LONDON—Nanoco Group plc (Manchester, England), a specialist in heavy metal free quantum dots, has spoken out against a report that has recommended allowing the continued use of cadmium-selenide in quantum dots in TVs and displays sold in Europe.

Cadmium is a highly toxic and carcinogenic industrial and environmental pollutant, the use of which is therefore highly regulated.

The report was prepared by the Öko Institute eV (Freiburg, Germany) at the request of the Directorate-General for Environment (DG Environment) of the European Commission and has recommended a three-year extension of an exemption as part of the Restriction of certain Hazardous Substances (RoHS) Directive. The same Öko Institute report recommended ending the exemption allowing the use of cadmium in LED lighting.

The report was called for when the European Parliament voted in 2015 by 618 to 33 against the continuation of this cadmium exemption opposing an exemption proposed by the European Commission. The Öko Institute had previously recommended an exemption for cadmium in quantum dots arguing that alternatives were not ready. This time around the report states that exemption would be justified "due to benefits that CdSe QDs could provide in terms of energy efficiency and in some cases also in relation to colour gamut."

“The intent of the RoHS Directive is to ban the use of hazardous substances in the EU. To recommend a continuation of the use of cadmium under this Directive in light of these inconclusive findings is misguided, at best, and irresponsible, at worst," said Michael Edelman, CEO of Nanoco, in a statement.

"Cadmium is an obsolete and hazardous technology that's never taken off in the mainstream market. In fact, sales of TVs using cadmium-free quantum dots already exceed those using cadmium by 20 to one. So why extend the use of this highly regulated and toxic chemical when there are safe alternatives available today that deliver market leading levels of color performance and energy efficiency?" he added.

카드-뮴 QD(quantum dots)-디스플레이 화소에 들어가는거.

카드뮴 QD 아마도 삼성이랑 엘지개새끼들 존나게 쓸 덧. 포항앞바다에 왜 카드뮴홍게가 잡히냐고? 내게 묻지말고, 생각이나 해라.

 

엘지디플공장 파주에도 있잖아. ㅋㅋㅋㅋㅋㅋ 연평도 꽃게 중국새끼들 다 주라. 나같으면 안 먹는다.

 

아 글고, 저거 규제되면 삼성이랑 엘지주가 모르긴 몰라도 10프로는 까진다.
