Abstract
Provided herein a device for discharging ink, the device comprising: a nozzle body comprising a chamber for accommodating ink, and a nozzle for discharging the ink to one surface of a target object; an electrode portion attached to or distanced from the nozzle body; a signal generator for applying a voltage to the electrode portion so that electrons may be induced to a liquid surface of the ink and an electrostatic force may be formed, the voltage being lower than a predetermined discharge critical voltage; a nozzle body driver for moving the nozzle body; and a controller for controlling the nozzle body driver to adjust a distance between the nozzle and the one surface of the target object so that an electrostatic force corresponding to the voltage higher than the discharge critical voltage may be formed and thus the ink may be discharged.
