Method of fabricating a liquid crystal display comprising apparatus for dispensing sealant material
View Patent ↗Provided is an apparatus for dispensing sealant material including: a disposable syringe in which sealant material is filled; a nozzle member installed at a bottom portion of the syringe, for dispensing the sealant material over a substrate; and a gas supply unit for supplying gas into the syringe to apply pressure to the sealant material in a syringe main body, and dispensing the sealant material.
1. A method of fabricating an LCD, comprising:
providing first and second substrates;
dispensing liquid crystal material on at least one of the first and second substrates;
dispensing a sealant material on at least one of the first and second substrates using a dispenser having a disposable syringe body, a syringe case having a cylindrical shape to contain the disposable syringe body, a cap at an upper portion of the disposable syringe body to introduce a gas within the disposable syringe body, and a nozzle member to dispense the sealant material on at least one of the first and second substrates, the disposable syringe body being transparent and made of a material for blocking an ultraviolet ray and the syringe case having at least one window for observing an amount of the sealant material in the disposable syringe body, the nozzle member having a nozzle through which the sealant material is dispensed and a nozzle fixing unit to which the nozzle is fixed, the nozzle fixing unit separably coupled to the syringe case, and the nozzle is extended from the nozzle fixing unit in a predetermined distance so that the extension direction of the nozzle is perpendicular to the cylindrical axis of the syringe case;
attaching the first and second substrates; and
discarding the used disposable syringe body and replacing the used disposable syringe body with a new syringe body;
wherein said dispensing a sealant material includes:
providing the sealant material to the disposable syringe body;
placing the disposable syringe body in the syringe case, forming a syringe; and
dispensing the sealant material through the nozzle.
2. The method of claim 1 , further comprising controlling an amount of sealant dispensed on the at least one of the first and second substrates by controlling a speed of the syringe relative to the at least one of the first and second substrates.
3. The method of claim 2 , wherein a position of the substrate is fixed and the syringe moves.
4. The method of claim 2 , wherein a position of the syringe is fixed and the substrate moves.
5. The method of claim 2 , wherein a position of the substrate is fixed and the nozzle member moves.
6. The method of claim 2 , wherein a position of the nozzle member is fixed and the substrate moves.
7. The method of claim 2 , wherein said replacing the used disposable syringe body with a new syringe body further includes washing the nozzle member and coupling the washed nozzle member to the syringe case.
