RoHS compliance in China
If a display can be manufactured with Quantum Dot's that contain no amount of "Cadmium" while meeting the "REC 2020" will be a huge advantage..

QMC has the key "BLUE CADMIUM FREE" all three "RGB" are 100% cadmium free at 250 degrees and are exceeding 90% of the "REC 2020".

Quote:It is also worth keeping in mind the use of the phrase “based on the actual industrial development situation” in RoHS 2, Article 17. This points to the fact that the Chinese authorities will consider whether the development of the electrical and electronic products is at a level, in China, where technology makes feasible the use of substitutes for the restricted substances.
Quote:Article 10 Producers of electrical and electronic products, in producing or manufacturing electrical and electronic products,shall not violate any mandatory standards or laws, or standards concerning which administrative laws and regulations require implementation. Also, in fulfilling the requirements of national or industry standards for restricted use of hazardous substances in electrical and electronic products,producers shall adopt materials,technologies, and production techniques that have high resource utilization rates, are easy to recycle and treat, that facilitate environmental protection,and that restrict or phase out the use of hazardous substances in [electrical and electronic] products.

Quote: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
