It's been rumored for months that Apple will launch two larger iPhone models this year, and now 9to5Mac is jumping in with a report on the new display resolution. If correct, we should see the iPhone 6 sporting a 1704 x 960 resolution. That's way up from the current 1136 x 640 resolution found on the iPhone 5 and iPhone 5s Retina displays, and would allow Apple to release the phones with a larger display while enhancing the Retina quality of its smartphones. No, it's not 1080p (that would be 1920 x 1080,) but it's close enough that at the rumored screen sizes of 4.7- and 5.5-inches, you'd be hard-pressed to notice.
The number we want to look at here is the pixels per inch (ppi), which will tell us how sharp the displays will be. 1704 x 960 at 4.7-inches results in a pixel density of 416 ppi. On a 5.5-inch iPhone, that drops a bit to 356 ppi. The iPhone 5 and iPhone 5s, comparatively, both have a 326 ppi display, so the new iPhone 6 models definitely will look better than the current devices.
iOS 8 won't be much different from iOS 7 in terms of the design and layout, so instead we can likely expect app icons that are sharper and larger on the home screen, and in-app elements to be clearer as well once developers get their apps updated for the new display. Of course, Apple will have its own first-part apps ready at launch.
