The question of OLED vs QLED is an important one to ask yourself when buying a new television these days. Even though the past decade has seen countless TV advancements and competing technologies, the battle of these two TV tech types is a close one – and largely, there is no right answer, just whatever is best for you, your preferences and your budget.
More crucial even than 4K vs 8K or Sony vs Samsung, OLED vs QLED is a question of what truly makes a premium picture and watching experience – the self-emissive delights of OLED, or the high brightness and quantum dot contrast of QLED technologies.
What about Black Friday and Cyber Monday?
It’s a good time to be shopping for a new TV, with Black Friday having kicked off, and plenty of Black Friday TV deals running throughout the weekend and into Cyber Monday. There’s a chance that top OLED and QLED TVs will be reduced, so keep checking back to TechRadar for the latest bargains. View Deal
However, unpicking the difference between these competing TV panel technologies, and what it means for you as a viewer, can be tricky for even knowledgable TV tech types. What even is OLED? Which TV brands offer which panel tech? How can you tell which you'll prefer before buying?
That's what we're here for: to simplify the jargon and ensure you have the information you need when on the lookout for a new living room set.
You'll now find Sony, Panasonic, Philips, Vizio and even Huawei pushing OLED TVs and extolling its virtues (even if Hisense quickly abandoned it after releasing its disastrous O8B OLED). This is by far the most widely supported premium panel tech – and is getting steadily cheaper – even if QLED has the advantage of being supported by Samsung, the world's largest TV manufacturer.

You could accuse QLED of simply being LCD by another name, having stemmed from a rebranding of Samsung's SUHD (Super UHD) sets a few years ago. The ever-expanding range could be said to undervalue the QLED name, too, though QLED still offers the best of Samsung's display technology, with a quantum filter that enhances contrast beyond what you'd usually expect from an LCD.
You will get the likes of TCL and Hisense pushing 'QLED' branded sets, so there's clearly more to it than Samsung's marketing team, too.
But which of the two, QLED and QLED, is really the real deal? We’ve collected together only the most important details you need to know about both QLED and OLED technologies – what they are, how they differ, and which TV makers support them. Read on for every OLED vs QLED question answered.
OLED vs QLED: the case for organic LED
OLED Pros and Cons
Pros:
Lighter and thinner (2.57mm)
Self-emissive pixels
More convincing blacks
Faster refresh rate (0.001ms)
Judder and blur-free
Cons:
Limited screen sizes: 48, 55, 65, 77, 88-inch
Muted brightness (up to 1,000nits)
Expensive
We can summarise the OLED vs QLED battle in one sentence: QLED is a tweak of existing LCD technology, while OLED is a new technology altogether.
OLED – which stands for Organic Light Emitting Diode – uses a carbon-based film between two conductors that emits its own light when an electric current is passed through.
Since the pixels themselves are producing the light, when they need to be black they get switched off completely. That means no chunky LCD backlight, remarkably realistic blacks, so-called 'infinite' contrast, lightning-quick refresh rates and a muted brightness ideal for movies – if dim by LED standards. Watching an OLED TV for the first time will give you that rare feeling of having just witnessed something really very special.
OLED has been stuck at only a few TV sizes for the past few years – given the smaller scale of its manufacturing compared to LED – though LG has now expanded to a 88-inch LG 8K OLED and is developing 48-inch panels to give viewers a wider choice of OLED sizes.
New light sensors installed in 2020 Panasonic and LG TVs are also improving how well OLEDs manage in bright environments, even if they're not used across the board yet.

QLED vs OLED: the case for quantum dots
QLED Pros and Cons
Pros:
Brilliant whites
Ultra-bright (up to 2,000nits)
Variety of screen sizes between 43 and 98-inch
Cons:
Not as slim (25.4mm)
Overly bright
Less convincing blacks
Slower refresh rate
QLED isn't a new TV technology as much as it is a rebrand. Until last year, Samsung called its flagship TVs SUHD, but that wasn't working as well as it hoped, so it's now called them QLED.
Yes, it sounds very, very similar to OLED, which suggests either a decision to intentionally confuse buyers with QLED – which stands for Quantum-dot Light Emitting Diode – but it's very different to OLED.
The weirdest thing is that QLED TVs are not QLED TVs. A QLED TV should be just like an OLED TV in having a panel that's self-emissive, so that it can switch individual pixels on and off. Samsung's QLED TVs can't do that, and in fact just put a quantum dot colour filter in front of an LCD backlight. It's premature to call them QLED, and they should really be called QLCD-LEDs. Thankfully, not even the acronym-riddled TV industry could live with that.
The inorganic quantum dot light-emitting diodes in a QLED panel do not emit their own light, but instead are illuminated by a backlight, just like any LCD TV. That's why they're not as thin as OLED TVs.
So, really, it's not a next-gen display technology at all, just a tweak to LCD TV tech. However, that doesn't mean it's not impressive – it really is very good.

Which brands support OLED & QLED?
The battle between OLED and QLED is a story about branding, and it's also about a South Korean rivalry. Every single OLED panel found inside every single OLED TV is made by LG Displays, and every single QLED panel is made by Samsung.
Team OLED:
Most TV brands are lining-up behind OLED, believing it to be the superior technology for picture quality. It's hard to disagree, but despite LG, Sony, Panasonic, TP-Vision (under the Philips brand in the UK), Loewe, Bang & Olufsen, Skyworth, and ChangHong all now selling OLED TVs, they do tend to be very expensive. The maker LG Display just can't produce enough OLED panels fast enough to bring them in at a lower cost, which is making OLED TVs seem like a top-tier premium TV technology only.
This is changing, with a new 48-inch OLED size, and long-term plans to ramp up production of panels of all sizes. Hisense has now ditched the technology, however – after a poorly-performing Hisense O8B OLED that didn't quite make the best case for the technology.
Team QLED:
Samsung abandoned its efforts to make OLED TVs in 2014 due to low production yields, and only started talking about QLED again back in 2017. It's now trying to popularize the technology by getting other companies involved.
Though the brands behind QLED are fewer, they're quickly getting unionised. Samsung, Hisense and TCL banded together under the QLED Alliance back in 2017, in order to advance QLED development – and shift more QLED sets in the world's biggest TV market, China.
OLED vs QLED: what's best for gamers?
If you're mainly interested in a television that's good for gaming, we'd encourage you to focus on different criteria than OLED vs QLED.
With the PS5 and Xbox Series X coming this year too, you may want to futureproof with a set carrying HDMI 2.1 ports that can carry 8K video from consoles (at 60Hz), as well as 4K video at 120Hz. Low input lag isn't always specified on TV product pages, but we recommend keeping an eye out for it nonetheless – or skipping to our best gaming TVs guide. This article on PS5-ready TVs runs through other specs and points of interest for buying a gaming TV too.
Certainly, OLED sets will be best for achieving natural contrast, and help make cinematic games – whether the intergalactic horizons of Halo Infinite or the lush forestation in Shadow of the Tomb Raider – look truly breathtaking. LG's OLED TVs come with Nvidia G-Sync to help smooth out gameplay onscreen too.
However, QLEDs go a lot brighter, and may be better for practical visibility in the games you're playing, and drawing out environments and in-game objects clearly. It may depend on what you're playing – but getting a set with low input lag, VRR (variable refresh rate), or an HMDI 2.1 port, will be more important than the underly panel technology.
Should you go with QLED or OLED in 2020?
If you're after a high-end 55-inch TV, buy an OLED TV, since both technologies are roughly the same price at that size. However, if you have something else on your mind – a smaller screen size and/or smaller budget to play with – it's more complicated that that.
Since LG Displays makes all OLEDs and Samsung all QLEDs, you might think that it's possible to draw grand conclusions about which tech is better with – for example – games, and which is better with movies. That's not the case. As with all consumer electronics products, it depends on (a) how much you spend, and (b) which brand you opt for.
Samsung's flagship QLED is the Samsung Q950TS 8K QLED TV, while the LG CX OLED best extols OLED's virtues. Check out our reviews of these two sets if you want to see the best both technologies have to offer – or wait to see what incoming sets for 2020 could replace them.
For cheaper televisions – under $1,000 / £1,000 / AU$1,500 – you'll have to stick with an LED or QLED television for now, as OLEDs simply aren't priced that cheaply yet. But you can get the Samsung Q60R QLED, for example, for only a few hundred dollars / pounds at its smallest 43-inch size.
There are plenty new Samsung TVs arriving for 2020, alongside a new slate of OLEDs from LG, Panasonic, Sony, and Philips – so there's plenty of opportunity for these stakes to change in the coming year.

The future for OLED vs QLED
Regardless of our buying advice for you today, it remains the case that things may shake up a lot in the coming years.
There are plans afoot to develop QLED sets that ditch the LCD backlight to become self-emissive, in a move that could blend the advantages of both OLED and QLED technologies and spell trouble for OLED panel manufacturers like LG Display.
"True QLED sets are self-emissive, as with OLED sets, and are not yet in the market, but are anticipated to be so in the coming years," says David Tett, Market Analyst at Futuresource Consulting. "When it is released it is expected to provide the strongest challenge to OLED yet, as it brings many of the same benefits as OLED, with few potential drawbacks."
There were initially rumors for Samsung to release these so-called 'true' QLED sets in 2020, which now seems far further off, though we continue to hear talk of Samsung working on some kind of OLED-QLED hybrid.
If the future is bright for QLED, those behind OLED panels are hoping that one of the technology's native characteristics, flexibility, wins the day. "OLED sets can offer new audio solutions that see the panel vibrate to create sound and could also offer new form factors, both due to their flexible nature of the panel," says Tett. This is nowhere clearer than with LG's incoming rollable OLED, the LG Signature Series OLED R, which is able to curl up into the television's base.
For now it's OLED that takes the crown for the best – and most expensive – TV tech around, but unless LG Display can up its production rate and create more screen sizes – as it's beginning to do – the immediate future of the mainstream TV could still belong to QLED.
