Method for repairing a display substrate

A method for repairing a display substrate, wherein

• the display substrate comprises a plurality of thin film transistors disposed on a substrate, each of at least part of the plurality of thin film transistors comprises:
• an active region,
• a gate insulating layer disposed on a side of the active region, and
• a gate disposed on a side of the gate insulating layer distal to the active region,
• wherein the active region comprises a first electrode contact region at one end of the active region, a second electrode contact region at the other end of the active region opposite to the first electrode contact region, and a plurality of connection regions between the first electrode contact region and the second electrode contact region, and each of the plurality of connection regions is coupled to the first electrode contact region and the second electrode contact region, and every two adjacent connection regions of the plurality of connection regions are provided with an opening therebetween, and are spaced apart from each other by the opening, and
• the method comprises:
• locating, in the at least part of the plurality of thin film transistors in the display substrate, a thin film transistor of which the gate and at least one of the plurality of connection regions are short-circuited, and
• disconnecting the at least one of the plurality connection regions of the thin film transistor from the first contact region and the second contact region of the thin film transistor.
