Some have speculated that Apple would maintain the current 326 ppi density, and bump the resolution to 1334 x 750. However, according to the report, Apple plans to triple the ‘base’ number of pixels on the iPhone screen from 568 x 320 and expand it to 1704 x 960. This would keep the current 16:9 ratio of the iPhone and keep the Retina branding.
Apple is preparing to make another significant screen adjustment to the iPhone. Instead of retaining the current resolution, sources familiar with the testing of at least one next-generation iPhone model say that Apple plans to scale the next iPhone display with a pixel-tripling (3X) mode.
