TCL faces backlash as its QLED TVs may not have any quantum dots

[DragonSlayer101]

TL;DR: Chinese tech company TCL is under the microscope following allegations from a South Korean quantum dot film manufacturer that some models of its QLED TV lineup do not contain quantum dot technology. The company denied the claims, citing results from a different test confirming that its QLED TVs use quantum-dot tech.

South Korean news site ET News notes that testing by two independent certification agencies, SGS and Intertek, found that the TCL C755, C655, and C655 Pro QLED TV models do not contain any signs of the elements indium and cadmium, which are essential to the creation of quantum dot nanocrystals. Hansol Chemical, which supplies quantum dot films to Samsung and other QLED TV manufacturers, commissioned the tests.

The television manufacturer denied the false advertising allegations, claiming all its quantum dot TVs contain actual quantum dot films.

"The QD content may vary depending on the supplier, but it definitely contains cadmium," the company explained.

The TLC press release also questioned Hansol's testing methodology, claiming it wasn't accurate enough to detect the exact amount of cadmium in the panels.

The company provided findings from a different test commissioned by one of its quantum dot film suppliers, also conducted by SGS, one of the agencies employed by Hansol. Its analysis reportedly found trace amounts of cadmium, while a spectrogram conducted on the QD film is also said to have confirmed the presence of quantum dots.

However, there is a critical difference between the two tests and the materials used to detect the presence of cadmium. Hansol's original analysis used actual TCL TV panels. The report TCL quoted examined QD films from its suppliers. It's unclear whether the films used in the models in question are from the same supplier as the ones TCL had tested.

After the ET News report broke in the west, TCL released a statement to Tom's Guide, claiming it doesn't sell any of the models in question in the US.

Quantum dot LED, or QLED, is a relatively new technology that offers enhanced color reproduction and superior picture quality. Quantum dots are manufactured nanocrystals that produce different colors depending on the particle size. They can emit precise colors because particle sizes adjust at quantum-level velocities, producing accurate and efficient light emission.

Another one is companies here advertise their sh***y TVs as GLOLED with emphasis on letters OLED.

How many languages did this get translated to before they translated it to English? That's not how quantum dots work.

 

[toooooot]

It seems they just wanted to make some extra cash selling these among their real qled tvs.
And the fact that they did not bring them to the US shows that they were aware they could have problems
with the law.
The article does not say anything about the price. Were they perhaps a bit cheaper models?

Also, what is a quantum level velocity that changes partcle size? That's sad.

I had to Google how quantum dots worked after reading this to make sure I wasn't having a stroke. I'm not exaggerating, either. So few times in my life have I seen such word gibberish that I thought something might be going wrong up there. I do have a neurological disease so it wouldn't be unreasonable to think this might be it. So, yes, I mean it literally. That was so poorly written I thought that I was having a stroke when I read that.

Oh, then it's fine I guess? lol...

QLED was a term Samsung made up for their LCDs with mini-led backlights to confuse customers back when LG had OLED and Samsung had nothing to compete. Why is TCL now the one getting blowback?!

Samsung is still using deceptive labeling. They are now selling WOLED by LG panels in the same TVs as their QD-OLED only the previous years. They're just calling them OLED now after championing QD as superior for years. It's a panel lottery as to which you get as there is no way to tell prior to purchase. It gets even better. If you get lucky and get QD panel, they still need to get rid of their stock of old 2nd gen panels from 2023 TVs so you'll get that in your 2024 models until they run out and then you will get a 2024 3rd gen panel.

Damn, it brings memories of getting my first decent monitor. Of course, there were 3 different panels sold under the same model name. Of course, one was the original Samsung with superior qualities and 2 from Samsung's suppliers with poorer qualities such as uneven backlight.

You can tell by the model/part number a letter change if WOLED vs QD-OLED, Think only on S90D range .
83" QD-OLED most likely next year, But yes if in market for WOLED get a Sony , LG, or Panasonic for better processing unless cheaper by right amount

Incorrect. If that was the case then why did edge-lit TVs also have Quantum Dot tech? It's meant to confuse, yes, but even their lowest end model of QLED which was edge-lit had them.
It was also was a means to have a greater color space coverage. It allowed them to stick with LED displays and avoid the pitfall of burn-in with early OLED displays.
