A new report is suggesting that Apple has already been working on an upgraded iPad mini and that the new device will have a Retina Display. According to DoNews (via CultofMac), the company AU Optronics, the supplier of the screens for the current iPad mini, is working on preparing a display for the new device.
The display will apparently have four times the number of pixels as the current iPad mini, equating to double the pixel density and a 2048 x 1536 resolution. The iPad mini with Retina Display would essentially have a pixel density that is in excess of that found in the third and fourth generation iPad. The pixel density would actually be around 325-326 pixels per inch, which is the same as that found in the iPhone 4, 4S and iPhone 5.
Obviously the major challenge to this is battery life and maintaining the thin form factor of the current generation iPad mini. But you know what? Apple aren’t going to rush to release a device with these specs, predominantly because of the popularity of the iPad mini as it stands. You aren’t going to see an iPad mini with Retina Display for at least a year, if not two.
