Patent ID: 8499428

Claim:
A method of repairing an array substrate of a display panel, comprising: providing an array substrate, the array substrate comprising: a substrate; a first patterned conducting layer disposed on the substrate, the first patterned conducting layer comprising a plurality of gate lines; a second patterned conducting layer disposed on the substrate, the second patterned conducting layer comprising a plurality of data lines and a plurality of common lines, wherein the data lines intersect the gate lines to define a plurality of pixel areas, the data lines comprise a first data lines, the common lines comprise a first common line, the pixel areas comprise a first pixel area, a second pixel area and a third pixel area, the first pixel area, the second pixel area and the third pixel area are disposed on a same side of the first data line, the first pixel area is disposed between the second pixel area and the third pixel area, the first common line penetrates through the first pixel area, the second pixel area and the third pixel area, and the first data line has a broken line defect located on a side of the first pixel area; and a plurality of repairing segments disposed in each of the pixel areas; performing a cutting process to form a first cutting part on the first common line in the second pixel area, and to form a second cutting part on the first common line in the third pixel area, so that a floating common repairing segment is formed between the first cutting part and the second cutting part; and performing a connecting process to electrically connect the repairing segment of the second pixel area, the first data line and the common repairing segment, and to electrically connect the repairing segment of the third pixel area, the first data line and the common repairing segment, so that the common repairing segment is served as a substitution line of the first data line.
