Quantum dots are today one of the key technologies in modern electronics. They are used not only in TVs 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 – show how dynamically this field is developing.
In the TV segment, Quantum Dot technology has long remained one of the foundations of high-quality imaging. Samsung is its most consistent promoter and one of the leaders in development. In its 2025 lineup, the manufacturer already has over 20 models utilizing quantum dots – from the QLED and Neo QLED Mini LED series to selected Samsung OLED TVs. Among them are, for example, the S85 model in 55 inches, the S90 in 65 inches, and the S95F with diagonal sizes of 55, 65, and 77 inches. Such a wide offering means that Quantum Dot is no longer a solution exclusively for enthusiasts and reaches a much broader audience of users.
What are quantum dots and why do they matter
Quantum dots are semiconductor nanoparticles, about 10,000 times thinner than a human hair. Their key feature is the ability to emit very pure, precise colors under light exposure. In Samsung QLED and Neo QLED TVs, the source of this light is blue LEDs that excite the Quantum Dot layer. The effect is easy to notice – colors are intense, natural, and clearly separated from each other. The green of the field does not blend with other hues, and details in HDR movies gain depth and clarity. It is this precision of colors that makes Quantum Dot technology play such a significant role in modern televisions.
Ten Years of Samsung Experience
Samsung has been developing Quantum Dot technology for a decade. The first SUHD televisions with this solution appeared in 2015, and since then the manufacturer has been systematically improving the performance, stability, and efficiency of quantum dots. For users, this means better color reproduction, higher contrast, and greater detail readability—regardless of whether they are watching sports, movies, series, or HDR content. Televisions with Quantum Dot maintain high image quality even in more challenging lighting conditions, and the technology itself is characterized by a long lifespan. This makes it suitable for both everyday use and more demanding home entertainment scenarios.
TÜV Rheinland Certificate and Real Image Quality
Not every television labeled as QLED actually utilizes 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 utilize a full layer of quantum dots in combination with blue LEDs. The "Real Quantum Dot Display" certificate means that the user receives a real improvement in image quality – more accurate colors and a higher level of detail. In 2025, this certificate was obtained by 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 diagonal sizes, it’s easy to match a television to different needs. The most demanding users can opt for the Neo QLED Mini LED QN990F with 8K resolution, offering maximum image detail. People looking for a well-priced 4K television will find the right 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 mentioned televisions offer access to over 800 certified applications, support for the most popular streaming services, intuitive menus, and data security based on the Samsung Knox platform. It is also worth emphasizing that the quantum dots used by Samsung are completely free of cadmium. This is 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 takes place in accordance with international health and ecological protection standards.
