QDot™ LCD SharpGreen Perovskite Film is the colour enhancement film that allows LCD displays to achieve an exceptionally wide colour gamut (over 85% of Rec2020 standard) and outstanding brightness. This makes display images look more lifelike, close to the way that out eyes perceive images in the real world. QDot™ LCD Film is a polymer composite with embedded, green emitting perovskite quantum dots. The material is RoHS compliant and cadmium free. The film exhibits bright green emission centred at 525 nm, high photoluminescent quantum yield (PLQY > 80 %) and narrowband emission (FWHM < 20-25 nm) all of which make it a better quality alternative to the current CdSe or InP QDs.
