A Munich court has prohibited TCL from labeling specific television models as QLED, ruling that these sets do not meet the expected quantum dot standards. This legal decision intensifies scrutiny on how TV manufacturers describe their products to consumers.
Samsung initiated the lawsuit that led to this ruling. The company had previously shared test results from Intertek, a London-based certification firm, which analyzed TCL’s 65Q651G, 65Q681G, and 75Q651G models. Intertek’s examination of optical sheets, diffuser plates, and LED modules found cadmium and indium levels below detection thresholds of 0.5 mg/kg and 2 mg/kg, respectively.
At the time, TCL asserted it had solid evidence to support its QLED marketing claims. However, independent online teardowns and expert analyses suggest these TVs may incorporate some quantum dots but not in quantities that significantly enhance color gamut compared to non-QD alternatives.
Many televisions advertised as QD or QLED, particularly in budget segments, often depend on phosphors or mixed phosphor-QD blends for color conversion. Phosphors are less expensive than quantum dots and generally deliver inferior color performance in displays.
Other brands, including Samsung, have faced accusations of marketing phosphor-heavy TVs under QD or QLED labels. This widespread practice has blurred the definitions of these terms, enabling companies to potentially exaggerate QD usage to justify premium pricing and stimulate sales.
The Munich court’s ruling specifically targets TCL’s QLED870-series sold in Europe, deeming its QLED marketing misleading. While Samsung’s involvement invites some skepticism due to competitive rivalry, the verdict underscores a broader industry issue with ambiguous marketing language.
