Samsung is among the leaders in display technology worldwide. In 2014, the Korean firm developed the first no-cadmium Quantum Dot material and successfully commercialized it the following year. Since 2017, Samsung has been making progress in Quantum Dot technology using QLED TVs, which is the companyโs own Quantum Dot TV series. The global certification institute SGS (Sociรฉtรฉ Gรฉnรฉrale de Surveillance) recently recognized this innovation.
SGS testing confirms the quantum dot film is cadmium-free
In its Newsroom post, Samsung has confirmed that its Quantum Dot sheet in TVs is certified as Cadmium-free (No Cd) by SGS, a world-leading testing and certification body in Geneva, Switzerland. In addition to that, the Quantum Dot sheet is compliant with RoHS standards. RoHS refers to the Restriction of Hazardous Substances, and itโs a directive from the EU. It restricts the use of hazardous substances.
For example, Cadmium has the potential to cause cancer, though the use of Cadmium quantum dots in TVs enhances colour and image contrast. This heavy metal is highly toxic, and hence, itโs good that Samsung is focusing on user safety and compliance with regulations. This nanocrystal material, without Cadmium, required 150 patents and a lot of technological research and innovation.
The Korean firm has actually been working on Quantum Dot technology research since 2001, so itโs clear that the innovation didnโt happen overnight. โSamsungโs quantum dot TVs are built on safe technology that complies with restrictions on hazardous substances while delivering unmatched picture quality,โ said Taeyong Son, Executive Vice President at Samsungโs Visual Display Business. โAchieving SGS certification fully validates the safety of our products.โ
Quantum dots make use of ultra-fine semiconductor particles. They are tens of thousands of times thinner than even human hair. Due to their physical characteristics, they can provide high levels of colour accuracy and high brightness. They support a wide gamut of colours, and it closely matches the colour perception of the human eye.
This technology also adjusts the pixels to enable good reproduction of darker colours and blacks. Since Quantum Dots emit light in all directions, they can provide a uniform luminance, proper viewing angle, low blue light exposure, which is straining for the eyes, etc.
