Patent attributes
The present invention discloses a transferring method, a manufacturing method, a device and an electronics apparatus of micro-LED. The method for transferring micro-LED at wafer level comprises: temporarily bonding micro-LEDs on a laser-transparent original substrate onto a carrier substrate via a first bonding layer; irradiating the original substrate with laser, to lift-off selected micro-LEDs; performing a partial release on the first bonding layer, to transfer the selected micro-LEDs to the carrier substrate; temporarily bonding the micro-LEDs on the carrier substrate onto a transfer head substrate via a second bonding layer; performing a full release on the first bonding layer, to transfer the micro-LEDs to the transfer head substrate; bonding the micro-LEDs on the transfer head substrate onto a receiving substrate; and removing the transfer head substrate by releasing the second bonding layer, to transfer the micro-LEDs to the receiving substrate.
