When it was first reported that Apple was going to use an OLED panel on the iPhone X, many users raised concerns about the display aging poorly and having burn-in issues which are typical with OLED panels. This was despite Apple sourcing OLED panels from Samsung which is known for its quality OLED panels.
A new test now compares the OLED panels on the iPhone X, Samsung Galaxy Note 8 and the Galaxy S7 edge for burn-in after putting them through a rigorous test. The Galaxy Note 8 had the best OLED panel on a smartphone before the iPhone X was launched, while the Galaxy S7 edge had the best OLED panel for a smartphone released in 2016. All the three phones used in the test feature panels manufactured by Samsung itself, with Apple further tweaking the panel on the iPhone X to its own liking.
For the unknown, a burn-in can occur when the same image is displayed for a long time on an OLED panel. The burned-in image will always be slightly visible which is more evident when viewing images with a light or dark background. Burn-in is a common issue with OLED panels, but on newer panels, burn-in can take a really long time to set in. Plus OEMs like Samsung and Apple take the necessary precautions using various software tricks to avoid burn-in from setting in early.
Coming back to the test from Cetizen, it shows that burn-in sets in on the iPhone X’s OLED panel after it continuously displayed a single image for over 510 hours. Burn-in on the OLED panels of the Galaxy Note 8 and Galaxy S7 edge started showing up much early, with the issue only becoming worse after 510 hours.
Now, in real life, no one is going to look at the same image straight for over 500 hours on their iPhone X. Nonetheless, the results are a good indicator of the excellent OLED panels used by Apple on the iPhone X. It should also bring a sigh of relief to iPhone X owners who are worried about the beautiful OLED panel on their device showing burn-in signs a few months down the line.
Finally, it also shows Apple’s engineering prowess. The company sourced OLED panels from Samsung and yet managed to beat them in performance thanks to its own tweaks and modifications.
