The LCD panel - essentially millions of tiny shutters that open and close too quickly to see - in conjunction with the color filters create the picture you see by letting just the right amount of light and color escape and reach your eyes. The FTC ultimately took Samsung’s side, but with a stipulation: It must make it clear in future advertisements that its QLED TVs use a backlight. In a retaliatory move, Samsung told the FTC it was unhappy with all of the ads LG had been running, which attacked Samsung’s QLED TVs. That’s because, according to LG, a true QLED TV would use quantum-dot LEDs that emit their own light, and not the quantum-dot-film-over-an-LED-backlight that Samsung uses. In a complaint to South Korea’s Fair Trade Commission (FTC), LG claimed that Samsung’s so-called QLED TVs aren’t real QLED TVs at all. It’s these LEDs that give LED (and QLED) its name.Ĭuriously, it’s this use of QLED as a marketing term that started a war between LG and Samsung in 2019. How do quantum dots work? Check out our deep dive into the technology for all of the details.Īs cool as quantum dots are, a QLED TV still produces light more or less the same way as a regular LED TV: By using a backlight made up of hundreds (or in some cases thousands) of LEDs, which sits behind a traditional LCD panel. The technology was introduced by Sony in 2013, but shortly after that, Samsung began selling its QLED TVs and established a licensing partnership with other manufacturers, which is why you’ll also find QLED TVs from Vizio, Hisense, TCL, and many small brands too. In non-geek-speak, that means a QLED TV is just like a regular LED TV, except it uses tiny nanoparticles called quantum dots to super-charge its brightness and color. QLED stands for Quantum Light-Emitting Diode. Once you’ve settled on which TV tech is right for you, check out some of the best QLED TV deals and the best OLED sales available now. Spoiler: It’s OLED TV - but with a few caveats you need to be aware of. We’ll also share which one we think most people will be happiest with. We’ll discuss QLED versus OLED, where these competing display technologies come from, how they’re different from each other, and what each one does well (and not so well).
