턴(13), 접속단자패턴(12)및 그리드(20)의 전기적접속을 위한 부위를 제외하고 프리트성분에 흑색계통의 안료등이 혼합된 절연성피막(14)이 도포되되, 이에 접속단자패턴(12)및 내부접속 배선패턴(13)의 전기적 접속을 위한 통공(17)이 형성된다. 또한 그리드(20)등과 같은 금속제와 전기적 접속이 되는 부위에는 도전성 접착제(15)가 도포되고, 이에 얇은 박판으로된 전극판(16)이 얹혀진다.2 is a cross-sectional view illustrating a fluorescent display tube according to the present invention, in which a connection terminal pattern 12 and an internal connection wiring pattern 13 are deposited on an upper surface of an insulating substrate 11 made of ceramic or glass. The insulating film 14 is mixed with a pigment of black color in the frit component, except for the filament support, the internal connection wiring pattern 13, the connection terminal pattern 12, and the area for the electrical connection of the grid 20. However, the through hole 17 for the electrical connection between the connection terminal pattern 12 and the internal connection wiring pattern 13 is formed. In addition, a conductive adhesive 15 is applied to a portion that is in electrical connection with a metal such as the grid 20, and a thin thin electrode plate 16 is placed thereon.
여기에서 상기 전극판(16)은 그라스와 열팽창계수가 비슷한 426합금등으로 되는 것이 바람직하다. 이때, 상기 전극판(16)은 소성공정에서 프리트가 주성분인 절연성 피막(14)이 용융된후, 냉각되면서 절연성 피막(14)에 고정되며, 도전성 접착제(15)를 통해 접속단자패턴(12)에 전기적으로 접속되게 된다.Herein, the electrode plate 16 is preferably made of a 426 alloy having a similar coefficient of thermal expansion to glass. At this time, the electrode plate 16 is fixed to the insulating film 14 while being cooled after melting the insulating film 14, the main component of frit in the firing process, the connection terminal pattern 12 through the conductive adhesive 15 Is electrically connected to the.
그리고, 내부접속배선패턴(13)의 상부에 형성된 통공(17)의 주연부 즉, 절연성 피막(14)의 통공(17)의 주연부에는 양극 세그먼트(18) 및 형광층(19)이 순차적으로 도포되어 형성되고, 그리드(20)및 팔라멘트 서포트등의 금속부품이 상기 전극판(16)에 용접된다.The anode segment 18 and the fluorescent layer 19 are sequentially applied to the periphery of the through hole 17 formed on the inner connection wiring pattern 13, that is, the periphery of the through hole 17 of the insulating coating 14. And metal parts such as a grid 20 and a filament support are welded to the electrode plate 16.
이와 같은 본 고안의 형광표시관은 그리드(20)를 고정시키기 위하여 프리트를 도포 및 소성하지 않고 전극판(16)에 그리드(20)를 직접 용접하여 고정함으로써 프리트 바인더가스가 발생되지 않아 형광층(19)의 오염이 방지되고 휘도가 저하되는 현상이 방지됨은 물론 고열에 의한 형광층(19)의 휘도저하 현상이 방지되며, 그리드(20)가 산화되지 않는다.The fluorescent display tube of the present invention does not generate frit binder gas by directly welding and fixing the grid 20 to the electrode plate 16 without applying and firing frit to fix the grid 20. Contamination of 19) is prevented and a phenomenon in which the luminance is lowered is prevented, as well as a phenomenon in which the luminance of the fluorescent layer 19 is reduced due to high heat, and the grid 20 is not oxidized.
또한, 내부에 프리트가 도포되어 있지 않아 외관이 미려하게 될 뿐만아니라 프리트의 도포공정 및 소성공정을 수행하지 않아 작업성이 간편하고, 생산성을 향상시킬 수 있게 되는 등의 효과가 있다.In addition, since the frit is not coated inside, the appearance is not only beautiful but also the workability and productivity can be improved since the frit coating process and the firing process are not performed.
