본 고안은 액정 디스플레이 제조시 액정을 주입하는 장치에 관한 것으로서, 보다 구체적으로는 액정통으로부터 액정 디스플레이 셀에 액정을 직접 주입할 수 있는 액정 주입장치에 관한 것이다.The present invention relates to a device for injecting a liquid crystal in the manufacture of a liquid crystal display, and more particularly to a liquid crystal injector capable of injecting a liquid crystal directly from the liquid crystal container to the liquid crystal display cell.
각종의 장치에서 발생하는 전기적인 정보를 시각정보로 변화시켜 인간에게 전달하는 디스플레이 중에서도, 액정 디스플레이는 굴절률, 유전 이방성, 자화율 등에 비교적 큰 이방성을 보이며 갖가지 상태 간 천이를 비교적 저에너지의 외력으로 할 수 있어 저전압, 저전력구동의 표시재료로서 많이 사용되고 있다. 그런데, 상하의 유리기판이 접합된 액정 디스플레이 셀 내의 공간에 액정 주입구를 통해 액정을 주입하기 위해, 종래에는 1 도에 도시된 바와같이, 액정 디스플레이 셀 (10) (이하, 간단히 셀이라 한다) 을 보유하는 셀지지용 카세트 (11) 에 셀을 장착한 상태에서, 챔버 (12) 내에 진공을 형성하고, 액정 보트 (13) 가 액정통 (14) 내로 침지되어 액정을 담은 후 상승하여, 카세트내의 셀의 액정주입구와 접촉된 상태에서, 진공을 해제함으로써 액정 보트 (13) 내의 액정이 액정 주입구를 통해 셀 (10) 내의 공간에 주입된다. 그러나, 상기한 종래의 액정 주입장치를 이용하여 액정을 주입하면, 챔버의 공간에 제약이 있고, 액정 보트가 카세트와 액정 통 사이를 왕복하므로 시간이 많이 걸리고 대량생산에는 부적합하며 액정의 손실을 야기하는 문제점이 있었다.Among displays that convert electrical information generated from various devices into visual information and deliver it to humans, liquid crystal displays show relatively large anisotropy in refractive index, dielectric anisotropy, and susceptibility, and can make transition between various states with relatively low energy external force. It is widely used as a display material for low voltage and low power driving. By the way, in order to inject liquid crystal into the space in the liquid crystal display cell to which the upper and lower glass substrates are bonded, a liquid crystal display cell 10 (hereinafter simply referred to as a cell) is conventionally held as shown in FIG. In the state where the cell is attached to the cell supporting cassette 11, a vacuum is formed in the chamber 12, and the liquid crystal boat 13 is immersed in the liquid crystal cylinder 14 to contain the liquid crystal and then rises, thereby increasing the cell in the cassette. In the state of contact with the liquid crystal injection hole of, the liquid crystal in the liquid crystal boat 13 is injected into the space in the cell 10 through the liquid crystal injection hole by releasing the vacuum. However, when the liquid crystal is injected using the above-mentioned conventional liquid crystal injector, there is a limitation in the space of the chamber, and the liquid crystal boat reciprocates between the cassette and the liquid crystal barrel, which takes a lot of time and is not suitable for mass production and causes liquid crystal loss. There was a problem.
본 고안은 종래의 액정 주입장치의 상기한 바와같은 문제점을 감안하여 안출된 것으로서, 진공챔버를 이용하지 않고 액정 디스플레이 셀에 액정을 직접 공급하여 액정 주입시간을 단축하고 액정의 손실을 방지할 수 있는 액정 주입장치를 제공하는 것을 기술적 과제로 한다.The present invention has been made in view of the above problems of the conventional liquid crystal injection apparatus, and can directly supply the liquid crystal to the liquid crystal display cell without using a vacuum chamber to shorten the liquid crystal injection time and prevent the loss of the liquid crystal. It is a technical problem to provide a liquid crystal injection apparatus.
