Yes, I read it. Maybe you should do the same. It says EXACTLY what I said it says. Samsung is Cd-free and Nanosys has developed hyperion. That's all it says. I read the whole article for that matter, and it's quite clear that the author's grasp on the subject is tenuous at best.

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
