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 apparatus and a method of controlling a liquid crystal dropping amount are provided to drop liquid crystal onto a substrate corresponding to at least one unit panel area. In one aspect, the apparatus uses a liquid crystal dispensing unit to dispense liquid crystal. The liquid crystal dispensing unit includes a nozzle having a discharging hole through which the liquid crystal is dropped onto the substrate, a needle moveable between a down position in which the needle blocks the discharging hole and an up position in which the needle is separated from the discharging hole, a spring member to bias the needle toward the down position, and a solenoid coil to provide a magnetic force to move the needle to the up position. The dropping amount liquid crystal dispensing unit may be electrically controlled by controlling the solenoid coil or by controlling a gas pressure used to drive the liquid crystal through the discharging hole. Variations and errors in the dropping amount may also be compensated by an automated compensation of the electric power to the solenoid and/or the gas pressure.

Abstract: A liquid crystal dispensing apparatus dispenses liquid crystal onto a substrate. The apparatus includes a liquid crystal container and a nozzle. The liquid crystal container contains the liquid crystal to be dispensed onto the substrate, and the nozzle is disposed on a lower portion of the liquid crystal container. The nozzle has a main body portion, a discharging portion that projects from a lower surface of the main body portion to dispense liquid crystal, and a protecting portion that projects from the lower surface of the main body portion to protect the dispensing portion. The protecting portion projects from the lower surface of the main body portion at least as much as the discharging portion.
