Abstract:
A liquid crystal dispensing apparatus determines an amount of liquid crystal remaining within a liquid crystal container. The apparatus includes a liquid crystal dispensing unit for containing liquid crystal material dispensable onto a substrate, the a liquid crystal dispensing unit including a liquid crystal container for containing the dispensable liquid crystal material and for receiving supplied gas, an upper cap secured to the liquid crystal container, a nozzle arranged at a lower portion of the liquid crystal container through which the liquid crystal material is dispensable, and a valve structure for allowing liquid crystal material contained within the liquid crystal container to enter the nozzle via a pressure from the supplied gas; and a weight measuring unit coupled to the liquid crystal dispensing unit for determining a weight of an amount of liquid crystal material remaining within the liquid crystal dispensing unit, wherein the weight measuring unit installed at the lower surface of the upper cap.
