It is said that Apple is preparing two different iPhone variants, one with a 4.7-inch and another with 5.5-inch display.
This extra screen estate will also require better, higher-res panels which will likely have resolution of 1704 x 960 pixels, up from the 1136 x 640 currently seen in the 4-inch iPhone 5, 5S and 5C. This in turn would be Cupertino’s answer to the full HD screen craze, but not as much to the emerging QHD display trend.
It is said that we’ll see the new iPhones launching at some point in September. Before that, we’ll get to meet the new iOS 8 at WWDC next month, and learn about Apple’s entrance to the mobile health & fitness market.
