Abstract: A method of manufacturing a display apparatus is provided. The method includes forming a test area on a display substrate, irradiating a first laser to the test area and determining relative positions of the test area and a first irradiation area formed by irradiating the first laser to the test area, and correcting a position of a second laser irradiated to the display substrate based on the relative positions of the test area and the first irradiation area.

Abstract: An inkjet printing apparatus includes: an inkjet head including nozzles that discharge an ink; and a controller that controls to discharge the ink by the nozzles. The controller includes: a nozzle coordinate analyzer that analyzes coordinates of the nozzles based on a substrate; a nozzle selection probability grantor that assigns a nozzle selection probability the nozzles that how likely the nozzles are selected to discharge the ink; and an ink discharge determinator that determines whether to discharge the ink or not based on the nozzle selection probability.
