Samsung Electronics Co., Ltd. announced that the quantum dot (QD) sheet used in its QD TVs has received certification for compliance with the Restriction of Hazardous Substances (RoHS) directive and has been verified to contain no cadmium by the global certification institute, Société Générale de Surveillance (SGS).
SGS, headquartered in Geneva, Switzerland, is a world-leading testing and certification body that provides services to ensure organizations meet stringent quality and safety standards across various industries, including electronic products, food, and environment.
In addition to receiving recognition from SGS for the no-cadmium technology in Samsung’s quantum dot film, the company’s compliance with the EU’s RoHS directive assures the safety of the TV viewing experience.
“Samsung’s quantum dot TVs are built on safe technology that complies with restrictions on hazardous substances while delivering unmatched picture quality,” said Taeyong Son, EVP of Visual Display Business at Samsung Electronics. “Achieving SGS certification fully validates the safety of our products. With this recognition, we are committed to continuously developing sustainable display technologies.”
Samsung began researching quantum dot technology in 2001, and its ongoing commitment to research and investment has positioned it at the forefront of innovation in the global display market.
After developing the world’s first no-cadmium quantum dot material in 2014, Samsung launched TVs that implemented the technology the following year. Since then, the company has been leading quantum dot technology through continuous technological advancements.
In particular, Samsung successfully created nanocrystal material without cadmium and has secured around 150 patents for the technology. With this extensive expertise and technological progress, the company has ushered in an era of safer quantum dot TVs made with materials that do not contain harmful substances.
