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 significance is underscored 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 advancing.
In the television segment, Quantum Dot technology has long been one of the foundations of high-quality imagery. Samsung is its most consistent promoter and one of the leaders in development. In its 2025 offering, the manufacturer already has over 20 models utilizing quantum dots – from the QLED and Neo QLED Mini LED series to selected Samsung OLED televisions. Among them are models like the S85 in 55 inches, S90 in 65 inches, and S95F in 55, 65, and 77 inches. Such a wide range makes Quantum Dot no longer a solution exclusively for enthusiasts but instead reaches a much broader audience of users.
What are quantum dots and why do they matter
Quantum dots are semiconductor nanocrystals, around 10,000 times thinner than a human hair. Their key feature is the ability to emit very pure, precise colours when exposed to light. In Samsung QLED and Neo QLED TVs, the source of this light is blue LED diodes that excite the Quantum Dot layer. The effect is easy to notice – the colours are vibrant, natural, and clearly defined 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 significant role in modern televisions.
Ten Years of Samsung Experience
Samsung has been developing Quantum Dot technology for a decade. The first SUHD TVs with 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 readability of details—whether they are watching sports, movies, series, or HDR content. TVs with Quantum Dot maintain high image quality even in challenging lighting conditions, and the technology itself is characterised by a long lifespan. This makes it suitable for both everyday use and more demanding home entertainment scenarios.
TÜV Rheinland Certification and Real Image Quality
Not every television referred to as QLED actually utilises the full potential of Quantum Dot technology. That’s why independent certifications are important. TÜV Rheinland confirmed that Samsung QLED and Neo QLED televisions meet the standards set by the International Electrotechnical Commission (IEC) and employ the full layer of quantum dots in conjunction with blue LEDs. 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 granted 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’s easy to find a television that suits different needs. The most demanding users can opt for the Neo QLED Mini LED QN990F with 8K resolution, offering maximum image detail. Those looking for a well-priced 4K television will find suitable models in the QN90F and QN85F series, while fans of simplicity and minimalist design may choose the QLED 4K Q8F or Q7F.
Security 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 highlighting that the quantum dots used by Samsung are completely free of cadmium. This is confirmed by independent tests conducted by the international certifying body SGS (Société Générale de Surveillance). These solutions meet the requirements of the European RoHS directive, which regulates the levels 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 occurs in accordance with international health and environmental protection standards.
