The next-generation iPad mini will get a display with 324 pixels per inch, says Chinese site My Drivers. The information stems from sources at Taiwanese Apple suppliers, who say that AU Optronics is piloting production of the new tablet. The hardware is expected to use a 2048x1536 display resolution, the same as the fourth-generation 9.7-inch iPad, despite having to compress that detail onto a 7.9-inch screen.
