Abstract
A liquid crystal dispensing system includes a container to contain liquid crystal to be dispensed, a discharge pump to receive the liquid crystal from the container and to discharge the liquid crystal, a nozzle to dispense the liquid crystal discharged from the discharge pump onto a substrate, and a control unit to control a dispensing amount of liquid crystal discharged from the discharge pump and to compensate the dispensing amount when the dispensing amount of liquid crystal exceeds a limitation value.
