Method for repairing broken line, array substrate and active matrix display device

An array substrate, comprising:

• an active area and a bottom peripheral area, a side peripheral area, and a top peripheral area surrounding the active area;
• a data driving circuit, disposed in the bottom peripheral area;
• a plurality of data lines, respectively derived from the data driving circuit and extending to the top peripheral area through the active area, the plurality of data lines comprising at least one broken data line each including a first section and a section disconnected with each other;
• a repair line, derived from the data driving circuit and extending along the side peripheral area and the top peripheral area, and
• a laser welding point, disposed at intersection position between the broken data line and the repair line and located in the top peripheral area, wherein the broken data line is configured to be welded to the repair line through the laser welding point;
• wherein, in the top peripheral area, the repair line is configured to be disconnected near the intersection position to form a repair section derived from the data driving circuit and extending along a first side peripheral area and a part of the top peripheral area to be conductive connected with the second section, and among two disconnected sections of each broken data line, for a first section, signals are introduced from the data driving circuit, and for a second section, signals are introduced from the data driving circuit and the repair section.
