15 February 2017 Wide color gamut LCDs with narrow green emitting films
Author Affiliations +
We demonstrate a series of ultrastable, highly luminescent CH3NH3PbBr3 (MAPbBr3) green emitting organic-inorganic perovskites (OIP) - polymer composite films achieved by a simple yet general strategy, to be used together with red emitters as down-converters for blue LEDs in display technology. These composite films exhibit high photoluminescence quantum yield (PLQY) of up to 48%, high color purity with FWHM (full width at half maximum) as narrow as 18 nm. When combined with blue LED and CdSe-based quantum dots-polymer films or red phosphors as LCD backlight, we can achieve a relatively wide color gamut in Rec. 2020 color space.
