Abstract
A device for printing a droplet onto a substrate includes: a droplet generating member which is needle-shaped and comprises a receiving portion disposed vertically to receive a solution, and a discharge hole connected to the receiving portion and formed on a bottom of the receiving portion so that the solution can be discharged from the receiving portion; a substrate disposed below the droplet generating member, the substrate includes a target portion to which the droplet discharged from the discharge hole of the droplet generating member is dropped and attached; a voltage applier applying a voltage to the droplet so that the droplet can be dropped onto the target portion of the substrate; a volume measuring unit measuring the volume of the droplet; and a droplet control unit maintaining the volume of the droplet at a predetermined level based on the measured volume of the droplet.
