Patent ID: 8159443

Claim:
A display panel comprising: a plurality of first data lines arranged in parallel; a plurality of second data lines arranged in parallel, alternately configured with the first data lines; a plurality of first scan lines arranged in parallel and interlaced with the first and second data lines; a plurality of second scan lines arranged in parallel, alternately configured with the first scan lines and interlaced with the first and second data lines; a first detecting line coupled to the first data lines for testing the first data lines; a second detecting line coupled to the second data lines for testing the second data lines; a third detecting line coupled to the first scan lines for testing the first scan lines; a fourth detecting line coupled to the second scan lines for testing the second scan lines; a plurality of first electrostatic discharge (ESD) protection circuits, each coupled to one of the first data lines or one of the second data lines; a plurality of second electrostatic discharge (ESD) protection circuits, each coupled to one of the first scan lines or one of the second scan lines; a first common electrode line having a first voltage port, wherein each first data line is coupled to the first common electrode line through the corresponding first ESD protection circuit; a second common electrode line having a second voltage port, wherein each second data line is coupled to the second common electrode line through the corresponding first ESD protection circuit; a third common electrode line having a third voltage port, wherein each first scan line is coupled to the third common electrode line through the corresponding second ESD protection circuit; and a fourth common electrode line having a fourth voltage port, wherein each second scan line is coupled to the fourth common electrode line through the corresponding second ESD protection circuit; wherein the first common electrode line and the second common electrode line are not directly connected to the third common electrode line and the fourth common electrode line, and the first, second, third and fourth common electrode lines are not directly connected to each other.
