Samsung explains why OLED isn’t good for TVs

- Adrian Ungureanu

Well, it sounds a bit surprising to here the biggest OLED display producers in the world saying that OLED isnt’ good for TV, but Samsung explains why.

While for smartphones they say OLED display are great, for TVs is a total mindset. Why? Everything is about time. And the QLED displays used by Samsung on its TVs now.

OLED panels are good for devices that are used for years and years such as TVs or monitors because they have screen burn-in or image retention issues.

So, after a while, specially the permanent graphic elements will get imprinted in the screen overlaying the other images. Bellow you’ll see a burn-in example, on an Google Pixel 2 XL, which after just 2 weeks it has burn-in issues. It’s test unit reviewed by the guys ar Android Central, so they say, maybe it’s a problem with the first batch of smartphone produced and things will get fixed by Google. Even though Pixel 2 XL uses P-OLED and not AMOLED like other smartphones on the market, like Galaxy S8, Note 8 or iPhone X, is still a good example of what burn-in means on an OLED display.

Samsung of course is trying, also, to promote its QLED panels which rely on quantum-dot technology. They’re semiconductor nanocrystals that, according to Samsung, improve contrast, power efficiency and display brightness. Samsung also says that this crucial difference means that QLED TVs don’t suffer from burn-in issues.

Anyway, keeping it technical, they are right, OLED is not suitable for TVs. Some changes their smartphones in 2-3 years time, while TVs are expected to work even for 20 years without any problems, so I can understand why Samsung doesn’t like OLED TVs.
