In the premium television market, there's a battle over what exactly is hidden under the name QLED. Samsung, which has been promoting quantum dot technology for years, has gone on the offensive – not just in laboratories but also in courtrooms. The company clearly communicates that the mere presence of nanocrystals in the display is not enough to offer a top-tier image. What matters is the way they are implemented, as confirmed by new, stringent certifications.
Court Final of the Dispute with TCL
The last few months have brought a breakthrough in the battle for the accuracy of labels on television boxes. Samsung won a high-profile case against the Chinese giant TCL. The European court ruled in favour of the Korean manufacturer, determining that TCL was using the term “QLED” in a way that could mislead customers.
As a result, the Chinese company received a ban on using the name for selected models that did not meet the technological requirements regarding the construction of the panel. For Samsung, this is not just a legal victory, but above all, a confirmation of their strategy: QLED is a specific quality standard, not a general advertising slogan for every television with “enhanced” colours.
"Not every quantum dot works the same way"
Samsung emphasises that the final visual effect is determined by the design of the panel. In televisions of this brand, the technology relies on a full layer of quantum dots and blue LEDs. This arrangement allows for precise colour separation – red, green, and blue do not mix, which is a common issue with cheaper alternatives.
The confirmation of these words is the certificate “Real Quantum Dot Display”, awarded by the independent organisation TÜV Rheinland. Researchers analyse the spectrum of light emitted by the screen, verifying whether the manufacturer's claims are backed by the actual physical properties of the panel. In 2025 and 2026, this certificate was awarded to as many as nine flagship models from Samsung, including the Neo QLED 8K (QN990F, QN950F) series and selected models of OLED.
Ecology and Safety: Cadmium-Free Dots
The technology war is also a fight for material safety. Samsung highlights in its press release that its quantum dot technology is completely free of cadmium. This is significant due to European environmental standards (the RoHS directive), as cadmium is a heavy metal that is sometimes used in cheaper solutions to achieve better colour saturation. By choosing certified screens, the user is therefore guaranteed that image quality aligns with safety for health and the environment, as confirmed by international research from SGS.
Samsung's message in the latest press release is clear: in 2026, just the term "QLED" won't be enough to ensure you're buying a top-tier product. The company aims to make the market more transparent, making it easy for customers to notice the difference between actual technology and marketing slogans.
