Abstract: A method and apparatus for arranging heads of an inkjet printer such that ink droplets discharged from respective multiple heads are corrected to zero degrees, X-directional positions of the multiple heads are precisely mechanically arranged, and Y-directional positions of the multiple heads are precisely arranged by software. The inkjet printer head arranging apparatus includes: ink droplet formation units forming ink droplets on a substrate by arranging a plurality of heads in a row and injecting ink to the substrate through the heads; a sensing unit sensing the ink droplets formed on the substrate; a position calculation unit calculating the positions of the sensed ink droplets; a correction value calculation unit calculating position correction values for the heads using the positions of the calculated ink droplets; and a position correction unit correcting the positions of the heads using the calculated position correction values of the heads.

Abstract: A liquid crystal display includes data lines extending in a first direction, gate lines extending in a second direction between a first side and a second side of the liquid crystal display and crossing the data lines, and common voltage lines crossing the data lines and parallel with the gate lines. The gate lines include even gate lines coupled to a gate driver at near the first side and odd gate lines coupled to the gate driver at near the second side. The common voltage lines include even common voltage lines coupled to a common voltage supplier at near the second side and odd common voltage lines coupled to the common voltage supplier at near the first side.
