Quantum dots are today one of the key technologies in modern electronics. They are used not only in televisions but also in medicine, photovoltaics, and advanced optical sensors. Their importance is confirmed by the Nobel Prize in Chemistry awarded in 2023 for research on quantum dots, and the latest scientific experiments – including successful attempts at their teleportation – demonstrate how dynamically this field is developing.
In the television segment, Quantum Dot technology has remained one of the foundations of high-quality image for years. Samsung is its most consistent promoter and one of the leaders in development. In the 2025 product range, the manufacturer already has over 20 models utilising quantum dots – from the QLED and Neo QLED Mini LED series to selected Samsung OLED televisions. Among them are, for example, the S85 model in 55 inches, S90 in 65 inches, and S95F with diagonals of 55, 65, and 77 inches. Such a wide range ensures that Quantum Dot is no longer a solution exclusive to enthusiasts and appeals to a significantly broader audience of users.
What are quantum dots and why do they matter
Quantum dots are semiconductor nanocrystals, about 10,000 times thinner than a human hair. Their key feature is the ability to emit very pure, precise colours when illuminated. In Samsung QLED and Neo QLED televisions, the source of this light is blue LEDs that excite the Quantum Dot layer. The effect is easy to notice – colours are vibrant, natural, and distinctly separated from one another. The green of the pitch does not blend with other hues, and details in HDR films gain depth and clarity. It is this colour precision that makes Quantum Dot technology play such a crucial role in modern televisions.
Ten Years of Samsung Experience
Samsung has been developing Quantum Dot technology for a decade. The first SUHD televisions featuring this solution appeared in 2015, and since then the manufacturer has systematically improved the performance, stability, and efficiency of quantum dots. For users, this means better colour reproduction, higher contrast, and greater detail readability – regardless of whether they are watching sports, films, series, or HDR content. Televisions with Quantum Dot maintain high image quality even in more challenging lighting conditions, and the technology itself is characterised by long longevity. This makes it suitable for both everyday use and more demanding home entertainment scenarios.
TÜV Rheinland Certification and Real Image Quality
Not every television described as QLED actually utilises the full potential of Quantum Dot technology. Therefore, independent certifications are important. TÜV Rheinland has confirmed that Samsung QLED and Neo QLED televisions meet the standards of the International Electrotechnical Commission (IEC) and employ a full layer of quantum dots in conjunction with blue LED lights. The “Real Quantum Dot Display” certification means that the user receives a genuine enhancement in image quality – more accurate colours and a higher level of detail. In 2025, this certification was awarded to nine Samsung models:
Neo QLED 8K: QN990F, QN950F
Neo QLED 4K: QN90F, QN85F, QN80F, QN70F
QLED 4K: Q8F, Q7F, Q6F
With a wide range of screen sizes, it is easy to match a television to various needs. The most demanding users can opt for the Neo QLED Mini LED QN990F with a resolution of 8K, offering maximum image detail. Those looking for a well-priced 4K television will find suitable models in the QN90F or QN85F series, while fans of simplicity and minimalist design can choose the QLED 4K Q8F or Q7F.
Safety and ecology without compromise
All the televisions mentioned offer access to over 800 certified applications, support for the most popular streaming services, an intuitive menu, and data security based on the Samsung Knox platform. It is also worth noting that the quantum dots used by Samsung are completely free from cadmium. This has been confirmed by independent tests conducted by the international certification body SGS (Société Générale de Surveillance). These solutions meet the requirements of the European RoHS directive, which regulates the level of hazardous substances in electronics.
In practice, this means that Samsung televisions with Quantum Dot technology are safe for users and more environmentally friendly, and their production is carried out in accordance with international health and ecology protection standards.
