In　order　to　improve　high　efficiency　for　light-color　conversion,　this　paper　studies　a　high-efficiency　light　recycled　structure　for　quantum　dot　color　conversion　(QDCC)　based　on　a　distributed　Bragg　reflector　(DBR).　The　difference　of　optical　performance　is　discussed　between　the　QDCC　structure　employing　a　DBR　and　an　absorptive　color　filter　(ACF).　Traditional　quantum　dot　color　conversion　layer　(QDCCL)　has　inherent　limitations　of　blue　light　leakage　and　low　light　utilization　rate.　To　solve　this,　an　optical　structure　of　QDCCL　is　proposed　and　discussed　in　detail,　which　uses　a　DBR　instead　of　the　traditional　color　filter　and　realizes　efficient　light-color　conversion.　Different　structures　are　compared　via　experimental　preparation　and　measurement,　such　as　light-emitting　intensity,　color　gamut,　and　light　utilization　rate.　Results　show　that　the　structure　of　QDCCL　combining　a　DBR　can　not　only　achieve　a　high　color　gamut　of　124　NTSC%,　but　also　increase　the　light　utilization　rate　over　twice　than　the　traditional　ACF　structure.　More　importantly,　the　light　emission　intensity　of　red　and　green　sub-pixels　is　increased　by　2.2　and　2.3　times,　respectively.　In　general,　the　structure　proposed　in　this　paper　is　of　great　significance　to　the　development　of　the　display　industry.　©　2021　COPYRIGHT　SPIE.
