Abstract
A micro light emitting diode (LED) transferring method includes setting a micro LED transfer substrate and a target substrate to initial positions and transferring a plurality of micro LEDs arranged in a partial region of the micro LED transfer substrate to the target substrate. Once the micro LEDs in the partial region are transferred to the target substrate, the micro LED transfer substrate is rotated and a plurality of micro LEDs, arranged in a remaining region of the micro LED transfer substrate, are then transferred to the target substrate.
