1. An apparatus for dispensing droplet comprising:
a droplet discharging member including a plurality of nozzles arranged in a first direction by a constant interval;
a stage for receiving a substrate thereon wherein the substrate includes a plurality of regions for forming a plurality of pixels of a same size disposed in the first direction and a second direction substantially perpendicular to the first direction; and
a control member for controlling the droplet discharging member such that amounts of droplets are substantially identical in the regions of the substrate for the pixels if the numbers of the nozzles of the droplet discharging member with respect to sides of the regions of the substrate for the pixels are different in the first direction,
wherein the control member identifies patterns of discharged droplets in the regions of the substrate for the pixels and adjusts the amounts of the droplets from the nozzles of the droplet discharging member based on a minimum amount of the discharged droplets in the regions of the substrate for the pixels by controlling operation of each of nozzles of the droplet discharging member such that the amounts of the droplets are substantially identical in the regions of the substrate for the pixels, and
wherein the control member controls the droplet discharging member such that the amounts of the droplets are substantially identical in the regions of the substrate for the pixels if the patterns of the discharged droplets in the regions of the substrate are substantially different.
