본 고안은 액정표시장치의 생산공정중의 편광필름을 고정하는 것에 관한 것으로 특히 간편하게 편광필름을 기판에 고정하면서도 편광축 정렬에 따른 광학적특성을 향상시키고 제품수율을 높일 수 있는 편광필름 고정장치에 관한 것이다.The present invention relates to fixing a polarizing film in the production process of the liquid crystal display device, and more particularly to a polarizing film fixing device that can easily fix the polarizing film to the substrate while improving the optical properties according to the alignment of the polarization axis and increase the product yield .
액정표시장치는 제1도에서 보는 바와 같이 정해진 셀갭(cell gap)을 유지하도록 하여 합착된 상, 하 기판(1) 사이에 액정을 주입하고 편광필름(2)을 상기 상, 하기판(1) 양면에 부착한다.As shown in FIG. 1, the liquid crystal display device injects liquid crystal between the upper and lower substrates 1 bonded to each other to maintain a predetermined cell gap, and the polarizing film 2 is attached to the upper and lower substrates 1. Attach to both sides.
두 편광필름(2)의 투과축 방향과 액정의 러빙(rubbing)방향, 셀갭등이 정확히 조절될 경우 첫번째 편광필름을 통과한 빛은 전압이 인가되지 않았을 때는 편광축이 90°회전하고 전압이 인가되었을 때는 편광축이 변하지 않은 상태로 두번째 편광필름에 입사한다.When the transmission axis direction of the two polarizing films 2, the rubbing direction of the liquid crystal, and the cell gap are correctly adjusted, the light passing through the first polarizing film is rotated by 90 ° when no voltage is applied, and the voltage is applied. When the polarization axis is not changed, it is incident on the second polarizing film.
따라서, 두번째 편광필름 축을 첫번째 편광필름 축과 평행하게 놓을 경우에는 전압을 인가하지 않았을 때는 어둡고 전압을 인가했을 때에는 밝게되는 광학적 스위치(optical switch)가 될 수 있다.Therefore, when the second polarizing film axis is placed in parallel with the first polarizing film axis, it may be an optical switch that is dark when no voltage is applied and becomes bright when voltage is applied.
한편, 두번째 편광필름과 첫번째 편광필름 축을 서로 수직하게 놓을 경우에는 전압을 인가하지 않았을 때는 밝고 전압을 인가했을 때는 어두운 광학적 스위치가 될 수 있다.On the other hand, when the second polarizing film and the first polarizing film axis is placed perpendicular to each other when the voltage is not applied to the light may be a dark optical switch when the voltage is applied.
이러한 액정표시장치 생산 공정중의 편광필름(2)의 부착 공정에 있어서, 종래에는 편광필름(2)의 내측면에 접착제(3)를 도포하여 상하판이 합착된 액정표시장치의 상, 하기판(1)의 양면에 부착되었다.In the attaching process of the polarizing film 2 in such a liquid crystal display device production process, the upper and lower substrates of the liquid crystal display device in which the upper and lower plates are conventionally applied by applying the adhesive 3 to the inner surface of the polarizing film 2. It was attached to both sides of 1).
이와 같은 종래의 편광필름의 부착은 접착제(3)를 이용해서 부착하게 되어 다시 고칠 수 없는 관계로 작업자는 부착에 세심한 주의를 요하게 되며 부착시 발생한 오차는 정정될 수가 없으며 오차가 심한 경우 그 액정표시 장치 판넬은 폐기될 수 밖에 없다.Since the conventional polarizing film is attached using the adhesive 3 and cannot be repaired again, the operator needs to be careful about the attaching. The error generated during the attaching cannot be corrected. The device panel can only be discarded.
그러므로, 접착제를 이용한 편광필름 부착은 첫째로 접착제 때문에 수정이 불가능하여 정확한 편광필름 투과축 세팅(setting)이 어렵고, 둘째, 일단 부착한 후에는 편광필름의 투과축 각도가 영구적으로 고정되어 부착각도에 문제가 있는 판넬은 폐기될 수 밖에 없어 전체 수율을 떨어 뜨리는 문제가 있었다.Therefore, the polarizing film attached using the adhesive is firstly impossible to modify due to the adhesive, so that it is difficult to accurately set the transmission axis of the polarizing film. The problematic panels were forced to be discarded, which lowered the overall yield.
본 고안의 목적은 액정표시장치의 광학특성을 향상시키고 제품 수율을 높일 수 있는 편광필름 부착장치를 제공하는데 있다.An object of the present invention is to provide a polarizing film attachment device that can improve the optical characteristics of the liquid crystal display device and increase the product yield.
이와 같은 본 고안의 목적은 일정한 셀갭(cell gap)을 유지하도록 합착된 상, 하기판 사이에 액정을 주입하고 편광필름을 그 위해 고정하는 액정표시장치 제조공정에 있어서 상, 하기판과 그 위에 덮인 편광필름을 사이에 끼워 고정시킬 수 있는 탄성이 있는 클립(clip)을 제공하므로서 달성된다.The purpose of the present invention is to cover the upper and lower substrates and the upper and lower substrates in the process of manufacturing a liquid crystal display device injecting a liquid crystal between the upper and lower substrates bonded to maintain a constant cell gap and fixing the polarizing film therefor. It is achieved by providing an elastic clip that can be fixed to sandwich the polarizing film.
이와 같은 본 고안의 구성을 첨부도면에 의거 설명하면 다음과 같다.Referring to the configuration of the present invention as described in the accompanying drawings as follows.
제2도에서 본 고안의 액정표시장치는 일정한 셀갭을 유지하도록 합착된 상, 하기판(10)과, 그 양면에 덮인 편광필름(20)과 상기 상, 하기판(10)과 그 위에 덮인 편광필름(20)을 사이에 끼워 고정하는 탄성이 있는 클립(30)을 구비하였다.In FIG. 2, the liquid crystal display device of the present invention includes a polarized film 20 covered on both sides of the upper and lower substrates 10 and the upper and lower substrates 10 and the polarized layers covered on the upper and lower substrates 10 and 16 bonded to maintain a constant cell gap. The elastic clip 30 which pinched | interposed and fixed the film 20 was provided.
이와 같은 본 고안의 고정장치는 일정한 셀갭을 유지하도록 합착된 상, 하기판(10)의 사이에 액정을 주입하고 편광필름(20)을 그 위에 덮고 편광축이 맞도록 편광필름(20)을 조정한 후 제2도의 (c)와 같이 편광필름 클립(30)을 제2도의 (a) 및 (b)와 같이 상, 하기판과 그 위에 덮인 편광필름 상에 끼워 고정시킨다.In the fixing device of the present invention, the liquid crystal is injected between the upper and lower substrates 10 bonded together to maintain a constant cell gap, and the polarizing film 20 is adjusted to cover the polarizing film 20 and the polarization axis is aligned. Then, as shown in (c) of FIG. 2, the polarizing film clip 30 is fixed to the upper and lower substrates and the polarizing film covered thereon as shown in (a) and (b) of FIG.
이와 같은 편광필름 클립은 투과축 각도 세팅과 그 각도의 미세 조정이 매우 간단하고 자유롭다.Such a polarizing film clip is very simple and free to set the transmission axis angle and fine adjustment of the angle.
따라서, 편광필름의 부착 공정에서의 수율은 거의 100%까지 올릴 수 있고, 또 편광필름 고정시 편광필름이 미세한 각도 변화에 따른 광학특성(밝기, 색)을 작업자가 눈으로 확인할 수 있으므로 부분적이나마 편광필름 투과축 각도의 최적화가 가능하다.Therefore, the yield in the attaching process of the polarizing film can be raised to almost 100%, and the polarizing film is partially polarized since the operator can check the optical characteristics (brightness, color) according to the minute angle change when the polarizing film is fixed. Optimization of the film transmission axis angle is possible.
