Patent ID: 8647529

Claim:
A liquid crystal drop apparatus for dropping liquid crystal on a substrate, comprising: a liquid crystal container filled with liquid crystal; a nozzle formed at a lower end of the liquid crystal container for dropping the liquid crystal of the liquid crystal container; a control unit for controlling the nozzle when the nozzle drops the liquid crystal, and an electric field applying unit for applying an electric field to the nozzle, wherein one end of the electric field applying unit directly connected to the nozzle applies an AC electric field to the nozzle, wherein the other end of the electric field applying unit is directly connected to an electrode, which applies an AC voltage from an outside of the liquid crystal drop apparatus to the liquid crystal drop apparatus, such that the AC electric field is generated between the electric field applying unit and the nozzle to uniformly vibrate the nozzle, thereby reducing a size of the liquid crystal drops on the substrate, wherein the nozzle is made of polyethylene and is filled with the liquid crystal, wherein the electric field applying unit adjusts an intensity of the electric field applied to the nozzle directly, wherein the control unit controls the size of the liquid crystal drops by varying the intensity of the electric field, and an intensity of the electric field frequency is generated between the electric field applying unit and the nozzle, and wherein the nozzle is arranged between the liquid crystal container and the electrode, and an extending direction of the nozzle is perpendicular to a surface of the electrode.
