QLED TV

Quantum dots are ultra-fine nanomaterials — tens of thousands of times smaller than a human hair — renowned for their ability to reproduce vivid, precise colors depending on the light wavelength. The way quantum dots are integrated into display panels has become a key indicator for evaluating technological advancement in the premium TV segment.

Check for the ‘Real Quantum Dot Display’ certification logo from TÜV Rheinland, an international certification organization based in Germany. The certification verifies that Samsung’s QLED TVs meet global standards for quantum dot display structure, confirming that Samsung QLED TVs comply with the International Electrotechnical Commission (IEC) Draft Technical Report 62595-1-6, which describes the application of quantum dot (QD) light converting unit combined with blue light sources for standard QLED displays.

As part of the certification process, TÜV Rheinland analyzed the light spectrum produced by Samsung QLED TVs and confirmed that it displayed clear separation between red, green and blue — an important marker of color accuracy. With this certification, Samsung’s QLED TVs are officially validated as true quantum dot displays, delivering true quantum dot performance built to international standards.

Samsung’s quantum dot technology has also been recognized by global testing organization Société Générale de Surveillance (SGS) for its excellence in cadmium-free design — an environmentally conscious approach that eliminates the use of cadmium, a toxic heavy metal known to pose risks to human health and the environment.

A QLED TV is a high-end TV that lights up nanoscale-sized particles called Quantum Dots to reproduce the images on screen, which results in enhanced brightness and color accuracy. In fact, "QLED" stands for "Quantum Dot Light Emitting Diode" in reference to this technology. When a QLED TV's backlight is turned on, each tiny Quantum Dot radiates light in a specific color. With precise control over these nanoscale-sized light particles, QLED TVs can produce a wide range of colors no matter how bright the screen. It's worth getting a QLED TV if you want to immerse yourself fully into your content, such as your favorite sports match or video game. With high visual fidelity and enhanced color and brightness, QLED screens create a vivid viewing experience that really draws you into the action. If that's what you want, then a QLED TV is well worth it.

The major difference between Samsung QLED, OLED and Neo QLED TVs is the lighting technology. QLED TVs use nanoscale-sized particles called Quantum Dots illuminated by a traditional backlight. Meanwhile, OLED TVs use self-illuminating pixels on screen and don't have any backlight at all. Neo QLED TVs use Quantum Dot technology similar to QLED TVs, but their backlight design is made up of mini-LEDs for more precise lighting control. This difference in lighting technology for QLED, OLED and Neo QLED TVs leads to subtle differences in picture quality, such as for color, contrast and brightness, and even affects the physical design of the TV itself. To learn more about QLED, OLED and Neo QLED TVs, see our TV buying guide that breaks down all the differences and what they mean for design, picture quality and more.

QLED TVs use inorganic materials that put less stress on the screen, which helps prevent burn-in issues and contributes to longevity.

While a QLED TV is considered a higher-end model than a Crystal UHD TV, it isn't necessarily better for you depending on your needs and budget. Both QLED and Crystal UHD TVs are designed to produce a rich range of colors with HDR support, resulting in an amazingly bright and vibrant screen. However, QLED TVs have special nanoscale-sized particles called Quantum Dots, each of which can radiate light in a specific color. With these tiny colored lights, QLED TVs are able to produce superior color accuracy and enhanced brightness. Because of this advanced technology, QLED TVs tend to be more expensive than Crystal UHD TVs. So while QLED TVs offer better color accuracy and brightness, Crystal UHD TVs are still bright and colorful enough for general viewing purposes. However, if QLED TVs are within your budget, then you should definitely consider upgrading to one, especially if you want to immerse yourself into an on-screen experience like a sports match or video game.

You should choose your QLED TV based on specifications like size, 4K resolution, HDR support and price. That being said, Samsung sets the industry standard for QLED TVs, so a Samsung QLED TV is generally a safe choice. Screen size is one of the most important factor for choosing a QLED TV. Samsung offers QLED TVs in a wide range of sizes, from 32 inches to 85 inches. While a bigger screen size is better for immersion, you should also consider what can fit into your space. If you need help finding the right TV size, please consult our TV size buying guide. Resolution is another important factor for choosing a QLED TV. For a sharp and detailed picture, go for a TV with a 4K resolution, which is offered on all Samsung QLED models. HDR support is yet another important factor for choosing a TV. This is because QLED technology can produce incredibly high peak brightness, while HDR (High Dynamic Range) helps determine the maximum brightness the screen can achieve. Fortunately, all Samsung QLED TVs have HDR support, so you don’t need to worry about this feature when choosing a Samsung model. Lastly, consider the price. Although QLED TVs are seen as a high-end technology, their cost really depends on the exact model and specifications. However, Samsung QLED TVs come in a wide price range, so you have a lot of options when it comes to budget.

The best TV for you to buy depends on personal factors like budget, room and purpose. While high-end TVs like QLED, OLED and Neo QLED models provide an amazing experience, the best TV for you varies according to your specific needs.
