Reports say controversy is brewing over discrepancies between the key spec figures Chinese-made TVs disclosed to the market and the actual measured results.
According to a review of TCL's new "X11L SQD Mini LED" released by the U.K. IT outlet "TechRadar" on the 26th, the product launched claiming support for 100% of BT.2020 and 100% of DCI-P3 color gamut, but actual measurements were 91.8% and 97.9%.
BT.2020 and DCI-P3 are "color gamut standards," meaning the range a screen can display, and the higher the figure, the wider the color reproduction. TechRadar said, "In particular, for DCI-P3, it appears there has been no technological advancement, with performance almost the same as the previously released model QM9K."
The brightness (luminance) figures are also reported to differ. At a 5% APL (the proportion of bright areas on the screen), TCL emphasized a peak of 10,000 nits (nit; 1 nit is the brightness of a single candle), but the measurement was found to be 9,394 nits. At 10% and 100% APL, the figures were 2,679 nits and 460 nits, respectively, and 100% APL, which refers to scenes where the entire screen is bright, was analyzed as lower than competing models.
Earlier, in the first half of last year, TCL faced a class-action lawsuit in Riverside County Superior Court in California over alleged false advertising. The claim was that some Chinese-made QLED TVs advertised quantum dot (QD) technology despite not including it or including it at a minimal level. Another Chinese TV maker, Hisense, also faced a class-action lawsuit in February last year in the U.S. District Court for the Southern District of New York for alleged violations of consumer protection laws.
