TCL’s German QLED ban puts pressure on TV brands to be more honest about QDs

March 20, 2026

Here's something that might surprise you — Germany just blocked TCL from calling some of its TVs QLED because they didn’t meet the legal standards for quantum dots. This court ruling in Munich is a big deal, especially because it puts a spotlight on how brands market these screens. Now, here's where it gets interesting — Samsung has been loudly criticizing TCL’s use of the term QLED, citing testing by Intertek that showed TCL’s TVs lacked enough of the chemicals, like cadmium and indium, that are key to true quantum dot tech. According to Scharon Harding writing in Ars Technica, TCL insisted they had solid proof for their claims, but the court’s verdict suggests otherwise. And get this — this isn’t just about one brand. It’s a wake-up call for the entire TV industry to be more transparent about what’s really inside those screens. So, as consumers, we should probably keep asking: are we really getting what we’re promised?

Germany recently banned TCL from marketing some of its TVs as QLED (quantum dot light-emitting diode), with a Munich court ruling that the TVs lack the quantum dot (QD) structure and performance associated with QLED TVs. The decision increases pressure on TV companies to be more honest with their marketing.

Samsung has actively campaigned against TCL’s use of the term QLED. A year ago, Samsung sent Ars Technica results from testing performed by Intertek, a London-headquartered testing and certification company, on TCL’s 65Q651G65Q681G, and 75Q651G. The results showed that the TVs lacked sufficient amounts of cadmium and indium (two chemicals used in QD TVs, either individually or in combination). Intertek reportedly tested the optical sheet, diffuser plate, and LED modules in each TV using a minimum detection standard of 0.5 mg/kg for cadmium and 2 mg/kg for indium.

At the time, a TCL representative told me that TCL had “definitive substantiation for the claims made regarding its QLED televisions.”
