Description

유기전계발광장치{Organic electroluminescent device}Organic electroluminescent device

본 발명은 유기전계발광장치(organic electroluminescent device)에 관한 것으로서, 상세하게는 냉각구조가 개선된 유기전계발광장치에 관한 것이다.The present invention relates to an organic electroluminescent device, and more particularly, to an organic electroluminescent device having an improved cooling structure.

전계발광소자는 전극사이에 개재된 전계발광물질을 포함하며, 전극상에 소정 전압을 인가하여 전계를 형성함으로써 전계발광물질이 발광하여 소정 화상을 구현한다. 이러한 전계발광소자는 이용되는 전계발광물질에 따라 무기전계발광소자와 유기전계발광소자로 나눌 수 있다. 그 중 무기전자발광소자는 일부 실용화되어 시계의 백라이트로 널리 사용되고 있으며, 유기전자발광소자는 상기 무기전자발광소자에 비하여 휘도 및 효율이 높고 저전압에서 구동이 가능하고 응답속도가 빠르고 다색화가 가능하다는 장점을 가지고 있어서 이에 대한 연구가 보다 활발히 진행되고 있다.The electroluminescent device includes an electroluminescent material interposed between the electrodes, and the electroluminescent material emits light by applying a predetermined voltage on the electrode to form a predetermined image. Such electroluminescent devices may be classified into inorganic electroluminescent devices and organic electroluminescent devices according to electroluminescent materials used. Among them, inorganic electroluminescent devices have been widely used as backlights for watches, and organic electroluminescent devices have higher brightness and efficiency than the inorganic electroluminescent devices, can be driven at low voltages, have fast response speeds, and can be multicolored. Because of this, research is being actively conducted.

도 1은 통상적인 유기전계발광소자의 개략적인 구조를 도시한 단면도이다.1 is a cross-sectional view showing a schematic structure of a conventional organic light emitting display device.

도면을 참조하면, 투명기판(11)위에 애노드전극층(12)이 형성되어 있다. 그리고 이 애노드전극층(12)위에는 홀주입층(hole transport layer)(13), 발광층(emission layer)(14), 전자주입층(electron transport layer)(15) 및 캐소오드전극층(16)이 순차적으로 적층되어 있다. 여기서, 홀주입층(hole transport layer)(13), 발광층(emmission layer)(14), 전자주입층(electron transport layer)(15)은 모두 유기전계발광물질로 이루어지는 유기전계발광물질층이다. 이러한 애노드전극층(12)과 캐소오드전극층(16) 사이에 개재되는 유기전계발광물질층은 유기전계발광물질의 재질에 따라 홀주입층과 전자주입성발광층 또는 홀주입성발광층과 전자주입층 등 그 층구조를 다양하게 형성할 수 있다. Referring to the drawing, the anode electrode layer 12 is formed on the transparent substrate 11. On the anode electrode layer 12, a hole transport layer 13, an emission layer 14, an electron transport layer 15, and a cathode electrode layer 16 are sequentially formed. It is stacked. Here, the hole transport layer 13, the emission layer 14, and the electron transport layer 15 are all organic electroluminescent materials made of organic electroluminescent materials. The organic light emitting material layer interposed between the anode electrode layer 12 and the cathode electrode layer 16 may be a hole injection layer, an electron injection light emitting layer, or a hole injection light emitting layer and an electron injection layer depending on the material of the organic light emitting material. Various structures can be formed.

상술한 바와 같이 구성된 유기전계발광소자에 있어서, 애노드전극층(12)과 캐소오드전극층(16)에 소정 전압을 인가하여 그 사이에 전계를 형성함으로써, 애노드전극층(12)과 캐소오드전극층(16) 사이에 개재된 유기전계발광물질층에 의해 발광이 이루어져서 투명기판(11)을 통하여 소정 화상이 구현된다. 이때, 이러한 유기전계발광소자는 구동시 고온의 상태가 되기 때문에 원활한 구동을 위하여 유기전계발광소자를 냉각시키기 위한 냉각구조가 마련되어야 한다. In the organic electroluminescent device configured as described above, the anode electrode layer 12 and the cathode electrode layer 16 are formed by applying a predetermined voltage to the anode electrode layer 12 and the cathode electrode layer 16 to form an electric field therebetween. The light is emitted by the organic light emitting material layer interposed therebetween so that a predetermined image is realized through the transparent substrate 11. At this time, since the organic light emitting diode is driven at a high temperature during driving, a cooling structure for cooling the organic light emitting diode should be provided for smooth driving.

따라서, 종래의 유기전계발광장치에서는 이러한 냉각구조로서, 유기전계발광소자가 마련된 기판과 결합되어 내부를 밀봉하도록 형성된 쉴드 글래스(shield glass)와, 이 쉴드 글래스에 의해 마련된 공간에 충진된 냉각가스인 질소, 또는 헬륨 가스를 이용하여 유기전계발광소자를 냉각시키고자 하였다. 즉, 유기전계발광소자로부터 발생되는 열이 냉각가스의 대류에 의해 쉴드 글래스로 전달되어 외부와 열교환함으로써, 유기전계발광소자의 냉각을 도모하고자 하였다. 하지만, 이러한 냉각가스를 통하여 이루어지는 열전달은 그 효과가 미미하여 유기전계발광소자의 냉각이 적절하게 이루어지지 못하였다. 따라서, 종래의 유기전계발광장치는 유기전계발광소자의 발광 효율이 나빠져서 구현되는 화상의 신뢰성이 나빠진다는 문제점이 있다. Therefore, in the conventional organic light emitting device, as the cooling structure, a shield glass is formed to seal the inside by being combined with a substrate provided with the organic light emitting element and a cooling gas filled in the space provided by the shield glass. Nitrogen or helium gas was used to cool the organic light emitting device. That is, the heat generated from the organic light emitting diode is transferred to the shield glass by the convection of the cooling gas and heat exchanged with the outside, thereby attempting to cool the organic light emitting diode. However, the heat transfer through the cooling gas has a slight effect, and thus the cooling of the organic light emitting device was not properly performed. Therefore, the conventional organic light emitting device has a problem that the luminous efficiency of the organic light emitting device is worsened, the reliability of the image is poor.

본 발명은 상기와 같은 문제점을 감안하여 창출된 것으로서, 유기전계발광소자의 발광효율이 향상되도록 냉각구조가 개선된 유기전계발광장치를 제공하는데 그 목적이 있다. The present invention has been made in view of the above problems, and an object thereof is to provide an organic electroluminescent device having an improved cooling structure to improve the luminous efficiency of the organic electroluminescent device.

In order to achieve the above object, the present invention provides an organic electroluminescent device comprising: an organic electroluminescent device having a transparent substrate, an anode electrode layer, an organic electroluminescent material layer, and a cathode electrode layer sequentially formed on the transparent substrate; Shield glass is installed on the transparent substrate so as to surround the organic light emitting device to seal the inside, and is filled in a space formed between the transparent substrate and the shield glass to absorb heat generated from the organic light emitting device in the phase transition process. Contains liquid crystal material.

그리고 본 발명에 있어서, 상기 액정물질은, 상전이 온도가 낮고(?), 상전이 시 열흡수율이 높은(?) 액정물질인 것을 특징으로 한다. In the present invention, the liquid crystal material is a liquid crystal material having a low phase transition temperature (?) And a high heat absorption at phase transition (?).

도 2는 본 발명에 따른 유기전계발광장치의 일 실시예를 도시한 단면도이다.2 is a cross-sectional view showing an embodiment of an organic light emitting display device according to the present invention.

도면을 참조하면, 투명기판(21) 상에 유기전계발광소자(22)가 마련된다. 이 유기전계발광소자(22)는 예컨대, 투명기판(21) 상에 순차적으로 형성된 애노드전극층(23), 유기전계발광물질층(24) 및 캐소오드전극층(25)을 구비한다. 그리고, 캐소오드전극층(24) 상에는 보호층(26)이 마련된다. 여기서, 유기전계발광물질층(24)은 애노드전극층(23)과 캐소오드전극층에(25) 소정 전위가 인가하면 발광하도록 유기전계발광물질로 이루어진 예컨대, 홀주입층, 전자주입층, 발광층 등을 포함한다. 그리고, 이러한 유기전계발광물질층(24)은 유기전계발광물질의 재질에 따라 홀주입층과 전자주입성발광층 또는 홀주입성발광층과 전자주입층 등 그 층구조를 다양하게 형성할 수 있다. Referring to the drawings, the organic light emitting diode 22 is provided on the transparent substrate 21. The organic electroluminescent device 22 includes, for example, an anode electrode layer 23, an organic electroluminescent material layer 24, and a cathode electrode layer 25 sequentially formed on the transparent substrate 21. The protective layer 26 is provided on the cathode electrode layer 24. Here, the organic electroluminescent material layer 24 may be formed of, for example, a hole injection layer, an electron injection layer, a light emitting layer, etc. made of an organic electroluminescent material to emit light when a predetermined potential is applied to the anode electrode layer 23 and the cathode electrode layer 25. Include. The organic light emitting material layer 24 may have various layer structures, such as a hole injection layer and an electron injection light emitting layer, or a hole injection light emitting layer and an electron injection layer, depending on the material of the organic light emitting material.

그리고, 상기 투명기판(21) 상에는 유기전계발광소자(22)를 둘러싸서 내부를 밀봉하도록 쉴드 글래스(27)가 설치된다. 이 쉴드 글래스(27)는 유기전계발광소자(22)가 마련된 투명기판(21) 상에 접착되어 투명기판(21)과의 사이에 유기전계발광소자(22)가 위치하는 소정 공간부를 형성한다. In addition, a shield glass 27 is installed on the transparent substrate 21 to surround the organic light emitting diode 22 and seal the inside thereof. The shield glass 27 is bonded onto the transparent substrate 21 on which the organic light emitting element 22 is provided to form a predetermined space in which the organic light emitting element 22 is positioned between the transparent substrate 21 and the transparent substrate 21.

그리고, 유기전계발광소자(22)로부터 발생하는 열을 냉각시키기 위한 액정물질(28)이 상기 투명기판(21)과 쉴드 글래스(27)에 의해 형성된 공간부에 충진된다. 이 액정물질(28)을 투명기판(21)과 쉴드 글래스(27)에 의해 형성된 공간부에 충진시키기 위해서 예컨대, 상기 쉴드 글래스(27)에 소정 유입구(미도시)가 마련되며, 액정물질(28)의 주입이 완료되면 밀봉된다. 여기서, 유기전계발광소자(22)로부터 발생하는 열은 액정물질(28)에 전달되어 액정물질(28)의 상전이 과정에서 흡수됨으로써 유기전계발광소자(22)의 냉각이 이루어진다. 이러한 액정물질(28)은 예컨대, 유기전계발광소자(22)의 구동시 발생하는 열이 액정물질(28)의 상전이 과정에서 흡수될 수 있도록 유기전계발광소자(22)의 구동온도 범위 내에서 그 상전이 온도를 가지는 액정물질이 바람직하다. 그리고, 이러한 액정물질(28)은 상전이 시 열흡수율이 높은 액정물질이 바람직하며, 열흡수율이 약 0.1kJ/mol 이상인 액정물질이 바람직하다.The liquid crystal material 28 for cooling the heat generated from the organic light emitting diode 22 is filled in the space formed by the transparent substrate 21 and the shield glass 27. In order to fill the liquid crystal material 28 in the space formed by the transparent substrate 21 and the shield glass 27, for example, a predetermined inlet (not shown) is provided in the shield glass 27, and the liquid crystal material 28 is provided. When the injection is complete, it is sealed. Here, the heat generated from the organic electroluminescent device 22 is transferred to the liquid crystal material 28 and absorbed in the phase transition process of the liquid crystal material 28, thereby cooling the organic electroluminescent device 22. The liquid crystal material 28 may be, for example, within a driving temperature range of the organic light emitting device 22 such that heat generated when the organic light emitting device 22 is driven may be absorbed in the phase transition process of the liquid crystal material 28. Liquid crystal materials having a phase transition temperature are preferred. The liquid crystal material 28 is preferably a liquid crystal material having a high heat absorption rate at phase transition, and a liquid crystal material having a heat absorption rate of about 0.1 kJ / mol or more is preferable.

상술한 바와 같이 구성된 유기전계발광장치에 있어서, 투명기판(21) 상에 형성된 유기전계발광소자(22)를 이루는 애노드전극층(23)과 캐소오드전극층(15)에 소정 전압을 인가하여 그 사이에 전계를 형성함으로써, 애노드전극층(23)과 캐소오드전극층(25) 사이에 개재된 유기전계발광물질층(25)에 의해 발광이 이루어져서 투명기판(21)을 통하여 소정 화상이 구현된다. 이때, 투명기판(21) 상에 형성된 유기전계발광소자(22)는 구동시 고온 상태가 되어 많은 열방출이 이루어지게 된다. 이러한 유기전계발광소자(22)로부터 발생하는 열은 액정물질(28)을 통하여 쉴드 글래스(27)로 전달되며, 쉴드 글래스(27)는 외부와 열교환을 행하게 된다. 여기서, 액정물질(28)은 유기전계발광소자(22)의 구동온도 범위 내에서 그 상전이 온도를 가지며 상전이 시 열흡수율이 높으므로, 유기전계발광소자(22)로부터 발생하는 열이 액정물질(28)의 상전이 과정에서 흡수됨으로써 유기전계발광소자(22)의 냉각이 이루어진다. In the organic electroluminescent device configured as described above, a predetermined voltage is applied to the anode electrode layer 23 and the cathode electrode layer 15 forming the organic electroluminescent element 22 formed on the transparent substrate 21 therebetween. By forming an electric field, light is emitted by the organic electroluminescent material layer 25 interposed between the anode electrode layer 23 and the cathode electrode layer 25 to implement a predetermined image through the transparent substrate 21. At this time, the organic light emitting diode 22 formed on the transparent substrate 21 becomes a high temperature state during driving, and thus a lot of heat is emitted. Heat generated from the organic light emitting diodes 22 is transferred to the shield glass 27 through the liquid crystal material 28, and the shield glass 27 performs heat exchange with the outside. Here, since the liquid crystal material 28 has a phase transition temperature within the driving temperature range of the organic light emitting element 22 and has a high heat absorption at the time of phase transition, the heat generated from the organic light emitting element 22 is transferred to the liquid crystal material 28. The organic electroluminescent device 22 is cooled by being absorbed in the phase transition process.

본 발명에 따른 유기전계발광장치는 유기전계발광소자가 마련된 투명기판 상에 쉴드 글래스가 설치되며, 이 쉴드 글래스와 투명기판 사이에 형성된 공간부에 액정물질을 충진시킴으로써, 유기전계발광소자로부터 발생하는 열이 액정물질의 상전이 과정에서 흡수되어 유기전계발광소자의 효율적인 냉각이 이루어진다. 따라서, 본 발명에 따른 유기전계발광장치는 유기전계발광소자의 발광효율이 향상되어 구현되는 화상의 신뢰성이 향상된다는 장점이 있다. In the organic electroluminescent device according to the present invention, a shield glass is installed on a transparent substrate on which an organic electroluminescent element is provided. Heat is absorbed in the phase transition process of the liquid crystal material, thereby achieving efficient cooling of the organic light emitting display device. Therefore, the organic light emitting display device according to the present invention has an advantage of improving the light emitting efficiency of the organic light emitting display device, thereby improving the reliability of the image.
