Claim 0:
1. A micro light-emitting diode (LED), comprising:
a first semiconductor layer, an active layer, and a second semiconductor layer that are successively stacked together, wherein
the first semiconductor layer and the second semiconductor layer are of different types;
the active layer comprises a first quantum well layer and a second quantum well layer stacked together;
the second quantum well layer and the second semiconductor layer form a nanoring;
the first quantum well layer is configured to emit light of a first color, and the second quantum well layer forming a sidewall of the nanoring is configured to emit light of a second color different from the first color; and
the first semiconductor layer is electrically coupled to a first electrode, and the second semiconductor layer is electrically coupled to a second electrode.
