Description

전기습윤 표시장치의 합착방법{BONDING METHOD FOR ELECTROWETTING DISPLAY DEVICE}TECHNICAL FIELD [0001] The present invention relates to a bonding method for an electrowetting display device,

본 발명은 전기습윤 표시장치에 관한 것으로, 특히, 미스 얼라인을 최소화하여 제품의 신뢰성을 향상시키기 위한 전기습윤 표시장치의 합착방법에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrowetting display device, and more particularly, to a method of attaching an electrowetting display device for minimizing misalignment and improving the reliability of a product.

일반적으로 전기습윱(Electrowetting)이란 전해질인 수성 유동체(aqueous liquid)에 전압을 걸어줌으로써 액체의 표면 장력을 변화시키는 기술이다. 상기 기술은 방수 절연체, 전극, 친수성 액체(aqueous liquid)와 소수성 액체(non-aqueous liquid)로 구성된 1 픽셀의 한정된 공간에서 물에 전압을 가함으로 물의 표면장력을 변화시켜 기름을 자리 이동시켜 반사형 표시장치에 응용된다. Electrowetting is a technique that changes the surface tension of a liquid by applying a voltage to an aqueous aqueous liquid, which is an electrolyte. This technique changes the surface tension of water by applying voltage to water in a limited space of 1 pixel consisting of waterproof insulator, electrode, aqueous liquid and non-aqueous liquid, And is applied to a display device.

동작시, 물과 절연체 각각에 정극성 전압과 부극성 전압을 인가하면 색을 띈 기름이 한쪽으로 이동하고, 반사광을 변화시켜 전체적인 컬러를 조절한다. In operation, when a positive voltage and a negative voltage are applied to water and an insulator, the colored oil moves to one side, and the overall color is adjusted by changing the reflected light.

특히, 필립스사 중앙연구소의 롭 헤이즈 박사(Dr. Rob Hayes)에 의한 전기습윤 표시장치는 백색 기판, 투명 전극, 소수성 절연막, 컬러를 뛴 기름, 물 그리고 물에 전압을 걸어줄 수 있는 금속 전극으로 구성되고, 여러 개의 구성요소들이 패시브 매트릭스(PM) 방식으로 구동된다.In particular, the electrowetting display device by Dr. Rob Hayes of Philips Central Research Laboratories is a metal electrode capable of applying voltage to a white substrate, a transparent electrode, a hydrophobic insulating film, colored oil, water, and water And a plurality of components are driven in a passive matrix (PM) manner.

이러한 전기습윤 표시장치는 전압이 가해지지 않을 경우 상기 기름이 기판 상에 고르게 퍼져 있다가 금속 전극에 전압을 걸어주게 되면 기름이 한쪽으로 치우치게 된다. 이러한 기름은 액정표시장치에서 액정의 스위치 역할을 할 수 있다. In the electrowetting display device, when the voltage is not applied, the oil spreads evenly on the substrate, and when voltage is applied to the metal electrode, the oil is biased to one side. Such oil can serve as a switch of the liquid crystal in the liquid crystal display device.

한편, 전기습윤 표시장치는 상판 및 하판 합착할 때 반드시 수중에서 가압 합착이 이루어진다. 수중에서 합착을 진행하게 되므로 정밀하게 상판 및 하판의 얼라인(Align)이 불가능하고 단위 면적당 균등한 압력을 줄 수 없기 때문에 셀 갭이 불균일해져서 합칙이 제대로 이루어지지 않는 문제가 발생하게 된다. On the other hand, in the electrowetting display device, when the upper plate and the lower plate are cemented, pressure bonding is necessarily performed in water. It is impossible to align the upper and lower plates precisely and can not give an equal pressure per unit area, so that the cell gap becomes uneven and the problem is not properly made.

본 발명은 프레임 기구물을 이용하여 상판 및 하판을 합착함으로써 수중뿐만 아니라 대기 상태에서도 충분히 합착 공정을 진행할 수 있어 미스 얼라인 및 불균일한 셀 갭을 방지할 수 있는 전기습윤 표시장치의 합착 방법을 제공함에 그 목적이 있다. The present invention provides a method of attaching an electrowetting display device capable of preventing misalignment and non-uniform cell gap since the lapping process can be sufficiently carried out underwater as well as in the atmospheric state by attaching the upper plate and the lower plate using a frame structure It has its purpose.

본 발명의 실시예에 따른 전기습윤 표시장치의 합착 방법은 박막트랜지스터와, 화소전극과, 상기 박막트랜지스터와 대응되게 형성된 오일층을 포함한 제1 기판을 준비하는 단계와, 상기 제1 기판과 대향되며 블랙 매트릭스와 컬러필터 및 공통전극을 구비한 제2 기판을 준비하는 단계와, 상기 제2 기판 상에 실재를 디스펜싱 하는 단계와, 상기 오일층이 형성된 제1 기판을 프레임 기구물에 안착하는 단계와, 상기 프레임 기구물에 안착된 제1 기판과 마주보도록 상기 제2 기판을 안착하는 단계와, 상기 제2 기판 상에 무게추를 올려 압력을 가하여 상기 제1 및 제2 기판을 합착하는 단계 및 상기 프레임 기구물 배면에서 UV를 조사하여 상기 실재를 경화시키는 단계를 포함하고, 상기 프레임 기구물은 상기 제1 기판을 수납 및 지지하는 모듈 블록부와, 상기 제2 기판에 압력을 가하는 무게추를 포함한다.A method of attaching an electrowetable display device according to an embodiment of the present invention includes: preparing a first substrate including a thin film transistor, a pixel electrode, and an oil layer formed so as to correspond to the thin film transistor; Comprising the steps of: preparing a second substrate having a black matrix, a color filter and a common electrode; dispensing a substance on the second substrate; placing the first substrate on which the oil layer is formed on the frame structure; Placing the second substrate on the second substrate so as to face the first substrate placed on the frame structure, applying pressure to the second substrate to apply pressure to the first substrate and the second substrate, And irradiating UV light on the back surface of the fixture to cure the fixture, wherein the frame fixture includes a module block portion for receiving and supporting the first substrate, 2 < / RTI > substrate.

본 발명의 실시예에 따른 전기습윤 표시장치의 합착 방법은 하부 기판을 지지하는 모듈 박스와 상부 기판에 압력을 가하는 무게추를 구비한 프레임 기구물을 이용하여 하부 기판 및 상부 기판을 합착함으로써 수중에서 합착 공정을 진행할 때 발생할 수 있는 미스 얼라인 및 불균일한 셀 갭을 방지할 수 있다. A method of attaching an electrowetting display device according to an embodiment of the present invention includes joining a lower substrate and an upper substrate using a frame structure having a module box for supporting a lower substrate and a weight for applying pressure to an upper substrate, It is possible to prevent misalignment and non-uniform cell gap that may occur during the process.

상기 화소전극(120)이 형성된 제1 기판(100)에는 상기 유체층(140)과 서로 혼합될 수 없는 오일층(130)이 형성된다.The first substrate 100 on which the pixel electrode 120 is formed is formed with an oil layer 130 which can not be mixed with the fluid layer 140.

상기 제2 기판(200)에는 블랙 매트릭스(210)와, 컬러필터층(220) 및 투명 전극층(230)이 순차적으로 형성된다. A black matrix 210, a color filter layer 220, and a transparent electrode layer 230 are sequentially formed on the second substrate 200.

상기 제1 및 제2 기판(100, 200) 사이에 위치하는 유체층(140)은 전기전도성을 가진 전해질 용액(Electrolyte)가 적절하며, 용매로는 물을 사용할 수 있다. 상기 오일층(130)은 불투명하게 형성되며 주로 검은색으로 형성되며 전기절연성을 가진다. 상기 유체층(140)과 오일층(130)은 서로 다른 전기전도도 또는 극성을 가진다. The fluid layer 140 positioned between the first and second substrates 100 and 200 may be an electrolyte solution having electrical conductivity and water may be used as the solvent. The oil layer 130 is formed to be opaque and mainly black and has electrical insulation. The fluid layer 140 and the oil layer 130 have different electric conductivities or polarities.

상기 제1 및 제2 기판(100, 200)은 도전볼을 포함한 실(240)을 통해 합착되며 상기 실(240)에 의해 일정한 셀-갭을 유지하게 된다. The first and second substrates 100 and 200 are bonded together through a chamber 240 including a conductive ball, and the chamber 240 maintains a constant cell gap.

상기 박막트랜지스터(TFT)가 턴-오프 상태를 유지하면, 상기 공통전극(230)에 일정 레벨의 공통전극전압(Vcom)이 인가되더라도 상기 화소전극(120)이 플로팅 상태를 유지하므로 상기 화소전극(120)과 공통전극(230) 간에는 어떠한 전위차도 발생되지 않는다. 이에 따라 격벽(132)에 의해 정의되는 영역에 수용된 오일층(130)은 전체적으로 퍼진 상태를 유지하게 된다. When the thin film transistor TFT maintains the turn-off state, the pixel electrode 120 remains in a floating state even if a common electrode voltage Vcom of a certain level is applied to the common electrode 230, 120 and the common electrode 230 are not generated. Accordingly, the oil layer 130 accommodated in the region defined by the partition wall 132 is maintained in a spread state as a whole.

상기 박막트랜지스터(TFT)가 턴-온 되면, 상기 화소전극(120)에는 데이터라인을 통해 전달되는 데이터 전압이 인가되고, 상기 공통전극(230)에는 상기 공통전극 전압(Vcom)이 인가되어 상기 화소전극(120)과 공통전극(230) 간에는 일정 레벨의 전위차가 발생된다. 이에 따라, 격벽(132)에 의해 정의되는 영역에 수용된 오일층(130)은 상기 전위차에 대응하여 뭉쳐진 상태를 유지한다. When the thin film transistor TFT is turned on, a data voltage transmitted through the data line is applied to the pixel electrode 120, and the common electrode voltage Vcom is applied to the common electrode 230, A potential difference of a certain level is generated between the electrode 120 and the common electrode 230. Accordingly, the oil layer 130 accommodated in the region defined by the partition 132 maintains a state of being coagulated corresponding to the potential difference.

이때, 상기 격벽(132)은 상기 화소전극(120)의 가장자리를 둘러싸며 일정 높이로 형성되어 상기 오일층(130)을 영역별로 분리한다. At this time, the barrier ribs 132 surround the edge of the pixel electrode 120 and are formed at a predetermined height to separate the oil layer 130 by regions.
