Nanosys keeps popping up in the news, but as late as September 2017
they are still using Cd in their green QD-
"For Samsung, Nanosys has developed quantum dots free of toxic cadmium to comply with the European Union’s Restriction on Hazardous Substances (RoHS). But this approach makes it difficult to meet Rec. 2020, because the blue and the green primaries for Rec. 2020 are very close together. Nanosys has developed Hyperion quantum dots that mix cadmium-free red and cadmium-based green quantum dots into a single film that produces narrower green. The result produces cadmium levels below 100 ppm to meet the RoHS directive." 2017: The Year 4K Ultra HD Entered The Mainstream
Has anyone heard different after CES?
