본 고안은 형광표시장치에 관한한 것으로서, 보다 상세하게는 부품수의 절감을 도모할 수 있는 구조로 된 형광표시장치에 관한 것이다.The present invention relates to a fluorescent display device, and more particularly, to a fluorescent display device having a structure that can reduce the number of parts.

형광표시장치는 액정을 이용한 표시소자보다 휘도가 월등하게 우수한 이점이 있어서 측정기기 등의 디지탈표시로 사용되고 있다.Fluorescent display devices have an advantage of superior luminance over display elements using liquid crystals, and thus are used for digital display of measuring devices.

형광표시장치의 일반적인 구조는 제2도에 도시한 바와 같이 진공 밀봉되는 외위기(A)의 하측부에 기판(B)가 부착되고, 이 기관(B)에는 형광층(C)가 소정의 패턴을 이루어 형성되며, 또 형광층(C)의 상부에는 일정 간격을 두고 그리드(D)가 배치된다.In the general structure of the fluorescent display device, as shown in FIG. 2, the substrate B is attached to the lower side of the envelope A, which is vacuum sealed, and the fluorescent layer C is formed on the engine B by a predetermined pattern. The grid D is formed at a predetermined interval on the fluorescent layer C.

그리드(D)는 격자상의 전극체이며, 그 상부에는 상호 대향위치하는 캐소오드(E) 사이로 가설된 필라멘트(F)가 위치한다.The grid D is a lattice-shaped electrode body, and the filament F hypothesized between the cathodes E, which are mutually opposite to each other, is located thereon.

또한, 외위기(A)의 내측면에는 투명도전막(G)가 증착되어 있고, 이 투명도전막(G)에는 캐소오드(E)에서 연장된 콘택트포인트(H)가 접촉되어 있다.In addition, a transparent conductive film G is deposited on the inner surface of the envelope A, and a contact point H extending from the cathode E is in contact with the transparent conductive film G.

상기한 투명도전막(G)는 형광표시장치가 동작되면, 캐소오드(E)를 통하여 전압을 인가받아 팔라멘트(F)에서 방사되는 열전자를 반발시켜 그리드(D) 쪽으로 향하게 하는 역활을 한다.When the fluorescent display device is operated, the transparent conductive film G plays a role of applying a voltage through the cathode E to repel the hot electrons emitted from the filament F to face the grid D.

이러한 구조에 있어서, 필라멘트(F)가 통전 가열되면 열전자를 방출하게 되고, 이 열전자는 그리드(D)에의해 유인되어져 기판(B) 상의 형광체(C)로 충돌하게 되며, 그 결과로 형광체(C)는 빛을 발하게 되는 것이다.In this structure, when the filament F is energized and heated, it emits hot electrons, which are attracted by the grid D to collide with the phosphor C on the substrate B, and consequently the phosphor C ) Is to shine.

그런데 상기한 구조에 의하면 투명도전막(G)도 캐소오드 전압이 인가되게 하기 위한 콘택트포인트(H)를 필수적으로 갖추어야 하므로 부품수의 증가와 함께 조립수공의 번잡화를 초래하는 단점이 있다.However, according to the above structure, the transparent conductive film G must also have a contact point H for applying a cathode voltage, which leads to an increase in the number of parts and complicated assembly.

본 고안의 목적은 통상의 형광표시장치에 필요한 조립부품수를 줄여서 원가의 절감과 함께 조립수공의 간편화를 도모할 수 있는 구조의 형광표시장치를 제공함에 있다.It is an object of the present invention to provide a fluorescent display device having a structure that can reduce the number of assembly parts required for a conventional fluorescent display device and can simplify assembly work.

이에 따라, 본 고안은 외위기의 내측면에 통상적으로 증착 형성되는 투명도전막의 일측단을 상기한 외위기의 한쪽 내측벽면으로 연장하여 기관의 해당단자와 전기적으로 접촉시켜서 전위의 직류 혹은 펄스전압이 인가되게 구성함을 특징으로 한다.Accordingly, the present invention extends one side end of the transparent conductive film, which is usually formed on the inner surface of the envelope, to one inner wall surface of the envelope to electrically contact the corresponding terminal of the engine so that a direct current or pulse voltage of the potential is increased. Characterized in that it is configured to be applied.

이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 관련되는 형광표시장치의 구조를 나타내는 단면도로서, 형광체(1)이 소정의 패턴을 이루어 배치된 기판(2)의 양측방에는 캐소오드(3)이 대향 설치되어 있고, 이 캐소오드(3)의 상단에는 필라멘트(4)가 가설되어 있다.1 is a cross-sectional view showing the structure of a fluorescent display device according to the present invention, in which cathodes 3 are opposed to both sides of a substrate 2 on which phosphors 1 are arranged in a predetermined pattern. At the upper end of the cathode 3, a filament 4 is installed.

또, 필라멘트(4)와 형광체(1) 사이에는 그리드(5)가 배치되어 있으며 이들 구조체를 둘러싸는 외위기(6)은 대측면에 투명도전막(7)이 증착되어 있다.In addition, a grid 5 is arranged between the filament 4 and the phosphor 1, and the transparent conductive film 7 is deposited on the opposite side of the envelope 6 surrounding these structures.

이와같은 구조는 종래의 형광표시장치와 동일한 것이나, 본 고안에서는 그 외에도 투명도전막(7)의 한끝이 외위기(6)의 외부로 노출되어 전위의 직류 또는 펄스 제너레이터(8)를 개재하여 발생되는 펄스를 인가받을수 있게 되어 있다.Such a structure is the same as that of a conventional fluorescent display device. However, in the present invention, one end of the transparent conductive film 7 is exposed to the outside of the envelope 6 and is generated via a direct current or a pulse generator 8 of potential. The pulse can be applied.

이상과 같은 구성에 의하면 필라멘트(4)가 통전 가열되어 열전자를 방출하기 시작하면, 그리드(5) 측으로 방사되는 열전자는 아무런 영향을 받지 않고 형광체(1)로 충돌되고, 그리드(5)의 반대측으로 방사되는 열전자는 투명도전막(7)에 의해 형성된 전계와 만나 반발하여 그리드(5) 측으로 되반사되어 형광체(1)에 충돌되는 열전자의 양이 많아지게 되는 기존의 효과를 그대로 나타냄과 동시에 본 고안에서는 콘택트 스프링을 생략할수 있어서 부품수를 절감할 수 있고, 이러한 부품 절감에 의해 조립수공도 간편하게 되어 생산성 향상에 기여하는 바도 큰 실용성을 가지고 있다.According to the above configuration, when the filament 4 is energized and heated to emit hot electrons, the hot electrons radiated to the grid 5 side are collided with the phosphor 1 without any influence, and the opposite side to the grid 5 is applied. The radiated hot electrons resemble the electric field formed by the transparent conductive film 7 to reflect back to the grid 5 side and exhibit the existing effect of increasing the amount of hot electrons colliding with the phosphor 1, while in the present invention The contact spring can be omitted, and the number of parts can be reduced, and as a result, such as the reduction of parts, assembling work is simplified, which contributes to productivity improvement.
