이와같이 구성된 전장발광소자의 동작은 다음과 같다.The operation of the EL device configured as described above is as follows.
전극기판(1)과 투명전극(4)에 교류전압이 인가되면 발광층(3)에서 광이 방출되어 투명전극(4)과 방습필름(5)을 통과하여 디스플레이 된다.When an alternating voltage is applied to the electrode substrate 1 and the transparent electrode 4, light is emitted from the light emitting layer 3 and displayed through the transparent electrode 4 and the moisture proof film 5.
그러나, 상기한 바와 같이 형광체 전면이 발광하게 되고, 또한 패턴을 가지도록 발광시키기 위해서는 투명전극이나 알루미늄전극에 패턴을 형성해야 하는 문제점이 있다.However, as described above, the entire surface of the phosphor emits light, and in order to emit light having a pattern, there is a problem in that a pattern must be formed on the transparent electrode or the aluminum electrode.
본 고안은 상기한 바와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 투명전극 이면에 염료층로 된 패턴을 인쇄함으로써 고정된 표시패턴을 표시할 수 있는 전장 발광소자를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a full length light emitting device capable of displaying a fixed display pattern by printing a pattern of a dye layer on the back of the transparent electrode It is.
상기한 바와 같은 목적을 달성하기 위하여 본 고안은, 알루미늄 전극 기판상에 절연층, 발광층이 순차적으로 형성되고, 그 위에 투명전극이 설치되며, 상기와 같이 형성된 기판을 방습필름으로 밀봉하여 형성된 전장 발광소자에 있어서, 상기한 투명전극의 표면상에 염료층패턴을 인쇄하여 형성된 전장 발광소자를 제공한다.In order to achieve the above object, the present invention, the insulating layer, the light emitting layer is sequentially formed on the aluminum electrode substrate, a transparent electrode is installed thereon, the electric field emission formed by sealing the substrate formed as described above with a moisture-proof film In the device, there is provided an electric light emitting device formed by printing a dye layer pattern on the surface of the transparent electrode.
이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 관련된 전장 발광소자의 단면도를 나타낸 것이다.1 is a cross-sectional view of the electric field light emitting device according to the present invention.
전극기판(1)상에 BaTiO3등의 고유전물질을 이용한 절연층(2)을 도포한 후 건조시킨 다음, 이 위에 구리, 알루미늄등이 도핑된 황화아연계 형광체와 고유전율을 갖는 시아노 에칠계 화합물을 혼합한 발광층(3)을 다시 도포한다.After coating the insulating layer (2) using a high dielectric material such as BaTiO 3 on the electrode substrate (1), and then dried, and then on the zinc sulfide phosphor doped with copper, aluminum, etc. The light emitting layer 3 which mixed the lactating compound is apply | coated again.
상기와 같이 전극기판(1)위에 도포된 발광층(3)의 상면으로 투명전극(4)을 적층 또는 열압착 프레스하여 함께 접착시킨 다음, 투명전극(4)의 표면에 소정패턴을 이루도록 염료층(6)을 인쇄하여 놓고, 그 외주를 방습필름(5)으로 밀봉한다.As described above, the transparent electrodes 4 are laminated or thermocompressed pressed onto the upper surface of the light emitting layer 3 coated on the electrode substrate 1 and bonded together, and then a dye layer is formed on the surface of the transparent electrode 4 to form a predetermined pattern. 6) is printed and the outer periphery is sealed with a moisture proof film (5).
이와같이 제조된 전장 발광소자의 전극기판(1)과 투명전극(4) 사이로 교류전압이 인가되면 발광층(3)의 경계면에 몰려 있는 전자들이 가속되어 발광층(3) 내의 원자를 여기시켜 광을 발광하게 된다.When an AC voltage is applied between the electrode substrate 1 and the transparent electrode 4 of the electric light emitting device manufactured as described above, electrons gathered at the interface of the light emitting layer 3 are accelerated to excite atoms in the light emitting layer 3 to emit light. do.
상기한 발광층(3)에서 방출된 광은 투명전극(4), 염료층 패턴(6) 및 방습필름(5)을 투과함으로써 염료층 패턴이 있는 부분과 없는 부분의 색이 다르게 되므로 외부로 조명되는 부분은 소정의 패턴을 표시하게 된다.The light emitted from the light emitting layer 3 passes through the transparent electrode 4, the dye layer pattern 6, and the moisture proof film 5, so that the color of the portion having the dye layer pattern is different from that of the portion having the dye layer pattern is illuminated outside. The portion will display a predetermined pattern.
상술한 염료층(6)는 불투명염료층나 형광염료층 등을 사용할 수 있으며, 형광염료층 사용시는 발광층(3)에서 방출된 광이 염료층에 흡수되어 장파장의 빛을 방출하게 되므로 염료층의 종류와 두께에 따라 색이 변화한다.As the dye layer 6, an opaque dye layer, a fluorescent dye layer, or the like may be used. When the fluorescent dye layer is used, the light emitted from the light emitting layer 3 is absorbed by the dye layer and emits light having a long wavelength. The color changes with the thickness.
즉, 발광층(3)에서 청녹색형광체를 사용하고, 염료층(6)을 적색염료로 하였을 경우는 청녹색바탕에 백색패턴이 표시되는 백라이트를 얻을 수 있다.That is, when the blue layer is used in the light emitting layer 3 and the dye layer 6 is a red dye, a backlight in which a white pattern is displayed on the blue green background can be obtained.
상기한 바와 같이 본 고안에 의하면, 투명전극의 표면에 염료층패턴을 인쇄함으로써 디스플레이되는 조명부분이 일정의 패턴을 가지도록 하여 다색을 표시할 수 있기 때문에 투명전극 필름이나 전극기판층에 패턴을 형성하는 방법보다 한층 간단하게 실시할 수 있는 실용성을 가지고 있다.According to the present invention as described above, by printing a dye layer pattern on the surface of the transparent electrode to display a multi-colored by having a predetermined pattern to display the illumination portion to form a pattern on the transparent electrode film or electrode substrate layer It has practicality which can be performed more simply than the method to do it.
