Developer Hamza Sood has discovered frameworks within iOS 8.1 beta 2, which contain ‘3x’ image assets for iPad interface elements that suggest the new iPads may come with higher resolution displays.
This won’t come as a surprise as iPhone 6 and iPhone 6 Plus introduced last month come with higher resolution Retina HD displays. According to Apple, the new Retina HD display technology deliver higher contrast, dual‑domain pixels for more accurate color at wider viewing angles, and an improved polarizer, which gives a clearer view when you’re wearing sunglasses.
The new display technology should also allow Apple to make the new iPads thinner. The leaked iPad Air 2 unit suggests that it could be as thin as 7mm (1st generation iPad Air is 7.5mm in thickness).
iPhone 6 comes with a 4.7-inch Retina HD Display with 1334 x 750 resolution and pixel density of 326 pixels-per-inch (ppi), and the iPhone 6 Plus comes with a 5.5-inch Retina HD Display with 1920 x 1080 resolution and pixel density of 401 pixels-per-inch (ppi). In case of the iPhone 6 Plus, it actually scales down the 2208 × 1242 interface to fit the 1920 × 1080 display. It remains to be seen what resolution the new iPads will sport, if they do come with Retina HD.
