A liquid crystal material dispensing apparatus includes a spacer height measuring unit for measuring a height of a spacer on a substrate, and a liquid crystal material dispensing system for determining an amount of the liquid crystal material to be dispensed on the substrate based upon the measured spacer height and for dispensing the liquid crystal material onto the substrate.

Apparatus and method for dispensing liquid crystal material

A liquid crystal dispensing method includes loading a substrate onto a stage, aligning at least one liquid crystal dispenser coupled to a guide bar with a dispensing position on the substrate, dispensing liquid crystal material onto the substrate, and unloading the substrate from the stage.

Liquid crystal dispensing apparatus

A liquid crystal dispensing system includes a frame, a stage coupled to the frame; at least one liquid crystal dispenser moveably coupled the frame over the stage, and at least one measurement member operatively coupled to the liquid crystal dispenser, wherein the at least measurement member detecting an amount of liquid crystal material dispensed from the at least one liquid crystal dispenser.

Liquid crystal dispensing system

A liquid crystal dispensing apparatus includes a needle sheet formed as a unitary piece for dispensing liquid crystal material contained within a liquid crystal container through a nozzle by selectively contacting a needle. The needle sheet includes a needle contacting portion for contacting the needle and a coupling portion for coupling the liquid crystal container to the nozzle. Therefore liquid crystal material is prevented from remaining within the needle sheet and the needle sheet can be easily cleaned.

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.

A liquid crystal dispensing apparatus determines an amount of liquid crystal remaining within a liquid crystal container. The apparatus includes a liquid crystal dispensing unit for containing dispensable liquid crystal, capable of be dispensed directly onto a substrate and a main control unit for determining a total amount of liquid crystal dispensed onto the substrate based on a unitary amount of liquid crystal dispensed and the number of times the unitary amount was dispensed, and determining an amount of liquid crystal remaining by deducting the determined total amount dispensed from an initial amount of liquid crystal contained within the liquid crystal dispensing unit.

A liquid crystal dispensing system includes a liquid crystal material container to contain liquid crystal, the liquid crystal material container provided with a first code corresponding to liquid crystal information; a reading unit to read the recognition code; a discharge pump to draw in and discharge liquid crystal from the liquid crystal material container; and a nozzle to dispense liquid crystal from the discharge pump onto a substrate.

A liquid crystal dispensing apparatus includes a liquid crystal dispensing means and a nozzle cleaning means. The liquid crystal dispensing means includes a liquid crystal container for containing liquid crystal material and a nozzle through which the liquid crystal material may be dispensed on a substrate. The nozzle cleaning means is arranged around the nozzle and removes liquid crystal residue accumulated on a surface of the nozzle, moves to a lower portion of the nozzle to suck and remove the liquid crystal residue after liquid crystal material is dispensed by the liquid crystal dispensing means a predetermined number of times.

Liquid crystal dispensing apparatus with nozzle cleaning device

A liquid crystal dispensing apparatus includes a container to contain liquid crystal, a discharge pump, and a nozzle to dispense liquid crystal from the discharge pump onto a substrate. The discharge pump has a separably formed case, a cylinder received in the case, a piston inserted into the cylinder and having a groove at a lower portion such that the piston draws in and discharges liquid crystal by rotating and moving up-down, and a suction opening and a discharge opening through which liquid crystal is to be respectively drawn in and discharged as the piston is moved.
