Abstract
We present a novel quantum dot enhancement film (QDEF) with a remarkable RGB color gamut of over 100.4% (134.2%) of the Rec. 2020 standard (NTSC standard), respectively for a high-resolution liquid-crystal display (LCD). Our efficient QDEF was fabricated by using a highly transparent resin incorporated with high photoluminesce-quantum yield (PL-QY) and narrow full width at half maximum CsPbBr1I2 QDs (Pr-QDs) and CdSe/ZnS QDs (Cd-QDs). The proposed PrCd-QDEF in a LCD with color filters rendered a blue photoluminesce (PL) peak at 452 nm with a FWHM of 20.4 nm, a green PL peak at 530.1 nm with a FWHM of 23.8 nm, and a red color peak at 652.4 nm with a FWHM of 28.1 nm. Moreover, The PrCd-QDEF did not show any cross-talk between the RGB PL colors. Such promising optical results, along with the simple and cost-effective preparation technique, might encourage the manufacture of super high resolution LCDs using a PrCd-QDEF.
