본 발명은 유기분산형 전계발광체 및 유기분산형 전계발광램프에 관한 것으로, 제조비용이 적게 들고 수분흡수성이 낮아서 발광성능이 향상되며 수명이 연장되고 접착력이 뛰어난 유기분산형 전계발광램프에 관한 것이다.The present invention relates to an organic dispersion type electroluminescent lamp and an organic dispersion type electroluminescent lamp. The present invention relates to an organic dispersion type electroluminescent lamp having low manufacturing cost and low water absorption, which has improved luminous performance, extended life, and excellent adhesion.

일반적으로, EL램프라고 불리어지는 전계 발광램프(electroluminescent lamp)는 차량의 대시패널, 선박의 조타실의 계기판 등에 장착되어 사용된다.In general, an electroluminescent lamp, called an EL lamp, is used to be mounted on a dash panel of a vehicle, an instrument panel of a steering wheel of a ship, and the like.

전계 발광램프가 발광하는 이론적 배경을 소개하면 다음과 같다.The theoretical background of the electroluminescent lamp emitting light is as follows.

도 1은 EL Plate의 기본 구조를 도시한 사시도이다. 이 도면에 도시된 바와 같이, EL Plate는 다수의 레이어(layer)가 겹쳐져 만들어지는 구조로 되어 있다.1 is a perspective view showing a basic structure of an EL plate. As shown in this figure, the EL plate has a structure in which a plurality of layers are overlapped.

상기한 EL Plate는 총 7개의 레이어로 구성되고, 각 레이어는 보호막(1), 금속전극(2), 절연층(3), 형광층(4), 투명전극(5), 투명기판(6) 및 보호막(7)이 순차적으로 겹쳐지는 구조로 되어 있다.The EL plate is composed of a total of seven layers, each layer of the protective film (1), metal electrode (2), insulating layer (3), fluorescent layer (4), transparent electrode (5), transparent substrate (6) And the protective film 7 sequentially overlap.

그래서, EL Plate에 교류전원이 공급되면, 형광체로 구성된 형광층(4)에 교류전압이 인가되어 형광체 내의 고전계 부분에 의하여 전자가 가속됨으로써, 고에너지 전자가 발생된 들뜬 상태로 되고, 이 상태를 "여기" 상태라고 한다. "여기" 상태는 전계의 방향이 변할 때마다 얻어지기 때문에, 교류전압을 인가하면 한 주기 동안 두번 발광한다. 투명전극(5)과 배면의 금속전극(2) 사이에 전압이 흐르게 되어 임계전압을 넘게되면 절연체와 형광체의 한쪽계면에 존재하는 전자들이 형광체 내부로 터널링(tunnelling)되면서 매우 강한 형광체 내부의 전계로부터 큰 운동에너지를 얻게된다. 이 고에너지전자들은 형광체 내부에 주입된 발광원자와 충돌하여 발광원자의 전자들을 "여기"시키고 "여기"된 전자들이 다시 저 준위로 떨어지면서 빛을 발생시킨다. 충돌 후에 전자들은 다른 쪽 계면에 포획되어 반대 극성의 신호가 인가되면 이미 계면에 포획된 전자들이 다시 형광 내부로 터널링(tunnelling)하면서 빛을 발생시킨다.Therefore, when AC power is supplied to the EL plate, an AC voltage is applied to the fluorescent layer 4 made of phosphors, and electrons are accelerated by the high electric field portion in the phosphors, whereby high energy electrons are generated. Is called the "here" state. Since the "excitation" state is obtained every time the direction of the electric field changes, it emits light twice in one period when an alternating voltage is applied. When a voltage flows between the transparent electrode 5 and the metal electrode 2 on the back surface and exceeds the threshold voltage, electrons existing in one surface of the insulator and the phosphor are tunneled into the phosphor, and thus, from the electric field inside the very strong phosphor. Big kinetic energy. These high-energy electrons collide with light-emitting atoms injected inside the phosphor to "excite" the electrons of the light-emitting atoms and to generate light as the "excited" electrons fall back to the low level. After the collision, the electrons are trapped at the other interface, and when a signal of opposite polarity is applied, electrons already trapped at the interface are tunneled back into the fluorescence to generate light.

EL필름(electroluminescent lamp film)은 220 ㎛ 미만의 초박형평면에 균일한 발광을 할 수 있으며, 기존 광고판의 후렉스는 배면 조명의 전달의 개념이었으나, EL은 자체발광으로 디스플레이의 개념과 발광시트의 역할을 동시에 수행하여 16가지 색상으로 응용력이 뛰어나며, 가볍고 견고하다. 특수 처리된 수지 필름을 사용하여 색의 선명도가 뛰어나며 기존광고판의 광원이 장파장의 광원이라 눈의 피로감이 심하나 단파장의 광원으로 피로감이 없으며 마일드한 빛을 방출해 시각적 효과가 뛰어나다.EL film (electroluminescent lamp film) is able to emit light uniformly in ultra-thin plane of less than 220 ㎛, and FLEX of the existing billboard was the concept of transmitting the back lighting, but EL is self-luminescence and the concept of display and the light emitting sheet Simultaneously, it is excellent in application with 16 colors, light and solid. It is excellent in color clarity by using specially treated resin film, and the light source of the existing billboard is light source of long wavelength, so eyes are tired, but there is no fatigue with short wavelength light source, and it emits mild light and has excellent visual effect.

상기한 바와 같이, EL Plate는 중간에 절연층이 존재하는데 이 절연층은 다음과 같은 물성을 가져야 한다.As described above, the EL plate has an insulating layer in the middle, and the insulating layer should have the following physical properties.

EL 절연층 소재가 가져야 할 특성은, (1) 유전율이 20(25 ℃, 1 kHz) 정도의 매우 큰 값을 나타낼 것, (2) 유기 용제(아세톤, 아세토니트릴)에 대해 투명하게 녹을 것, (3) 점도가 너무 크지 않을 것 - 10% 농도시 50Cps 이하일 것, (4) 흡습성이 적을 것-상대습도 80% 이상에서 평형 습도 2% 이하일 것, (5) 발광층 및 금속전극(102)을 양쪽에 고정시킬 수 있는 접착성을 가질 것, (6) 부피저항(1.0X1012Ω-cm 이상), 파괴전압(104V/cm 이상)이 높을 것 등이다.The characteristics of the EL insulation layer material should be: (1) exhibit a very large dielectric constant of about 20 (25 ° C, 1 kHz), (2) be transparently dissolved in organic solvents (acetone, acetonitrile) (3) Viscosity not too high-50Cps or less at 10% concentration, (4) Low hygroscopicity-equilibrium humidity 2% or less at relative humidity 80% or more, (5) light emitting layer and metal electrode 102 It should have adhesive property that can be fixed on both sides, (6) volume resistance (1.0X10 12 Ω-cm or more), breakdown voltage (10 4 V / cm or more), etc. are high.

현재 EL 소자의 절연층으로 사용되는 물질로는 시아노에틸화 탄수화물들과 2불화수소를 기초로 한 불소계 고무나 수지이다. 이들 재료는 위에서 열거한 대부분의 특성을 만족시키지만 근본적으로 흡습성이 크고, 접착성이 낮아서 제품의 내구성 및 가공성, 그리고 전기적 특성을 저해한다. 또한 이들 절연물질은 국내에서는 생산이 안되며 개발이 매우 저조하여, 국내 EL 제조회사들은 이들 절연물질을 수입에 의존하고 있다. 그러므로, 국내에서 제조되는 EL Plate는 수출시 외국에서 제조된 EL Plate보다 가격이 비싸다는 문제점이 있다.Currently, the material used as the insulating layer of the EL element is a fluorine-based rubber or resin based on cyanoethylated carbohydrates and hydrogen difluoride. These materials satisfy most of the properties listed above, but are fundamentally hygroscopic and low adhesion, which hinders the durability, processability, and electrical properties of the product. In addition, these insulating materials are not produced domestically and are very poorly developed, and domestic EL manufacturers rely on importing these insulating materials. Therefore, there is a problem that the EL plate manufactured in Korea is more expensive than the EL plate manufactured in foreign countries at the time of export.

따라서, 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로, 유전특성이 향상되고, 수분에 대한 내성이 뛰어나며, 가격이 저렴하며 접착력이 뛰어난 유기분산형 전계발광체를 이용한 유기분산형 전계발광램프를 제공하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, and the organic dispersion type electroluminescent lamp using an organic dispersion type electroluminescent lamp having improved dielectric properties, excellent resistance to moisture, low cost and excellent adhesion. It aims to provide.

여기서, 2-cyanoethylacrylate, acrylonitrile 및 methylmethacrylate의 terpolymer는 1 : 1 : 1의 중량비율로 합성되어 만들어지는 것이 바람직하다.Here, it is preferable that the terpolymers of 2-cyanoethylacrylate, acrylonitrile and methylmethacrylate are synthesized at a weight ratio of 1: 1: 1.

이하 첨부도면을 참조로 하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 유기분산형 전계 발광램프를 도시한 사시도이다. 이 도면에 도시된 바와 같이, 본 발명에 따른 유기분산형 전계발광램프는, 종래와 마찬가지로 하부로부터 보호막(101), 금속전극(102), 유전율층(103), 형광층(104), 투명전극(105), 투명기판(106) 및 보호막(101)으로 구성되는 총 7개의 레이어가 순착적으로 겹쳐져 만들어진다.2 is a perspective view showing an organic light emitting electroluminescent lamp according to the present invention. As shown in this figure, the organic dispersion type electroluminescent lamp according to the present invention, as in the prior art, the protective film 101, the metal electrode 102, the dielectric constant layer 103, the fluorescent layer 104, the transparent electrode from the bottom as in the prior art A total of seven layers composed of the 105, the transparent substrate 106, and the protective film 101 are made to overlap each other.

유전율층(103) 및 형광층(104)을 구성하는 베이스판은, 2-cyanoethylacrylate, acrylonitrile 및 methylmethacrylate의 terpolymer가 상호 합성되어, 유전율이 크고 접착력이 뛰어나도록 만들어지게 된다. 그리고, 이들, 2-cyanoethylacrylate, acrylonitrile 및 methylmethacrylate의 terpolymer는 1 : 1 : 1의 중량비율로 합성되어 만들어지게 된다.In the base plate constituting the dielectric constant layer 103 and the fluorescent layer 104, a terpolymer of 2-cyanoethylacrylate, acrylonitrile, and methylmethacrylate is synthesized with each other, so that the dielectric constant is high and the adhesion is excellent. The terpolymers of 2-cyanoethylacrylate, acrylonitrile and methylmethacrylate are synthesized at a weight ratio of 1: 1: 1.

유전율층(103)의 베이스판에는 다수의 유전체, 예를 들어 세라믹(ceramic, 110)이 설치되고, 형광층(104)의 베이스판에는 다수의 세라믹(110)과 다수의 형광체(111)가 각각 설치되어 있다.A plurality of dielectrics, for example, ceramics 110 are provided in the base plate of the dielectric constant layer 103, and a plurality of ceramics 110 and a plurality of phosphors 111 are respectively provided in the base plate of the fluorescent layer 104. It is installed.

유전율층(103) 및 형광층(104)의 베이스판은 유기분산형 절연고분자물질로 만들어져 절연성질을 띠게 된다. 상기한 유기분산형 절연고분자물질은, 2-cyanoethylacrylate, acrylonitrile 및 methylmethacrylate의 terpolymer가 상호 합성되어 만들어지고, 흔히 "CAMP"라고 불리운다. "CAMP"는 종래에 비해 접착력이 뛰어나고 흡습성이 낮다는 것이 실험적으로 증명된다.The base plates of the dielectric constant layer 103 and the fluorescent layer 104 are made of an organic dispersed insulating polymer material to have an insulating property. The above-mentioned organic dispersed insulating polymer material is made by synthesizing a terpolymer of 2-cyanoethylacrylate, acrylonitrile and methylmethacrylate, and is often called "CAMP". "CAMP" is experimentally proved to be superior in adhesive strength and low hygroscopicity compared to the prior art.

흡습성과 유전율은 일반적으로 비례관계를 갖는다. 따라서 유전율을 높이면서도 흡습성을 낮추기 위해서는 하나의 작용기로는 만족시킬 수 없으며, 화학 구조적으로 서로 보완 작용을 할 수 있는 두가지 이상의 작용기를 도입하여야 한다. 즉 강한 소수성기을 나타내는 작용기와 높은 유전율을 나타내는 작용기를 필요로 한다. 기존의 소재에서는 일반적으로 탄수화물을 반복단위로 하는 물질을 사용하기 때문에 수분에 대한 친수성이 매우 크므로 본 발명에서는 탄수화물이 아닌 acrylate계통의 물질을 사용하여 고분자를 합성하였다.Hygroscopicity and permittivity are generally proportional. Therefore, in order to increase the dielectric constant and lower the hygroscopicity, one functional group cannot be satisfied, and two or more functional groups that can complement each other in chemical structure must be introduced. That is, a functional group showing a strong hydrophobic group and a high dielectric constant are required. In a conventional material, since a carbohydrate is generally used as a repeating unit, hydrophilicity is very high, and according to the present invention, a polymer is synthesized using an acrylate-based material rather than a carbohydrate.

EL용 절연고분자인 CAMP(2-cyanoethylacrylate, acrylonitrile 그리고 methylmethacrylate의 terpolymer)의 구성성분 중 2-cyanoethylacrylate와 acrylonitrile은 유전율이 큰 시아노기를 가지고 있으며, methylmethacrylate는 접착력을 증가시키기 위해 사용하였다. 각각의 중량비율이 1 : 1 : 1일 때 EL에 적합한 물성을 나타내었다. 다음은 몇 가지 CAMP의 합성 과정을 설명한 것이다.Among the components of CAMP (2-cyanoethylacrylate, acrylonitrile and methylmethacrylate terpolymer), which is an insulating polymer for EL, 2-cyanoethylacrylate and acrylonitrile have a high dielectric constant cyano group, and methylmethacrylate was used to increase adhesion.

상기한 시료 1, 2, 3, 4, 5 및 6 중에서 5번과 6번은 유기용매에 용해가 안되므로 EL Plate의 제작에 적합하지 못함으로 우리는 시료 5번과 6번을 대상에서 없애기로 하였다. 다음은 시료 1, 2, 3 그리고 4번의 물성 및 물질을 분석한 결과들이다.Of the samples 1, 2, 3, 4, 5 and 6, 5 and 6 are not suitable for the production of EL plates because they are not dissolved in an organic solvent, so we decided to remove samples 5 and 6 from the subject. The following are the results of analyzing the properties and materials of Samples 1, 2, 3 and 4.

4종류의 시료를 분석한 결과 시료 4가 EL plate의 절연체로 가장 적당함을 알았다. 시료 1은 점성이 작아 device 제작이 어려웠다. 그리고 시료 2와 3은 점성이 너무 커서 작업성이 떨어진다.As a result of analyzing four types of samples, it was found that Sample 4 is the most suitable insulator for EL plates. Sample 1 was difficult to produce a device because of its low viscosity. And samples 2 and 3 are too viscous, and workability is inferior.

시료4의 열적 안정성을 알아보기 위해서 DSC를 측정하였다. 그 측정치는 도 3에 도시된 바와 같다.DSC was measured to determine the thermal stability of Sample 4. The measurement is as shown in FIG.

EL Plate 제작후 전기적인 특성조사의 결과는 다음과 같다.The results of the electrical characteristics investigation after EL plate fabrication are as follows.

시료 1은 점성이 없어서 EL Plate의 제작이 어렵기 때문에, 시료 1을 제외한 나머지 시료들로 EL Plate를 제작하여 전기적인 특성을 조사하였다.Since sample 1 is difficult to manufacture an EL plate because it is not viscous, the EL plate was manufactured from the samples except for sample 1, and electrical characteristics thereof were examined.
