Description
본 발명은 액정표시소자에 전계발광소자 부착 방법에 관한 것으로, 보다 상세하게는 액정표시소자의 백라이트로 사용되는 전계발광소자 일체형 액정표시소자제조방법에 관한 것이다.The present invention relates to a method of attaching an electroluminescent element to a liquid crystal display device, and more particularly, to a method of manufacturing an electroluminescent device-integrated liquid crystal display device used as a backlight of a liquid crystal display device.
액정표시소자는 액체의 유동성과 함께 고체의 결정과 같은 규칙적인 분자배열을 가지면서, 광학적 이방성을 가지고 전압등이 가해지면 전계의 방향을 따라 분자배열이 바뀌는 액정의 성질을 이용하여 도형, 문자 또는 그림을 표시하는 장치를 말하며 평판 디스플레이가 가능하여 브라운관을 대체해 나가는 추세이다.The liquid crystal display has regular molecular arrangements such as solid crystals with fluidity of liquid, and has optical anisotropy and uses the property of liquid crystals in which the molecular arrangement changes along the direction of the electric field when voltage is applied. It is a device that displays pictures, and it is replacing the CRT with a flat panel display.
또한, 경박 단소한 제작이 가능하여 각종 휴대용 전자기기, 즉 휴대용 전화기, 노트 컴퓨터, PDA 등에 주로 사용된다.In addition, it is possible to make light and simple, and is mainly used for various portable electronic devices, that is, a portable telephone, a notebook computer, a PDA, and the like.
상기 액정표시소자는 비발광성소자(수광성소자)이므로 어두운 곳에서는 디스플레이 소자로서의 기능을 상실하게 된다. 이러한 단점을 글복하기 위해 액정 화면을 균일하게 후면 조사하는 광원장치를 필요로 하는 데 이 광원 장치가 백라이트이다.Since the liquid crystal display device is a non-light emitting device (light receiving device), the liquid crystal display device loses its function as a display device in a dark place. In order to overcome these disadvantages, a light source device for illuminating the liquid crystal screen uniformly is required. This light source device is a backlight.
백라이트는 액정표시소자의 투과율에 맞는 휘도 특성 및 휘도 균일성, 경박 단소, 저 소비전력 등 요구성능에 따라 냉음극 형광등, 전계발광소자(EL: Electro Luminescence), LED(Light Emmitting Diode) 등이 널리 쓰인다.The backlight is widely used for cold cathode fluorescent lamps, electroluminescence (EL), and light emitting diodes (LEDs) according to the required characteristics such as luminance characteristics, luminance uniformity, light weight, small power consumption, and low power consumption. Used.
특히 전계발광소자는 면광원으로서 경박단소, 휘도 균일성이 높은 등 액정표시소자의 경량화, 박형화에 가장 유리한 백라이트로 현재 가장 널리 쓰이고 있는 추세이다.In particular, the electroluminescent device is the most widely used backlight as the most favorable backlight for the light weight and thinness of the liquid crystal display device, such as light and small and light uniformity as a surface light source.
EL은 황화아연등 전압을 가하면 형광을 발하는 재료를 이용한 표시소자로서, 투명 전극이 패터닝된 ITO PET상의 투명 전극위에 황화아연등으로 등으로 구성된 발광층을 형성하고 상기 발광층위에 절연층을 형성하며 상기 절연층 위에 알루미늄 전극 기판을 배치하고, 상기 전극 기판 위에 보호 필름을 도포한 구조로 이루어진다.EL is a display device using a material that fluoresces when a zinc sulfide lamp is applied, forming a light emitting layer made of zinc sulfide lamp or the like on a transparent electrode on an ITO PET patterned transparent electrode and forming an insulating layer on the light emitting layer An aluminum electrode substrate is disposed on the layer, and a protective film is coated on the electrode substrate.
투명 전극과 배면 전극기판에 전압을 인가하면 전자가 상기 전극기판사이를 이동하면서 발광입자에 충돌하게 되고, 발광입자는 전자와 충돌하여 자체적으로 발광하게 된다.When voltage is applied to the transparent electrode and the back electrode substrate, electrons move between the electrode substrates and collide with the light emitting particles, and the light emitting particles collide with the electrons to emit light by themselves.
상술한 바와 같이 형성된 전계발광소자를 도 3에서 도시하는 바와 같이 LCD의 후면부에 장착시켜 조립을 하게 된다.The electroluminescent element formed as described above is assembled to the rear portion of the LCD as shown in FIG.
그러나 전계발광소자(2)를 액정표시소자(4)에 조립할 때 단자전극부(6)를 납땜해야 하고 조립 취급시 오염될 가능성이 높은 문제점이 있다.However, when assembling the electroluminescent element 2 to the liquid crystal display element 4, there is a problem in that the terminal electrode portion 6 must be soldered and the contamination may be high during assembly and handling.
