We demonstrate a series of LCD backlight units with blue LED, green perovskite, and red Cd‐quantum dot or phosphors (Sr[LiAl 3 N 4 ]:Eu 2+ and Mn 4+ activated KSF). The central wavelength of our ultrastable, highly luminescent MAPbBr3 organic‐inorganic perovskite‐polymer film is 530 nm and FWHM ≈18nm. The obtained color gamut is ~90% Rec.2020 without Gaussian fitting.
