Abstract
A droplet discharging apparatus may include a transfer part moving a substrate including a first target position in a first direction, an inkjet head disposed on the transfer part and discharging a first droplet to the first target position of the substrate, a first camera positioned in a second direction opposite to the first direction of the inkjet head, the first camera acquiring a first image corresponding to the first target position of the substrate, a second camera positioned in the first direction of the inkjet head, the second camera acquiring a second image corresponding to the first target position of the substrate, and an image processor receiving the first image and the second image, and comparing the first image and the second image to inspect a discharge state of the first droplet.
