摘要:
The present disclosure provides a method and a device for repairing a metal wire. The method includes: locating a first position on the metal wire to be repaired, the first position being at a first side of a break point on the metal wire to be repaired; and outputting a first laser beam in such a manner as to move from the first position toward the break point and scan a portion of the metal wire between the first position and the break point, so as to fuse the portion of the metal wire and enable fused metal to flow toward the break point to fill the break point. According to the present disclosure, the metal in proximity to the break point on the metal wire to be repaired is fused with the laser beam, and when the metal wire is scanned by moving the laser beam from the first position toward the break point, the fused metal may flow from the first position toward the break point so as to repair the broken metal wire by means of the metal wire itself, without any need to use a dedicated repairing line. As a result, it is applicable to a terminal region of the display panel where no dedicated repairing line exists.

A display panel and a display device comprising a pixel area(A) and a peripheral wiring area, wherein detection switches are arranged between the pixel area(A) and the peripheral wiring area, the detection switches correspond to gate lines(11) and/or data lines(10) of the pixel area(A) one to one, and the detection switches are configured to control connection and disconnection of the pixel area(A) and the peripheral wiring area. In the display panel, it is possible to precisely and quickly detect whether there is a short-circuit or open-circuit defect and the precise position of the defect. It is only required to perform an inching detection on signal lines in a small area during the detection procedure, which saves detection time and improves detection efficiency.
