Abstract:
1. An apparatus of dispensing crystal dispensing using ultrasonic wave comprising: a syringe comprising a storage room to store liquid crystal therein; an atomizing/dispensing unit configured to dispense the liquid crystal supplied from the syringe after atomizing the liquid crystal; and a gas supply unit configured to apply a predetermined pressure to the liquid crystal to supply the liquid crystal stored in the storage room of the syringe to the atomizing/dispensing unit, wherein the atomizing/dispensing unit comprises, a case comprising a liquid crystal injecting hole in communication with the syringe; a nozzle body coupled to the case through an exhausting hole of an end from a center along a vertical direction, to connect the liquid crystal injecting hole and the exhausting hole with each other; an ultrasonic wave oscillating unit provided in the nozzle body to oscillate the nozzle both along a vertical direction; and a dispersion preventing part provided under the nozzle body to form a space spaced apart a predetermined distance from the nozzle body, with forming an air-curtain from the exhaustion hole to the substrate to prevent the liquid crystal dispensed on the substrate via the exhaustion hole of the nozzle body from dispersing out of a predetermined region by injecting compressed air via the space.
