    摘要： Example embodiments are directed to an ink discharge device that discharges uniform amounts of ink droplets from an inkjet head, and a control method thereof. Voltages applied to plural nozzles of the ink-head are changed based on different characteristics of the respective nozzles to discharge uniform amounts of ink droplets from the nozzles. Voltage increments are calculated using a fixed target color value so as to set color value dispersion and voltage increments are calculated using different target color values according to the nozzles so as to satisfy color value differences between the neighboring pixels and thus time required for a DPN process is shortened, and excessive changes of the applied voltages are prevented and thus a preparatory period required to mass-produce an LCD panel is shortened and yield of the LCD panel is increased.

    摘要： A substrate inspecting apparatus to inspect a substrate printed on by a print head to determine whether a printing operation is being accurately performed includes a camera unit to photograph the substrate before the substrate is printed on and to photograph the substrate after the substrate is printed on, and a control part to compare a first image of the substrate before the substrate is printed on with a second image of the substrate after the substrate is printed on through the camera unit and to determine whether the printing operation is being accurately performed on the substrate. Thus, the substrate inspecting apparatus is capable of precisely inspecting the substrate during the printing operation and reducing processing time.
