The picture quality of QLED televisions varies more than that of OLED televisions.
The different companies both have multiple QLED series, with the more expensive ones performing noticeably better than the less expensive ones. This is primarily because the most significant improvements in the picture quality of QLED sets have little to do with quantum dots. Instead, they result from mini-LED backlights, improved full-array local dimming, bright highlights, and wider viewing angles, which enable them to outperform QLED (and non-QLED) TVs without those extras.
Meanwhile, every OLED TV we’ve reviewed has very similar image quality; all received a 10/10 in my tests. There is some variation among different OLED TVs, such as the LG A2’s 60Hz panel versus 120Hz on other OLED TVs. Still, it is not nearly as significant as the differences between various QLED TV series.
The contrast and black level of the OLED are higher.
One of the most important picture quality factors is black level, and because OLED TVs are emissive, they can completely turn off unused pixels for literally infinite contrast. Even the best QLED/LCD TVs with the most effective full-array local dimming let some light in, resulting in washed-out, grayer black levels and blooming around bright sections.
QLED is more visible.
The highest QLED and LCD TVs can get brighter than any OLED model, which is especially useful in bright rooms and when viewing HDR content. However, in tests, OLED TVs are still bright enough for most rooms, and their superior contrast allows them to deliver a better HDR picture than any QLED/LCD TV I’ve tested.
QLED displays can become larger and smaller (and cheaper)
There are currently six sizes of OLED TV on the market, with two more sizes, 42-inch and 97-inch, coming in 2022.
Meanwhile, because QLED TVs are LCDs, they can be made in wider sizes. Non-QLED LCD TVs may become even more compact.
One significant advantage that QLED and LCD have over OLED is the cost of mainstream sizes larger than 65 inches. Large televisions are the market’s fastest-growing segment, and they showing no signs of slowing down. cost77-inch OLED TVs is $2,500 and up, which is significantly more than most 75-inch QLED TVs, and the difference is even more pronounced in larger sizes.
What about burn-in on OLEDs?
Burn-in occurs when a persistent part of an image, such as navigation buttons on a phone or a channel logo, news ticker, or scoreboard on a TV, remains a ghostly background regardless of what appears on the screen. All OLED screens can burn in, and from what we’ve heard, they’re more prone than LCD displays, including QLED.
OLED VS QLED TVs: which is superior in 2022 and beyond?
As we previously stated, when we pitted the best 2021 OLED against the best 2021 QLED, OLED won again, as it has in previous years.
What about tomorrow? Aside from its upcoming QD-OLED TV, company working on direct-view quantum dot technology, which eliminates the liquid crystal layers and uses quantum dots as the light source. Emissive QLED have the potential to match OLED’s absolute black levels and “infinite” contrast ratio, while also providing better power efficiency, color, and other benefits. That’s pretty exciting, but we won’t see emissive QLED TVs for sale for a few years. Hopefully, by then, they’ll have come up with a new acronym (EQLEDs?).
MicroLED is another option. Another emissive technology, this time spearheaded by company but also sold by LG, is now available for the ultra-rich – the largest examples cost more than $1 million. As the name suggests, it employs millions of teeny-tiny LEDs as pixels. MicroLED has the potential to achieve the same perfect black levels as OLED while avoiding burn-in. It has a higher brightness than any other current display technology, a wider color gamut, and does not have the viewing angle and uniformity issues that LCD does. It’s also ridiculously large. It doesn’t yet involve quantum dots, but who knows what will happen when it hits the market.
