Active array substrate for flat panel display

A repair method for an active array substrate of a flat panel display, the active array substrate comprising a substrate having a display area, a plurality of first conductive lines disposed on the substrate, a plurality of second conductive lines disposed on the substrate, crossing and electrically separated from the first conductive lines on the display area, a plurality of first repair lines located on a first area outside the display area, crossing and electrically separated from the second conductive lines, a plurality of second repair lines, located on a second area outside the display area and substantially opposite to the first repair lines, crossing and electrically separated from the second conductive lines, and a plurality of third repair lines located on a third area outside the display area and the third area different from the first area and the second area, each of the third repair lines in electrical connection with one of the first repair lines and one of the second repair lines, wherein the second conductive lines are divided into a plurality of second conductive line groups, and each of the second conductive line groups respectively corresponds to one of the third repair lines, and at least one of the second conductive lines has a breach in the display area, the repair method comprising:

• (A) welding the intersection of the second conductive line having the breach and the first repair line such that the second conductive line having the breach electrically connected to the first repair line;
• and
• (B) welding the intersection of the second conductive line having the breach and the second repair line such that the second conductive line having the breach electrically connected to the second repair line.
