Abstract: An apparatus for fabricating a display panel includes a loading plate on which a fabrication substrate is loaded, a plurality of optical microscopes that captures the fabrication substrate and alignment marks of the fabrication substrate, a gripper driver that aligns the fabrication substrate by adjusting a gap between gripper units and rotating the gripper units; and a substrate alignment controller that calculates an amount of rotation correction for the gripper units based on a deviated angle of the fabrication substrate to supply it to the gripper driver, calculates a gripper gap setting value for adjusting the gap between the gripper units using a residual of the aligned fabrication substrate, and provides the gripper gap setting value to the gripper driver.

Abstract: An ink-jet printing apparatus includes an ink-jet head unit including an ink-jet head, and a control device which controls an ink ejection timing of the ink-jet head and includes a comparator comparing first printing pattern information that is stored and second printing pattern information that is input with each other, a control signal generator generating a first head control signal based on the first printing pattern information when a difference between the first printing pattern information and the second printing pattern information is a reference value or less and generating a second head control signal different from the first head control signal based on the second printing pattern information when the difference between the first printing pattern information and the second printing pattern information exceeds the reference value, and a data output unit providing the first head control signal or the second head control signal to the ink-jet head unit.
