METHOD OF REPAIRING A DISPLAY PANEL AND APPARATUS FOR PERFORMING THE SAME

摘要

PURPOSE: A method for repairing a display panel and an apparatus for performing the same are provided to accurately detect the position of a short circuit by using infrared rays. CONSTITUTION: The defect site of a display panel is flickering(ST240). The heat generated from the defect site is detected(ST260). The position of the defect is determined. Laser is irradiated on the defect site to repair the defect(ST280).
