The invention discloses a method for repairing a circuit of an electronic display screen by using an IT0 electrode, which comprises the following steps of: firstly, cutting a protective layer and an isolating layer on a display screen by using a blade, exposing the damaged display screen circuit, grinding, polishing and cleaning residues adhered to glass, putting an IT0 wire at a scraped part, forming a groove in a display screen according to a line repair trend line by using a scraper, attaching the scraper to the IT0 wire to rub back and forth at the damaged line, so that the nanometer indium tin oxide wire generates heat by friction, the IT0 wire is changed into a molten IT0 indium tin oxide film by using the friction heat; and meanwhile, filling the molten IT0 film in the groove by using the scraper, and forming a continuous IT0 electrode to repair the circuit of the electronic display screen. According to the method for repairing the circuit of the electronic display screen through the IT0 electrode, the repairing process is simple, the repairing time is short, the repairing efficiency is high, and the repairing effect is good.
