Micro LED display and repair method thereof

A repair method of a micro LED display, the repair method comprising:

• providing a display substrate, wherein the display substrate comprises a substrate, a first circuit layer and a second circuit layer, the substrate comprises a plurality of pixel areas, the first circuit layer and the second circuit layer are arranged in each of the pixel areas, and the second circuit layer in each of the pixel areas is arranged side by side with the first circuit layer;
• forming a first soldering layer on the first circuit layer in each of the pixel areas;
• transferring a plurality of first micro LEDs to the display substrate and bonding the first micro LED to the first circuit layer in each of the pixel areas through the first soldering layer;
• forming a second soldering layer on at least one second micro LED;
• and
• transferring the at least one second micro LED to the display substrate and bonding the second micro LED to the second circuit layer in one of the pixel areas through the second soldering layer, wherein an area in which the first soldering layer is arranged is greater than an area in which the second soldering layer is arranged,
• wherein the first soldering layer and the second soldering layer are respectively disposed on the first circuit layer and the second circuit layer arranged in each of the pixel areas and not overlapped with each other, and after the first micro LED and the second micro LED in the same pixel area are supplied with power, the second micro LED bonded to the second circuit layer of one of the pixel areas through the second soldering layer emits light, and the first micro LED bonded to the first circuit layer in each of the pixel areas through the first soldering layer does not emit light.
