iPhone 6 Displays Demystified ⇥ paintcodeapp.com

If you followed the rumour blogs prior to Tuesday’s Apple event, very little about the iPhone 6 and 6 Plus came as a surprise to you. The one thing that is surprising is the way in which the 6 Plus handles scaling. It is, as many predicted, a 1,242 × 2,208 pixel interface, but the display itself is 1,080 × 1,920 pixels, so the interface is scaled down to fit. Pixel-perfect scaling of @2x interface elements was already going to be a challenge, but the display itself is not pixel-perfect. It’s “better” in a numbers game against the iPhone 6 and it may look alright at 401 pixels-per-inch density, but that feels like a significant compromise.
