Beschreibung
Zusammenfassung:	A method for repairing an anti-fingerprint coating comprises the steps that a to-be-repaired substrate is provided, the to-be-repaired substrate comprises a base material and the anti-fingerprint coating located on the surface of the base material, the surface, away from the base material, of the anti-fingerprint coating is provided with a damaged area, and the anti-fingerprint coating contains silicon-oxygen bonds; the damaged area is coated with hydrobromic acid firstly, then the damaged area coated with the hydrobromic acid is coated with repairing liquid, the repairing liquid contains an alkoxy silane polymer, and the alkoxy silane polymer contains silicon-oxygen bonds; laser is adopted to irradiate the damaged area, so that hydrobromic acid catalyzes bond breaking of a silicon-oxygen bond in the anti-fingerprint coating and bond breaking of a silicon-oxygen bond in the alkoxy silane polymer under irradiation of the laser, and the silicon-oxygen bond in the anti-fingerprint coating after bond breaking is
