INSPECTION AND REPAIR METHOD FOR LCD PANEL

摘要

The present invention relates to a method for inspecting and repairing a substrate, wherein the method is for inspecting a defective position through a pattern inspection on the substrate, determining whether or not a short circuit or disconnection is in the defective position through image comparison, and then outputting a signal for restoration corresponding to the short circuit or the disconnection in order to automatically restore a defective area. The method for inspecting and repairing the substrate comprises: an inspecting step of optically inspecting a pattern defect on the substrate, and then transmitting information in which the pattern defect is recorded; a deciphering step of determining whether or not the short circuit or the disconnection is in the pattern defect based on the transmitted information for the pattern defect; and a restoring step of recognizing the short circuit or the disconnection in the pattern defect, and then repairing the pattern defect.
