Abstract
A liquid crystal dispensing system includes a container for containing liquid crystal; a liquid crystal measuring sensor proximate the container; a discharge pump for pumping liquid crystal from the container, and a nozzle for dispensing liquid crystal discharged from the discharge pump onto a substrate. In an exemplary embodiment, the crystal dispensing system includes a control unit for controlling a discharge amount of liquid crystal discharged from the discharge pump and calculating and compensating a dispensing amount of liquid crystal based on an amount of measured liquid crystal in the container.
