Method for repairing organic light-emitting diode display apparatus

A method for repairing an OLED display apparatus, comprising: determining positions of foreign particles (13) in a laminated structure (12); removing the foreign particles (13) and a film over the foreign particles (13) to form a groove (21) in the laminated structure (12), an opening of the groove (21) facing an external environment; and forming a repair structure (31) in the groove (21), a refractive index of the repair structure (31) being less than that of the laminated structure (12). A black vacancy caused by the foreign particles is eliminated, the yield of products is improved, and cost waste is avoided.
