Buying a new TV in 2022 is still confusing. The best TVs advertise a mind-boggling lot of features like HDR, Ultra HD 4K, 120Hz, and HDMI 2.1, so it’s hard to know what’s really worth it. The two most important TV terms are QLED and OLED. They are separated by a letter, but the techniques they describe are very different.
In recent years, Samsung has called its TVs QLED “. The 2022 QLED lineup includes Neo QLED models with 4K and 8K resolution, The Frame art TV with Q everywhere, and rotating Serif and Sero TVs. Not just Samsung. TCL also makes QLED TVs, including CNET’s Editors’ Choice 6 series.
On the other side of the fence is an OLED TV. In recent years, LG has dominated the OLED market, and while the 2022 OLED TV lineup is bigger than ever, Sony and Vizio are also making OLED TVs in the US. And to add to the confusion, Samsung launched its own TV. 2022, so it will sell OLED and QLED TVs this year.
So what is the difference between OLED and QLED? Let’s start with quality. In our side-by-side comparison review, OLED beats QLED every time. We compare the best LG OLED TV 2021 – LG G1 series – with the best Samsung QLED TV 2021, QN90A series. Although Samsung QLED and LG OLED, LG still wins. A more recent example is the competition between LG OLED C2 and TCL 8K QLED TV in 2022, and OLED TV won again this time.
As we review more TVs this year, we expect OLED TVs to continue to outperform QLED TVs. This is why.
QLED TVs are just LCD TVs with quantum dots.
The main conclusion is that QLED looks more like an old LCD than OLED. I and most other experts see OLED as a very different type of television, like plasma before it.
Quantum dots are microscopic molecules that emit their own light of a different color when exposed to light. In QLED TVs, the dots are embedded in the film and the light hitting the dots is provided by the LED backlight. This light then passes through several other layers inside the TV, including the LCD (liquid crystal) layer to create an image. The light from the LED source passes through the coating to the surface of the screen, so it is called ‘s Transmissive “.
Look at the “sandwich” layers of LCD televisions where the LED backlight shines in the LCD panel itself through a layer of quantum points (among other things).
Samsung uses the quantum points to improve LCD televisions from 2015 and the QLED TV brand in 2017. Samsung has confirmed that quantum points are changing according to the time, that the color and the illumination are improving, for example. In my experience, however, the improvements caused by better quantum dots are much less obvious than those caused by other image quality factors (see below).
Other TV makers also use quantum dots in LCD TVs, including Vizio and Hisense, but don’t call those TVs QLED.
Best OLED TV and LCD TV
LCD is the dominant technology for flat panel televisions and has been around for a long time. They are cheaper than OLED, especially in larger sizes, and many panel makers can make them.
OLED TVs do not require an LED backlight. So apart from the image quality benefits, it can be pretty flimsy.
OLED is different in that it doesn’t use an LED backlight to produce light. Instead, millions of individual OLED subpixels produce light. Because the pixels themselves (the tiny dots that make up the image) emit light, they are called “radial” display technologies. This difference causes all kinds of image quality effects, some of which support LCD (and QLED), but most of which support OLED.
In addition to the above-mentioned American brands, Panasonic, Philips, Grundig, etc. they also sell OLED TVs in Europe. All OLED TVs in the world, including the US, use panels from LG Display.
But that will change soon. Samsung and Sony will soon launch the first OLED TVs made by Samsung Display. Because it uses quantum dots like QLED TVs, it promises improved color and brightness compared to existing OLED TVs. Called QD-OLED or QD screens, they will initially cost much more than standard OLED TVs, but they will be quite expensive at first, but eventually the price will come down.
Image quality QLED vs. OLED
Here are some general comparisons of the two based on my review.
Samsung and TCL each have several QLED series, with the more expensive outperforming the cheaper ones. This is mainly because the biggest improvement in image quality in QLED arrays has nothing to do with quantum dots. On the other hand, it outperforms QLED (and non-QLED) TVs that don’t have these additional features, thanks to the mini LED backlight, better full array local dimming, brighter reflections and better viewing angles.
Meanwhile, all the OLED TVs I reviewed had very similar picture quality. They all scored 10/10 quality in my tests. There are some differences between the various OLED TVs, for example the LG A2 with a 60Hz panel compared to 120Hz for other OLED TVs, but these are not as important as the differences between the different QLED TV series.
One of the most important picture quality factors is black levels, and their luminous nature means OLED TVs can completely turn off pixels that aren’t being used, providing truly limitless contrast. QLED/LCD TVs, even the best with the most efficient full-array local dimming, let light in, resulting in deeper blacks and highlights around lights.
The brightest QLED and LCD TVs can be brighter than any OLED model, which is especially advantageous in bright rooms and HDR content. However, in my tests, OLED TVs can still be very bright in most rooms, and thanks to their excellent contrast ratio, they can deliver better full HDR images than any QLED/LCD TV.
For LCD screens, different areas of the screen may always appear brighter than others, and some content may also have a backlight pattern. Even the best LCD screens will fade, fade and change color when viewed from a seat other than the sweet spot directly in front of the screen. OLED TVs have near-perfectly smooth screens and maintain precision at all but extreme angles.
Most QLEDs and OLEDs have the same resolution and 4K, and both can go up to 8K resolution. While QD-OLED can provide enhanced color, neither technology has a significant inherent advantage in color or video processing. See OLED vs LCD for more details.
QLED could be bigger and smaller (could be cheaper)
Launched only in 2022, LG will sell its biggest OLED TV ever, the 97-inch G2.
There are currently 6 sizes of OLED TVs on the market and two new sizes will be added in 2022: 42 inches and 97 inches.
On the other hand, because the QLED TV is an LCD, it can be made in more varied sizes. Non-QLED LCD TVs could be smaller.
In other words, the big advantage that QLED and LCD have over OLED is the cost of a standard size of 65 inches or more. Large format TVs are the fastest growing market segment and show no signs of slowing down. A 77-inch OLED TV costs more than $2,500, which is significantly higher than most 75-inch QLED TVs, and the difference is even greater at larger sizes.
What about the burnt OLED?
Burn-in occurs when a permanent part of an image (such as a navigation button or channel logo on a phone, a ticker, or a control panel on a television) remains as an eerie background, regardless of what is displayed. on the screen. All OLED screens can burn in and are more sensitive than LCD screens, including QLED.
But all things considered, burn-in isn’t a problem for most people. All the evidence we’ve seen suggests that burn-in usually occurs due to leaving a single static image element, such as a channel logo, on the screen for an extended period of time. , many times. For example, if you leave Fox News, ESPN, or MSNBC on for a few hours each day and don’t watch enough shows, that’s a problem. But chances are you won’t experience a one-time change in what’s displayed.

After 2022, which is better, QLED TV or OLED TV?
As mentioned above, while competing with the best 2021 OLED against the best 2021 QLED, OLED continues to win, just like in previous years.
What about the future? In addition to the upcoming QD-OLED TV, Samsung is investigating a direct-view quantum point that passes through the liquid crystal layer and uses the same quantum dots as a light source. QLED TVs radiate the potential to match the absolute black level and “unlimited” contrast ratio of OLED with better energy efficiency, better colors and more. That’s interesting enough, but it will be a few years before emission QLED TVs go on sale. Hopefully, they will come up with a new acronym (EQLED?).
And then there’s MicroLED. Another emerging technology, again led by Samsung but also sold by LG, is currently being sold to wealthier people. The largest examples cost more than a million dollars. As the name suggests, it uses millions of tiny LEDs as pixels. MicroLEDs have the potential to achieve the same perfect black levels as OLEDs without the risk of burning out. It can provide higher brightness and a wider color gamut than current display technologies, and does not suffer from the viewing angle and uniformity problems of LCD screens. It is also huge. It doesn’t contain quantum dots, at least not yet. But when it comes to markets, who knows what will happen. QDMLED, anyone?
But for now, OLED dominates picture quality over QLED.
