This study presents that hybrid-typed Perovskite WLED has higher luminous efficiency (85 lm/W) compared to solid-typed and good wide color gamut performance (123 % of NTSC and 92 % of Rec. 2020). Lower operation temperature and better reliability (over 500 hours) result have also been demonstrated under this design.
