The iPad mini currently has a pixel density of 163 ppi (pixels-per-inch), which is the same as the iPad 2. However, Apple is reportedly working on a second gen iPad mini which is slated for release later this year. New rumors are now beginning to circulate that the next generation iPad mini will carry a 324ppi Retina Display.
According to news service BrightWire, AU Optronics is managing the production of the iPad mini and that the new screen on the device will be 2,048 by 1,536 pixels, which is four times as many pixels as the current iPad mini. Rumors about the iPad mini receiving a Retina Display have been around since the introduction of the device in October.
With a Retina Display on the same 7.9” screen, developers would only need to update the apps with high resolution artwork. During the introduction of the iPad mini, Apple noted that applications developed for the full sized iPad would be able to run on the 7.9” screen without being reworked. However, it appears that some apps do run letterboxed, similar to the transition from 3.5” screen of the iPhone 4S to the 4” inch screen of the iPhone 5.
Apps running letterboxed still take advantage of the Retina Display as they do not take up any more space than the device that it is developed for. Alongside the iPad mini’s thin bezel, majority of users won’t notice a huge difference when the device does letterbox videos or apps.
The rumored Retina Display, coming in at 324ppi would be 2 pixels short of matching up the current iPhone 5 display, which is an impressive feat when noting the larger screen size of the iPad mini. It is unclear how Apple plans to incorporate the Retina Display and retain the same form factor of the device without sacrificing the legendary 10 hour battery life.
