  • Patent number: 11858264
    Abstract: An apparatus for dispensing droplet may include a droplet discharging member, a stage and a control member. The droplet discharging member may include a plurality of nozzles arranged in a first direction by a constant interval. The stage may receive a substrate including 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. The control member may control the droplet discharging member such that amounts of droplets may be 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.
