Abstract

본 발명은 기압차를 이용하여 강판 디스플레이의 셀내에 액정을 균일하게 주입시키는 방법에 관한 것으로서, 진공 챔버내에 셀을 넣은 후에 셀의 내부 공간을 진공 상태로 만들어 넣고서 셀 주위의 기압과 셀내의 진공압과의 기압차를 이용하여 셀 내에 균일하게 액정을 주입하는 방법에 관한 것이다. 본 발명은 종래의 경우에 필요하였던 가압판을 사용하지 않았으며, 또한 불필요한 액정의 손실을 줄였고, 이로인하여 제조 공정 시간과 비용을 절감할 수 있다.The present invention relates to a method of uniformly injecting liquid crystal into a cell of a steel sheet display using a pressure difference, and after the cell is placed in a vacuum chamber, the internal space of the cell is made into a vacuum state, and the atmospheric pressure around the cell and the vacuum pressure in the cell The present invention relates to a method of injecting a liquid crystal uniformly into a cell by using a pressure difference between. The present invention does not use the pressure plate required in the conventional case, and also reduces the loss of unnecessary liquid crystal, thereby reducing the manufacturing process time and cost.
