A Vivid Color LED with an ultra‐narrow emission bandwidth (FWHM ~ 10 nm) has been developed. Using this LED backlight for a conventional TFT LCD, we can achieve 97.8% Rec. 2020 in CIE 1976 color space. The new LED has tuneable emission characteristics, recycles light for improved power efficiency, and leverages existing LED and phosphor manufacturing processes for lower cost, and long lifetime. Widespread application in other displays, and lighting are foreseeable.
