4K vs OLED: which TV technology is more important?


If you’re wondering if 4K or OLED is the tech right now, you’re not alone. Anyone who tries to buy a new television will be inundated with new TV buzzwords, and of all perhaps the two most important to understand are OLED and 4K.

So what is it, OLED or 4K? In fact, you can have both. But you don’t need To. There are OLED TVs that don’t offer 4K (instead, go for the more expensive 8K resolution) and there are plenty of 4K TVs available that don’t use OLED display technology.

However, most of the best 4K TVs are actually OLED TVsSo it’s worth seeing how the technologies intertwine, what specific models exist, and why you should think about investing in OLED and 4K, if not both.

Why OLED versus 4K?

It’s not really a case of OLED versus 4K. One is display technology and the other is the resolution of most newer televisions. You can find OLED TVs with 4K resolutions, but there are many 4K TVs that use display technologies like LCD, LED, Micro LED and QLED, which are nothing like OLEDs.

Do you need 4K? Probably yes. Going for a lower resolution TV would be ignoring one of the most common TV features. This is not the case with OLED, which is a flagship TV display technology that requires a significant additional investment. Yes, it gets more and more affordable every year, but you should only make an active decision to buy an OLED TV after you understand why it is the best AV technology on the market.

So let’s start by investigating what’s so good – and bad – about OLED and 4K to help you make the right decision when buying a new TV.

What is OLED?

Available for over a decade in consumer televisions, Organic Light Emitting Diode (OLED) is a display technology that uses a carbon-based film between two conductors that emits its own light when an electric current is passed through. The pixels are self-illuminating and individually controlled. This allows two pixels side by side to simultaneously produce deep black and bright white. The result is incredible contrast and color, while such pixel-level control means high refresh rates, so no stuttering or motion blur. Once you’ve watched an OLED TV, it’s really hard to go back.

In contrast, OLED TVs can look a bit darker than LED or QLED TVs, although new light sensors and innovations for 2021 improve the performance of OLED TVs in bright environments.

OLED TV panels are exclusively manufactured by LG Display in South Korea, although these panels are used in televisions sold by LG, Sony, Panasonic and Philips.

What is 4K?

A sharper magnitude than older ‘Full HD’ televisions, 4K resolution – also called Ultra HD – is a shortcut for 3840×2160 pixels. This is an 8 megapixel image as opposed to the 2 megapixel images in a Full HD set, which gives a lot more detail in your images.

4K vs OLED pricing: how much do they cost?

Where OLED and 4K compete is on price. You can easily buy a 4K TV – in fact, now it’s incredibly hard not to, unless you choose a really small TV – but if you buy an OLED TV, it will cost you dearly.

Most OLED TVs are flagships of major TV brands, or pretty much so. Over the past couple of years that has changed slightly, with the more expensive OLED sets offered by LG, Sony, Panasonic and Philips offering 8K resolution.

8K OLED TVs are out of almost everyone’s price bracket and, for now, just loss-making brand extension products that we all could dream of having, but absolutely don’t need. This is certainly not true for 4K OLED. Here’s what you need to know about the 4K OLED TVs currently available from major brands.
