Display panel repair method and display panel

A display panel formed with an active area and a peripheral area, comprising:

• a first substrate;
• and
• a second substrate, cell-assembled with the first substrate;
• wherein the peripheral area comprises a fan-out area, and the fan-out area is located between an edge of the second substrate and an edge of the active area;
• the first substrate is provided with fan-out wirings for connecting the active area and the peripheral area in the fan-out area, the number of the fan-out wirings is multiple, the first substrate is further provided with a plurality of auxiliary lines, and the auxiliary lines are arranged in one-to-one correspondence with the fan-out wirings;
• and
• each of the auxiliary lines comprises at least one opening portion protruding outward, the auxiliary line at the opening portion does not overlap with the corresponding fan-out wiring, and two ends of at least one of the auxiliary lines are respectively conducted with the two ends of the corresponding fan-out wiring.

• the display panel repair method comprises steps of:
• detecting whether the fan-out wirings are normal;
• when at least one of the fan-out wirings is open-circuited, respectively connecting a second initiating terminal and a second destination terminal of the auxiliary line with a first initiating terminal and a first destination terminal of the corresponding fan-out wiring;
• and
• when at least two of the fan-out wirings are short-circuited, disconnecting the fan-out wiring corresponding to the opening portion of the auxiliary line, and respectively connecting the second initiating terminal and the second destination terminal of the auxiliary line with the first initiating terminal and the first destination terminal of the fan-out wiring.
