If you're shopping for a new TV, it's easy to get caught up in all the jargon, like HDR, 120Hz and HDMI 2.2. Then there's OLED and QLED. These terms describe entirely different TV technologies, and in side-by-side comparisons, one is consistently better than the other. For the last few years, Samsung has been branding most of its TVs as QLED. Its 2025 lineup includes Neo QLED models in 4K and 8K resolution. Samsung isn't the only one; TCL also makes QLED TVs. On the other side of the fence are OLED TVs. LG has dominated the OLED market, and its 2026 OLED TV lineup is more extensive than ever. Sony and Panasonic also sell OLED TVs in the US. Adding to the confusion, Samsung has multiple OLED TVs of its own, including the S90F, meaning it sells both OLED and QLED TVs. So what's the difference? Excellent question.

QLED vs. OLED: Quick summary

Let's start with a quick breakdown of these two technologies:

• OLED stands for “organic light-emitting diode.”
• QLED (according to Samsung) stands for “quantum dot LED TV.”
• OLED is a fundamentally different technology from LCD, the major type of TV.
• QLED is a variation of LED LCD, adding a quantum dot film to the LCD “sandwich.”
• OLED is “emissive,” meaning the pixels emit their own light.
• QLED, like LCD, is “transmissive” and relies on an LED backlight.
• Both QLED and OLED TVs are smart TVs with built-in apps.
• Both are capable of vivid colors and bright images, but some models are better than others.

A QLED TV is just an LCD TV with quantum dots

The main takeaway is that QLED is closer to regular old LCD than it is to OLED. The component that makes a TV a QLED is the incorporation of quantum dots. Quantum dots are microscopic molecules that, when hit by light, emit their own differently colored light. In QLED TVs, the dots are contained in a film, and the light that hits them is provided by an LED backlight. That light then travels through several other layers inside the TV, including a liquid crystal (LCD) layer, to create the picture. Because the light from the LED source is transmitted through the layers to the screen’s surface, we call it “transmissive.”

Samsung has been using quantum dots to augment its LCD TVs since 2015 and debuted the QLED TV branding in 2017. Samsung says those quantum dots have evolved over time, improving color and light output. In practice, improvements caused by better quantum dots are much less evident than those caused by other image quality factors, such as backlight dimming and viewing angle enhancements. TCL not only produces QLED TVs but is also the first company to use “Super Quantum Dots.” Other TV makers, including Vizio and Hisense, use quantum dots in LCD TVs but do not call those sets QLED TVs.

The size of the quantum dot determines what color it emits when supplied with energy. Currently, that energy is supplied by blue LEDs or blue OLEDs. This is a key point: QLED technology is still an LCD technology, and its performance depends heavily on the quality of the LCD panel, the backlight, and the processing electronics.

An OLED TV is not an LCD TV at all

LCD is the dominant technology in flat-panel smart TVs and has been for a long time. It’s cheaper than OLED, especially in larger sizes, and numerous panel-makers can manufacture it. OLED is different because it doesn’t use an LED backlight to produce light. Instead, light is produced by millions of individual OLED subpixels. The pixels themselves—tiny dots that compose the image—emit light, which is why it’s called an “emissive” display technology. That difference leads to all kinds of picture-quality effects, some of which favor LCD (and QLED), but most of which favor OLED.

OLED TVs don’t need LED backlights, so in addition to image quality benefits, they can get amazingly thin. Aside from the US brands mentioned above, Philips, Grundig, Loewe and others sell OLED TVs in Europe. All OLED TVs worldwide use panels manufactured by either LG or Samsung. Until 2022, LG was the only company making OLED panels, but that year Samsung started making its own panels using QD-OLED technology. Samsung promises improved color and brightness compared with current OLED TVs because its TVs use quantum dots—just like QLED TVs—and in tests, the color of the Samsung S95F QD-OLED was superb. Yet, the LG G5’s color was even better, in part because it uses another new OLED panel technology called “4-stack” to improve brightness. OLED technology continues to evolve.

QLED and OLED vs LED

Aren’t these all just “LED TVs?” No, at least not technically speaking. All LED TVs are LCD TVs that use LED lights as their backlight. Or to put it another way, all QLEDs are LEDs but not all LEDs are QLEDs. Despite sharing many letters, OLEDs are not LED TVs, at least not as far as marketing nomenclature is concerned. They use a different technology. You might also see Mini-LED TVs and even MicroLED TVs, though these are still mainly backlights to LCD screens.

QLED vs. OLED image quality

Based on reviews of both QLED and OLED TVs, here are some general comparisons.

QLED TV picture quality varies more than OLED

Samsung and TCL each have multiple QLED series, and the most expensive ones perform a lot better than the cheaper ones. The biggest improvements in the picture quality of QLED sets don’t have much to do with quantum dots. Instead, they’re the result of mini-LED backlights, better full-array local dimming, bright highlights, and better viewing angles. These features help them outperform QLED (and non-QLED) TVs that lack those extras. Meanwhile, every OLED TV reviewed has had very similar image quality—all earning top scores in picture quality tests.

OLED has better contrast and black level

One of the most important image-quality factors is black level. Their emissive nature means OLED TVs can turn unused pixels off completely, resulting in literally infinite contrast. With the recent introduction of TCL’s Halo Control technology, QLED/LCD TVs like the QM8K can finally approach OLED for black levels, though OLED is still capable of better contrast.

QLED is brighter

The brightest QLED and LCD TVs can get brighter than any OLED model, which is a particular advantage in bright rooms and with HDR content. However, OLED TVs can still get plenty bright for most rooms, and their superior contrast still allows them to deliver a better overall HDR image than any QLED/LCD TV tested.

OLED has better uniformity and viewing angles

With LCD-based displays, different areas of the screen can appear brighter than others, and backlight structure can be seen in some content. Even the best LCDs also fade, lose contrast, and become discolored when seen from seats other than the sweet spot directly in front of the screen. OLED TVs have almost perfectly uniform screens and maintain fidelity from all but the most extreme angles.

Resolution, color, and video processing

Most QLED and OLED TVs have the same 4K resolution, and both can achieve 8K resolution, too. Neither technology has major inherent advantages in color or video processing. Both are capable of accurate primary colors—reds, greens, and blues—but not all will be accurate out of the box. QD-OLED can deliver improved color, but standard OLED and even high-end QLED TVs also perform well.

QLED can get bigger and smaller (and cheaper)

The largest QLED TV is the Samsung 115-inch QN90F. OLED TVs are available in a more limited range of sizes. There are currently eight sizes of OLED TV on the market: 42, 48, 55, 65, 77, 83, 88, and 97 inches. Meanwhile, because QLED TVs are LCDs, they can be made in a greater range of sizes. Non-QLED LCD TVs can get even smaller. QLED sizes include 32, 43, 50, 55, 58, 65, 75, 82, 85, 98, 100, and 115 inches.

One big advantage that QLED and LCD have over OLED is the cost of mainstream sizes over 65 inches. Large televisions are the fastest-growing segment of the market. However, 77-inch OLED TVs cost significantly more than most 75-inch QLED TVs, and in larger sizes the difference is even more drastic. If you want a huge screen on a budget, QLED is the way to go.

What about OLED burn-in?

Burn-in happens when a persistent part of the image—a channel logo, a news ticker, or a scoreboard—remains as a ghostly background no matter what else appears on screen. All OLED screens can burn-in, and they’re more susceptible than LCD displays, including QLED. All things considered, however, burn-in shouldn’t be a problem for most people. Burn-in is typically caused by leaving a single, static image element on the screen for a long time, repeatedly. That’s an issue if you keep a news channel or sports network on for multiple hours every day and don’t watch enough other programming. But as long as you vary what’s displayed, chances are you’ll never experience burn-in.

Which is better in 2026 and beyond: QLED or OLED?

When pitting an OLED TV against a QLED TV, OLED wins every time in terms of picture quality. But there are other factors to consider. Beyond its QD-OLED TV, Samsung is researching a direct-view quantum dot, which dispenses with the liquid crystal layers and uses quantum dots themselves as the light source. Emissive QLED TVs have the potential to match the absolute black levels and “infinite” contrast ratio of OLED, with better power efficiency, better color, and more. That’s exciting, but it will be a few years before we see emissive QLED TVs for sale.

Then there’s MicroLED. It’s another emissive technology, once again spearheaded by Samsung but also sold by LG. It’s on sale now for the super-rich—the largest examples cost more than $1 million. As you might guess from the name, it uses millions of teeny-tiny LEDs as pixels. MicroLED has the potential for the same perfect black levels as OLED, with no danger of burn-in. It can deliver higher brightness than any current display technology, wide-gamut color, and doesn’t suffer from the viewing angle and uniformity issues of LCD. It’s also very large. It doesn’t involve quantum dots, at least not yet, but who knows what might happen when it comes to market.

For now, however, OLED rules the picture-quality roost over QLED.

QLED vs. OLED FAQs

Is OLED or QLED better?

For picture quality, OLED is better. However, QLED TVs tend to be brighter, which is good in rooms with a lot of natural light. OLED TVs typically have better contrast, so their images appear more lifelike. That said, we’ve liked TVs using both technologies and have recommendations for both on our best TV list, so it broadly comes down to your specific priorities and the model of TV you’re considering.

What is the lifespan of an OLED vs. QLED TV?

Manufacturers tend to be a little cagey when it comes to specific lifespans. Generally speaking, a TV should last at least five years—and probably a lot more. Lots of old LCD and plasma TVs are still out there working. OLED TV owners do have to worry somewhat about burn-in, but the concerns about that tend to be overblown. The truth is, your next TV could last 20 years or just two; it depends a lot on usage and the manufacturing of that specific model. The good news is, TVs get cheaper per screen inch every year. They’re one of the few modern products to consistently come down in price. So while no one wants to have to replace a TV, in five years, the same size and performance TV you get now will likely be significantly cheaper.
