Patent ID: 8714106

Claim:
A liquid crystal dispensing system, comprising: 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 discharge from the discharge pump onto a substrate; and a control unit configured 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, wherein the control unit compares a differential value between a preset dispensing amount of liquid crystal to be dispensed and a substantial measured dispensing amount dispensed onto the substrate with a first limitation value and a second limitation value, wherein the discharge pump is driven to compensate the preset dispensing amount to be dispensed if the differential value of the preset dispensing amount to be dispensed exceeds the first limitation value and the discharge pump is stopped if the differential value of the measured dispensing amount dispensed onto the substrate exceeds the second limitation value.
