본 고안은 전계발광 표시장치(Electro Luminescence Display)의 투면전극에 관한 것으로서, 특히 전계발광 표시장치에 관한 것이다.The present invention relates to a transmissive electrode of an electroluminescent display, and more particularly to an electroluminescent display.
일반적으로 전계발광 디스플레이 장치(이하LD로 칭함)는 전계에 의해 발광되는 얇은 고체 발광층을 그 디스플레이수단으로 사용하였기 때문에 가스 방전셀을 가지는 프라즈마방전 디스플레이 장치에 비해 현저히 얇은 두께로 제작사용할 수 있는 장점이 있다.In general, an electroluminescent display device (hereinafter referred to as LD) uses a thin solid light emitting layer that emits light by an electric field as its display means, and thus has an advantage that the electroluminescent display device can be manufactured and used in a significantly thinner thickness compared to a plasma discharge display device having a gas discharge cell. have.
이러한 ELD의 일반적은 구조는 제1도에서 보는 바와 같이 디스플레이창을 구성하는 전면 유리기판(1) 뒤쪽으로 전면전극(2)들과 제1절연층(3), 전계발광층(4), 제2절연층(5),배면전극(6)들을 차례로 배치한 후 방수용실리콘오일(7)을 개입시켜 배면 유리판(8)으로 봉입시켜서 된 구조로 되며, 이러한 ELD에 있어서 전계형성을 위한 상기 전극(2)(6)중 특히 전면 유리기판(1)바로 뒤쪽에 바치되는 전극(2)은 발광층(4)으로부터의 광통과가 용이하도록 투명체로 해주는 것이 필수적이기 때문에 보통 투명전극을 형성한다.As shown in FIG. 1, the general structure of the ELD includes the front electrodes 2, the first insulating layer 3, the electroluminescent layer 4, and the second behind the front glass substrate 1 constituting the display window. After the insulating layer 5 and the rear electrodes 6 are arranged in sequence, the insulating layer 5 is sealed through the waterproof silicon oil 7 to the rear glass plate 8, and in the ELD, the electrode 2 for electric field formation is formed. In particular, the electrode 2 disposed immediately behind the front glass substrate 1 in the 6 may form a transparent electrode because it is essential to make the transparent material to facilitate light transmission from the light emitting layer 4.
그러나, 이와같이 구성된 종래의 투명전극을 사용하여 대형 ELD를 제작함에 있어서는 기존 투명전극(2)의 저항(일반적으로 ρ=2.3×104Ω·cm)이 높아서 전극(2)(6)의 후미부분으로 갈수록 펄스자연형상과 펄스감소현상이 현저히 발생하게 되고, 이는 결국 전극 말단부에 위치한 화소들의 발광지연과 휘도감소의 현상을 초래하여 원하는 화질의 ELD를 얻어내기 어려운 문제점이 있었으며, 또한 이와 같은 현상을 극복하기 위하여 제2도에 도시된 바와같이 유리기판(1)의 이면에 배치되는 투명전극(2)의 주변둘레와 상부에 도전성이 양호한 금속박막(10)을 형성하여 전술한 바와같은 화소들의 발광지연과 휘도감소현상을 방지해 왔으나 ELD의 제조공정중에 전술한 금속박막(10)의 일부가 단락되거나 탈락하는 문제점이 있었다.However, in manufacturing a large-size ELD using the conventional transparent electrode configured as described above, the resistance (generally ρ = 2.3 × 10 4 Ω · cm) of the existing transparent electrode 2 is high, so that the tail portion of the electrodes 2, 6 is high. In addition, the pulse natural shape and the pulse reduction phenomenon are remarkably generated, which leads to the phenomenon of the light emission delay and the luminance reduction of the pixels located at the end of the electrode, which makes it difficult to obtain the ELD of the desired image quality. In order to overcome this problem, as shown in FIG. 2, a conductive metal thin film 10 is formed on the periphery of the transparent electrode 2 disposed on the rear surface of the glass substrate 1 and on the upper portion thereof to emit light of the pixels as described above. Although delay and luminance reduction have been prevented, some of the above-described metal thin films 10 are shorted or dropped during the ELD manufacturing process.
그래서 본 고안은 이러한 종래의 문제점을 감안하여 한출한 것으로, 투면전극과 함께 설치되는 금속박막이 ELD의 제조공정중에 단락되거나 일부가 탈락되지 않도록 하므로써 소망하는 ELD의 화질을 연출할 수 있도록한 전계발광부 표시장치를 제공함에 그 목적이 있다.Therefore, the present invention has been made in view of such a conventional problem, and the electroluminescent part which can produce the desired image quality of ELD by preventing the metal thin film installed with the projection electrode from being shorted or partly dropped during the manufacturing process of the ELD. It is an object to provide a display device.
따라서, 본 고안은 이와같은 목적을 달성하기 위하여, 유리기판상에 투면전극보다도 도전성이 상대적으로 양호한 금속박막을 배치형성하고, 그 상부에 투명전극을 금속박막과 대응토록 형성하거나, 유리기판상에 소정간격을 유지하면서 장홈을 형성한 수 이홈에 금속박막을 설치하고, 그 상부에 투명전극을 형성하여서 된 특징이 있다.Therefore, in order to achieve the above object, the present invention arranges and forms a metal thin film having a relatively higher conductivity than the transmissive electrode on the glass substrate, and forms a transparent electrode on the upper portion thereof to correspond to the metal thin film, or a predetermined interval on the glass substrate. The metal thin film is installed in the male groove in which the long groove is formed, and the transparent electrode is formed thereon.
이하, 본 고안의 일실시예를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 ELD의 요부발췌 측면단면도이고, 제4도는 이에 따른 투명전극이 설치된 부위의 발췌평면도로써 전면 우리기판(1)과 이 유리기판(1) 이면에 배치되는 투명전극(2) 그리고 제1절연층(3),전계발광층(4), 제2절연층(5),배면전극(6)들이 차례로 배치구성된 후 방수용 실리콘 오일(7)을 개입시켜 배면유리판(8)으로 봉입시켜서 된 ELD를 구성함에 있어서, 전면 유리기판(1)의 이면에 소정간격을 두고 적정깊이의 장홈(1′)을 형성하여, 이 장홈(1′)속에, 예를들면 니켈(N1),몰리브렌(Mo),알루미늄(Al),은(Ag)등 전도성이 투명전극(2)보다 상대적으로 양호한 금속박막(10)을 설치한 후, 그 상부에 투명전극(2)을 형성하여서 된 것이다.3 is a side cross-sectional view of an excerpt of the ELD according to the present invention, and FIG. 4 is an excerpted plan view of a portion where a transparent electrode is installed according to the present invention, and a transparent electrode 2 disposed on the front surface of the front substrate 1 and the glass substrate 1. The first insulating layer 3, the electroluminescent layer 4, the second insulating layer 5, and the back electrodes 6 are sequentially arranged and enclosed in the back glass plate 8 through the waterproof silicone oil 7. In constructing the ELD, long grooves 1 'of an appropriate depth are formed on the rear surface of the front glass substrate 1 at predetermined intervals, and nickel (N1), mol, etc. are formed in the long grooves 1'. The metal thin film 10 having better conductivity than the transparent electrode 2 such as Blen (Mo), aluminum (Al), silver (Ag), and the like is formed by forming the transparent electrode 2 on the upper portion thereof.
또한, 바람직하기로는 전술한 전면 유리기판(1)이면에 알루미늄(Al),은(Ag)을 주성분으로 하는 전도성이 탁월한 금속박막(10)을 소정간격 유지토록 설치하고, 이 상부에 투명전극(2)을 형성하여도 무방하다.In addition, preferably, the above-described front glass substrate 1 is provided with a metal thin film 10 having excellent conductivity mainly composed of aluminum (Al) and silver (Ag) so as to maintain a predetermined interval, and the transparent electrode (top 2) may be formed.
이와 같이 구성된 본 고안의 작용 및 효과를 살펴보면, 전면 유리기판(1)의 이면과 투명전극(2)사이에 금속박막(10)을 설치하므로써, 화면 밝기의 저하를 초래하지 않으면서 투명전극(2)의 저항을 크게 감소하도록 하여 펄스지연 및 감소현상을 없애므로 소망하는 화질의 ELD를 얻어낼수 있도록 한 유용한 고안이다.Looking at the operation and effects of the present invention configured as described above, by installing the metal thin film 10 between the back surface of the front glass substrate 1 and the transparent electrode 2, the transparent electrode (2) without causing a decrease in screen brightness It is a useful design to obtain the ELD of the desired image quality by eliminating the pulse delay and the reduction phenomenon by greatly reducing the resistance of).
