概述：液晶面板的单元装配线是将两个玻璃基板(即安装用于液晶显示器的驱动电路的TFT基板和用于显示颜色的CF基板)以在基板之间填充液晶材料的布置安装在一起的工艺。液晶真空灌装系统实现了“滴注法”，即将液晶材料直接滴到其中一个衬底上，然后将另一个衬底与另一个衬底(上面涂有密封剂)对准，并在真空下将其粘合在一起。这样，消除了LCD注入法(即液晶注入法需要较长时间)的弱点，大大缩短了电池工艺的提前期，从而为扩大液晶面板的尺寸开辟了道路。日立工厂技术有限公司正在为继笔记本电脑、显示器和电视之后不断扩大的液晶面板市场提供符合特定世代需求的生产设备。平井一夫安倍正郎石田茂
OVERVIEW: A cell-assembly line for liquid-crystal panels is a process for fitting together two glass substrates (i.e. a TFT substrate mounting the drive circuit for the liquid-crystal display and a CF substrate for displaying colors) in an arrangement that liquid-crystal material is filled between the substrates. A liquid-crystal vacuum filling system accomplishes “dropping method” — namely, a method in which liquid-crystal material is dropped directly onto one of the substrates, which is then aligned with the other substrate (with sealant dispensed on it) and bonded to it under vacuum. In this way, the weak point associated with the LCD injection method (that is, liquid-crystal injection requires a long time) is eliminated and lead time of cell process is significantly shortened, thereby opening up the way to expand the size of liquid-crystal panels. Hitachi Plant Technologies, Ltd. is providing manufacturing equipment with productivity that fits the needs of particular generations in accordance with the expanding market for liquid-crystal panels — which is succeeding lap-top PCs, monitors, and TVs.
