1. A method of transferring a plurality of micro-LED clusters from a substrate to a display panel, the method comprising:
positioning the substrate in a first position such that a first micro-LED cluster of the plurality of micro-LED clusters is aligned with a first cluster of electrical connectors disposed on the display panel, each of the plurality of micro-LED clusters includes at least two micro-LEDs;
moving the substrate toward the display panel such that the first micro-LED cluster of the plurality of micro-LED clusters contacts the first cluster of electrical connectors;
releasing the first micro-LED cluster of the plurality of micro-LED clusters from the substrate;
moving the substrate from the first position to a second position with respect to the display panel, the second position being different from the first position; and
moving the substrate from the second position toward the display panel such that a second micro-LED cluster of the plurality of micro-LED clusters contacts a second cluster of electrical connectors.
