Classification: CPC H | IPC H

Claim 0:
1. A manufacturing method for a light-emitting diode (LED), comprising:
providing a substrate, comprising an upper surface, wherein the upper surface is divided into a plurality of zones;
forming a plurality of LED groups formed on the upper surface, wherein:
the plurality of the LED groups is respectively formed on the plurality of zones and each of the plurality of the LED groups comprises a plurality of LEDs;
the plurality of the LED groups comprises a first LED group; and
the plurality of LEDs of the first LED group comprises one or more defective LEDs;

forming a testing circuit on the substrate, electrically connecting the plurality of LEDs in the first LED group to form a parallel circuit or a series-parallel circuit;
testing the first LED group by the testing circuit;
recording a position of the one or more defective LEDs;
providing a target carrier or a module carrier; and
performing one of the following steps by the position of the one or more defective LEDs:
removing the one or more defective LEDs from the substrate, and then transferring the other of the plurality of LEDs in the first LED group to the target carrier or the module carrier;
not transferring the one or more defective LEDs, but transferring the other of the plurality of LEDs in the first LED group to the target carrier or the module carrier; or
transferring the plurality of LEDs to the target carrier or the module carrier and repairing the one or more defective LEDs on the target carrier or the module carrier.
