Abstract: A liquid crystal dispensing apparatus dispenses liquid crystal onto a substrate. The liquid crystal dispensing apparatus includes a frame, a table, at least one liquid crystal discharge device, and a liquid crystal amount inspecting portion. The table is installed on the frame to have the substrate to be mounted thereon. The liquid crystal discharge device adjustably discharges an amount of liquid crystal, and the liquid crystal amount inspecting portion inspects a liquid crystal dispensing amount by comparing an actual amount of liquid crystal discharged from the liquid crystal discharge device with a preset liquid crystal amount. The liquid crystal discharge device includes a piston to perform ascending motions to draw in the liquid crystal and descending motions to discharge the liquid crystal with an angle of at least a portion of the liquid crystal discharge device determining a magnitude of the ascending/descending motion to control an amount of liquid crystal discharged.

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.
