    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, a discharge pump, a nozzle, and a control unit. The discharge pump draws in and discharges liquid crystal that is contained in the container. The nozzle dispenses the liquid crystal discharged from the discharge pump onto a substrate. The control unit determines a dispensing amount of liquid crystal based on a spacer height formed at the substrate and to control the discharge pump in order to dispense the determined amount of liquid crystal onto the substrate.
