Method of repairing a display panel and a display panel

The present invention discloses a method of repairing a display panel and a display panel, using the common electrode line in the first segment of the display panel and the data line disconnection occurs in the overlapping portion, and a pixel connected to the first segment of a first common electrode is formed so that both ends of the conducting path is disconnected at a data line; and a first data line segments and conducting welding in the overlapping area, the welding at the first two segments the cutting side, is connected to the first common electrode in addition to the first common electrode line segment cut to turn on the data line disconnection occurs. This way the data line repair using the existing display panel, a common electrode line and a common electrode on the data line disconnection repair, repair line may be omitted provided in the display panel, is conducive to narrow frame design, and a display panel without introducing new wiring, so the loss of the data signal can be ignored, in addition, it would not be to limit the number of repair lines and affect the repair data lines.
