A micro-LED (3r) transfer method and a manufacturing method are disclosed. The micro-LED (3r) transfer method comprises: forming a sacrificial post (4) on a micro-LED (3r) to be picked-up on a carrier substrate (1); bonding the micro-LED (3r) to be picked-up with a pickup substrate (5) via the sacrificial post (4); lifting-off the micro-LED (3r) to be picked-up from the carrier substrate (1); bonding the micro-LED (3r) on the pickup substrate (5) with a receiving substrate (12); and lifting-off the micro-LED (3r) from the pickup substrate (5). A complicated pickup head is not necessary, and the technical solution is relatively simple.
