The argument is not whether the televisions are good. It is whether a backlight that dims in software can be sold under a name that describes hardware.
TCL North America has sued Samsung Electronics America in a California federal court, alleging that three of Samsung’s 2026 televisions are marketed as Mini LED sets without the backlight hardware the term implies.
What Was Filed
The complaint was filed on Monday 31 August 2026 in the United States District Court for the Central District of California, in Los Angeles. Counsel is the firm Larson LLP.
The claims are brought under the federal Lanham Act and under California false-advertising and unfair-competition law. TCL seeks an injunction and unspecified monetary damages.
The plaintiff is TCL North America, headquartered in Irvine, California, the American arm of China’s TCL Technology. The defendant is Samsung Electronics America, the United States subsidiary of the Korean group.
The Technical Allegation
The televisions at issue are Samsung’s 2026 M Model sets: the M70H, M80H and M90H.
TCL’s specific complaint is that these sets lack full-array local dimming, relying instead on edge lighting and software-based dimming, while Samsung markets them using the phrase Supreme Mini LED Dimming.
The distinction is real and consequential for picture quality. Mini LED as the industry has used the term describes thousands of small backlight elements behind the panel, individually dimmable in zones. An edge-lit panel has its lights along the border and simulates zone control in processing.
Why the Term Is Worth Fighting Over
Mini LED has become the label consumers use to identify a premium backlight without paying organic-LED prices, and it commands a price premium over conventional LED sets.
If the term can be applied to an edge-lit panel with software dimming, it stops functioning as a specification and becomes a marketing category. That is the outcome a manufacturer investing in the hardware has the strongest reason to resist.
TCL’s own genuine Mini LED line, the QM range, is the product the disputed Samsung sets would be competing against on shelf.
What Samsung Says
Samsung Electronics America has said it stands fully behind the quality and accuracy of its product descriptions.
It is worth noting that the two companies have litigated in the other direction as well: Samsung prevailed in a German case against TCL over what it characterised as fake quantum dot televisions. Neither company comes to this dispute with clean hands on advertising claims.
The Market Behind the Case
TCL claims it overtook Samsung in United States Mini LED sales between 2023 and 2025. Independent data does not fully support the framing: Counterpoint Research indicates that both TCL and Hisense passed Samsung in the Mini LED segment in 2024.
The broader pattern is the same either way. Chinese manufacturers have taken share in the premium television segment that Samsung and LG dominated for a decade, competing on specification at lower prices, and the specification is what this case is about.
What Would Settle It
A false-advertising claim of this kind usually turns on whether the term has an established meaning in the trade and whether consumers rely on it. Both are evidentiary questions, answered by surveys and industry testimony rather than by teardowns alone.
An injunction would be the outcome with consequences beyond the parties, because it would fix what Mini LED may describe for everyone selling into the United States.
