Micro-LED transfer method, manufacturing method and device
Abstract:
A micro-LED transfer method, manufacturing method and device are provided. The micro-LED transfer method comprises: obtaining a laser-transparent carrier substrate having a first surface and a second surface with micro-LEDs; forming a protection layer on at least one of the first surface and the second surface and a third surface of a receiving substrate, wherein the third surface is to receive the micro-LEDs to be transferred via pads; bringing the micro-LEDs to be transferred into contact with the pads on the third surface; and irradiating the micro-LEDs to be transferred with laser from the first surface to lift-off the micro-LEDs to be transferred from the carrier substrate wherein the protection layer configured to protect the third surface from the irradiation of the laser.
