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 65Q651G, 65Q681G, 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.”
