Per TechCrunch:
Another major feature, another big risk. Organic light-emitting diode, OLED, screens have been prized for their much better color and ability to “turn off” completely at the pixel level, leading to deeper blacks. But, especially in smartphones, they’ve also been plagued by poor off-axis viewing, rough color balance, issues being driven by onboard graphics cards and latent screen images that get “burned in” over time.
The
Google Pixel 2 is getting a drubbing currently for falling prey to a few of these issues. People who obsess over screens have been waiting to see whether the iPhone X is able to hurdle these issues and come up with a better implementation of OLED.
The answer is yes, mostly.
Apple’s version of an OLED screen is manufactured by Samsung,
but is not an off-the-shelf Samsung part. It’s a custom-built, diamond-pattern OLED array that was built to Apple specifications and driven by an Apple display driver. This screen is not comparable to screens found in Samsung devices on a variety of levels. You can like those screens just fine, I’m not arguing that, but this is absolutely not an implementation of a standard Samsung part.
The colors are bright and saturated, without blocking up — a big problem with red and magenta colors, typically. The True Tone screen means that you’re getting more accurate balance indoors and out as well. I could tell how my images would and should look even if I was viewing them under artificial light.
I hate to say it, but it makes the iPhone 8 Plus LCD look kind of like butt. I love it, even though it is flawed in one noticeable way.
The one area where this display falls prey to standard OLED gripes is in off-axis viewing. Apple tells me that it has done work to counter the drop-in saturation and shift to blue that affects OLED screens traditionally. I can tell you that, compared to other OLED screens, you have to get further “off of center” to see a real shift in color, holding the phone 30 degrees or more off of dead on. But it is still there. For people who share their phone’s screen or use it at odd angles a lot, it will be noticeable. On some phones, OLEDs go super blue. On the iPhone X it’s more of a slight blue shift with a reduction in saturation and dynamic range. It’s not terrible, but it definitely exists.
From the front-ish though? Wooof. It’s good. At a brightness of 640 nits, the view-ability is insane in the sun — much, much better than the iPhone 8 LCD. It’s hard to capture via photograph to be honest (though we tried), but in person you’ll be impressed by how easy it is to use in direct light. This helped a ton when walking back and forth from the interior of ride buildings to exterior walkways and looking at images while walking around under the molten, ever-present eye of a merciless star.
That, coupled with the True Tone tech makes images look better and brighter on the iPhone than any other Apple device, iMac included. It even makes pictures taken on other devices look better.
I haven’t been using the phone long enough to determine whether it is “burn-in proof” or whatever you want to call it, but Apple insists that it has done a ton of work to mitigate the problem. And I do use Twitter, with a static menu bar, a whole heck of a lot and see no burn in so far. That’s the best info I can give you besides that the Pixel 2’s burn-in started showing up pretty quickly.
