In the premium television market, there is a battle over what is actually implied by the name QLED. Samsung, which has been promoting quantum dot technology for years, has taken an offensive stance – not only in laboratories but also in courtrooms. The company clearly communicates: the mere presence of nanoparticles in the panel is not enough to offer top-quality image. What matters is how 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 fight for the accuracy of labels on television boxes. Samsung won a high-profile lawsuit against the Chinese giant TCL. The European court ruled in favour of the Korean manufacturer, stating that TCL used the term “QLED” in a way that could mislead customers.
As a result, the Chinese company was banned from using this name for selected models that did not meet the technological requirements concerning the construction of the panel. For Samsung, this is not only a legal victory but above all a confirmation of its strategy: QLED is a specific quality standard, not a general advertising slogan for any television with "enhanced" colours.
"Not every quantum dot functions the same"
Samsung emphasises that the final visual effect is determined by the panel's construction. 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 together, 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, checking whether the manufacturer's claims are backed up 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 OLED models.
Ecology and Safety: Cadmium-Free Dots
The technology war is also a struggle for material safety. Samsung emphasises in its press release that its quantum dot technology is completely free from 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 thus receives a guarantee that image quality goes hand in hand with safety for health and the environment, as confirmed by international studies from the SGS organisation.
Samsung's message in the latest press release is clear: in 2026, the term "QLED" alone will not be enough to guarantee the purchase of a high-end product. The company aims to make the market more transparent, so that the difference between actual technology and marketing slogans is easy for customers to notice.
