QDot™ LCD SharpGreen Perovskite Film
QDot™ LCD SharpGreen Perovskite Film is the colour enhancement film used in Quantum Dot LCD displays in order to achieve its exceptional wide colour gamut (over 85% of Rec2020 standard) and outstanding brightness. This makes the display images look more lifelike, close to how we perceive images in the real world.
QDot™ LCD SharpGreen Perovskite Film is a polymer composite, with embedded green emitting perovskite quantum dots. The material is RoHS compliant (Restriction of Hazardous Substances Directive) and cadmium free. The film exhibits bright green emissions, centred at 525 nm, high photoluminescent quantum yield (PLQY > 80 %) and narrowband emission (FWHM < 20-25 nm).
The material has high reliability under heat, light and humidity. It retains > 80 % of initial photoluminescence within 1000 hours of exposing by heat (85 °C and blue light 10 mW/cm2) and high relative humidity (90 % RH at 60 °C). It also retains > 60% of exposure to extreme high flux conditions (blue light 150 mW/cm2). This ensures that the displays have long lifespans, lasting longer than 30,000 hours.
