본 고안은 액정 표시장치의 실험용 셀(Cell)에 관한 것으로서, 더욱 상세하게는 액정 표시장치를 제작할 때 액정의 특성을 미리 조사하도록 하는 액정 표시장치의 실험용 셀에 관한 것이다.The present invention relates to an experimental cell of a liquid crystal display device, and more particularly, to an experimental cell of a liquid crystal display device to investigate the characteristics of the liquid crystal in advance when manufacturing the liquid crystal display device.
일반적으로 액정 표시장치를 제작하는데 있어서, 반드시 실험용 셀을 제작하여 미리 액정의 특성을 조사하게 된다.In general, in manufacturing a liquid crystal display, an experimental cell is necessarily manufactured to investigate characteristics of a liquid crystal in advance.
이때의 실험용 셀은 실제의 액정 표시장치의 셀 보다는 훨씬 작게 만들며, 액정 주입도 진공상태에서 아닌 대기압에서 주입한다.The experimental cell at this time is made much smaller than the actual liquid crystal display cell, and the liquid crystal injection is also injected at atmospheric pressure, not in a vacuum state.
실험적으로 액정의 특성을 조사하기 때문에 셀의 크기가 적을수록 좋으며, 또한 대기압에서 액정을 주입하기 때문에 특별한 기구나 장치 없이도 가능하게 되도록 하였다.Since the characteristics of the liquid crystal are experimentally examined, the smaller the cell size is, the better, and since the liquid crystal is injected at atmospheric pressure, it is possible to make it possible without any special apparatus or device.
제2도는 종래의 액정 표시장치의 실험용 셀을 나타내는 일부절개도로서, 상부기판(1)에 봉인재(4)를 사용하여 하부기판(2)를 부착하고, 봉인재(4)의 양쪽면 중앙부에 액정 주입구(3) (3')를 각각 형성하여 구성되었다.FIG. 2 is a partially cutaway view showing an experimental cell of a conventional liquid crystal display device. The lower substrate 2 is attached to the upper substrate 1 using the sealing material 4, and the central portions of both sides of the sealing material 4 are attached. The liquid crystal injection holes 3 and 3 'were respectively formed in the structure.
이와 같이 구성된 실험용 셀에 액정을 주입하는 방법은, 스포이드와 같은 것에 액정을 묻혀 주입구에 액정방울을 떨어뜨려 주입구 안으로 스며들게 하는 것이다.The method of injecting the liquid crystal into the experimental cell configured as described above is to immerse the liquid crystal in the injection hole by dropping the liquid crystal onto an object such as an eyedropper to penetrate into the injection hole.
이는 진공상태에서 주입하는 것이 아니라 대기압 상태에서 주입하기 때문에 주입구가 양쪽에 있어서 액정이 주입구 안으로 스며들게 된다.This is because it is injected at atmospheric pressure, not at vacuum, so that the liquid crystal is permeated into the injection hole at both sides of the injection hole.
이와 같이 실험용 셀에 액정이 주입되면 편광판을 부착하여 액정의 특성을 파악하게 되므로 액정의 사용을 정확하게 할 수 있도록 하였다.As described above, when the liquid crystal is injected into the experimental cell, the polarizing plate is attached to determine the characteristics of the liquid crystal so that the use of the liquid crystal can be accurately performed.
그러나 스포이드에 액정을 묻혀 실험용 셀의 주입구에 액정을 떨어뜨릴 때, 봉인재 외부에도 액정이 묻어 봉인재 외부를 통해 흐르게 된다.However, when the liquid crystal is buried in the dropper and the liquid crystal is dropped in the inlet of the test cell, the liquid crystal is also buried outside the sealant and flows through the sealant.
봉인재 외부를 통해 흐른 액정의 일부는 아래쪽 주입구까지 도달하여 아래의 주입구를 막게되어 위의 주입구로 스며드는 액정이 셀 내부에 주입되지 못한다.Some of the liquid crystal flowing through the sealant reaches the lower injection hole and blocks the lower injection hole so that liquid crystal penetrating into the upper injection hole is not injected into the cell.
즉, 대기압 상태에서 액정을 주입하게 되므로 한쪽 주입구가 막히게 되면 액정이 주입되지 못하는 문제가 발생하였다.That is, since the liquid crystal is injected at atmospheric pressure, the liquid crystal is not injected when one of the injection holes is blocked.
본 고안은 상기한 바와 같은 종래의 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 액정의 특성을 사전에 조사할 때 사용하는 실험용 셀의 불량을 줄이고자 하는 액정 표시장치의 실험용 셀을 제공하는 데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to test the cell of the liquid crystal display device to reduce the defect of the experimental cell used when the property of the liquid crystal in advance To provide.
상기한 바와 같은 목적을 달성하기 위하여 본 고안은 상부기판과 하부기판이 봉인재로 부착되고, 봉인재의 양쪽면의 중앙부에 주입구가 각각 형성된 액정표시장치의 실험용 셀에 있어서, 상기한 상하부 기판이 겹치는 부분과 봉인재 외부 사이에 보조봉인재를 형성하여 구성되는 액정 표시장치의 실험용 셀을 제공한다.In order to achieve the above object, the present invention provides an upper substrate and a lower substrate with a sealing material, and in an experimental cell of a liquid crystal display device in which injection holes are formed at the centers of both sides of the sealing material, the upper and lower substrates are An experimental cell of a liquid crystal display device is formed by forming an auxiliary sealing material between an overlapping portion and an outside of the sealing material.
이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 액정표시장치의 실험용 셀을 나타낸 일부절개도로서, 제2도에 도시한 내용과 같은 부분에 대해서는 동일부호를 부여한다.FIG. 1 is a partially cutaway view showing an experimental cell of a liquid crystal display of the present invention, and the same reference numerals are given to the same parts as those shown in FIG.
상부기판(1)와 하부기판(2)가 봉인재(4)로 부착되고, 봉인재(4)의 양쪽면의 중앙부에 주입구(3) (3')가 형성되며, 상기한 상하부 기판(1) (2)가 겹치는 부분과 봉인재(4)외부와의 사이에 보조봉인재(5)를 형성하여 구성된다.The upper substrate 1 and the lower substrate 2 are attached to the sealing material 4, and the injection holes 3 and 3 'are formed in the central portions of both sides of the sealing material 4, and the upper and lower substrates 1 The auxiliary sealing material 5 is formed between the part which (2) overlaps, and the sealing material 4 outside.
상기와 같이 형성된 실험용 셀에 액정을 주입하는 방법은 일반적으로 쓰는 방법과 같이 스포이드에 액정을 묻혀 셀의 주입구에 액정을 떨어뜨리면 액정이 스며들게 한다.The method of injecting liquid crystal into the experimental cell formed as described above causes liquid crystal to soak when liquid crystal is buried in the inlet of the cell by buried the liquid crystal in the dropper as in the conventional method.
이때 종래에는 액정이 액정주입실(6) 안으로 주입되고 동시에 일부가 봉인재 외부와 상하부 기판 사이로 스며들던 것이 보조봉인재가 형성되어 있으므로 액정이 스며들지 못하게 된다.In this case, the liquid crystal is conventionally injected into the liquid crystal injection chamber 6, and at the same time, a part of the liquid penetrating between the outside of the sealing material and the upper and lower substrates is formed so that the liquid crystal does not penetrate.
이와 같이 액정이 봉인재 외부와 상하부기판 사이를 따라 아래쪽 주입구로 흘러들지 못하므로 아래쪽 주입구가 막히지 않고, 또 액정주입실(6) 내부에서 발생하던 기포가 제거되어 액정이 원활하게 주입된다.In this way, the liquid crystal does not flow into the lower injection hole along the outside of the sealing material and the upper and lower substrates, so that the lower injection hole is not blocked and bubbles generated in the liquid crystal injection chamber 6 are removed to smoothly inject the liquid crystal.
상기한 바와 같이, 본 고안에 의하면, 실험용 셀에 액정을 주입할 때 자주 발생되는 주입불량을 마지막 봉인재를 형성하여 액정이 원활히 주입되도록 하여 주입불량을 줄일 수 있는 효과가 있다.As described above, according to the present invention, an injection defect frequently generated when injecting a liquid crystal into an experimental cell forms an end sealing material so that the liquid crystal is smoothly injected, thereby reducing the injection defect.
