Samsung Electronics Co., Ltd. today 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).[1]

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 the environment.

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.
