Realizing　full　color　GaN-based　micro-　and　nano-light-emitting　diode　(nLED)　displays　with　quantum　dots　(QDs)　being　the　color　conversion　media　remains　challenging　because　of　the　limited　QD　color　conversion　efficiency　(CCE).　In　this　article,　by　using　GaN-based　nanorod　LED　as　the　light　source　and　exciting　the　QDs　by　nonradiative　energy　transfer　(NRET)　method,　a　nanorod　LED　with　ultrahigh　CCE　has　been　realized.　At　the　same　time,　a　single　electrical　contact　alternating　current　(ac)-driven　electroluminescence　(EL)　method　is　adopted　to　investigate　the　relationship　between　frequency　and　nLED　performance.　Different　from　the　double　terminal　injection　mode,　on　the　premise　of　lighting　up　the　nanorod　LED,　the　ac-driven　can　also　avoid　the　necessity　of　external　p-type　and　n-type　electrodes,　thus　simplified　the　manufacturing　process　of　LED.　The　final　optical　measurement　shows　that　the　CCE　of　this　hybrid　color　conversion　nLED　driven　by　single　contact　electrode　can　reach　up　to　86.67%　under　the　ac　voltage　of　60　V　and　an　ac　frequency　of　14.2　MHz,　which　shows　that　the　energy　utilization　efficiency　can　be　effectively　improved　by　NRET.　©　1963-2012　IEEE.
