Display panel and method for verifying data lines thereon

A display panel, comprising:

• a substrate, wherein a first peripheral circuit zone, a second peripheral circuit zone, and a display area are defined on a first surface of the substrate, and located between the first peripheral circuit zone and the second peripheral circuit zone;
• a display area circuit, located in the display area;
• N data lines, wherein each of the N data lines crosses the display area circuit from the first peripheral circuit zone to the second peripheral circuit zone, and N is a positive integer greater than 1;
• first switches, located in the first peripheral circuit zone, selectively and electrically connect (2k−1)-th data lines of the N data lines to a first data end or a second data end according to a first signal, wherein k is a positive integer and is not greater than N/2;
• second switches, located in the first peripheral circuit zone, selectively and electrically connect 2k-th data lines of the N data lines to the first data end or the second data end according to a second signal;
• third switches, located on the first surface, selectively and electrically connect the 2k-th data lines of the N data lines to (2k+1)-th data lines of the N data lines according to a third signal;
• and
• fourth switches, located in the second peripheral circuit zone, selectively and electrically connect the 2k-th data lines of the N data lines to the (2k−1)-th data lines of the N data lines according to a fourth signal.
