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

摘要

In a method of repairing a display panel, only a defective portion of the display panel is lighted. Heat generated from the lighted defective portion is detected to obtain a position of a defect in the defective portion. A laser is irradiated onto the defective portion to repair the defective portion. The heat generated from the lighted shorted portion is detected using infrared light to obtain an accurate position of the defect in the shorted portion. Thus, an invisible minute defect such as a tiny short can be accurately repaired, so that a yield of the display panel is improved.
