SlashGear reports on an article [Google translation] from Chinese site DoNews claiming that Apple's iPad mini display partner AU Optronics has a Retina-resolution display in the pipeline for the next generation of the device, which is expected to be launched next year. There has been considerable discussion about how quickly Apple might be able to move to a Retina display in the device, and today's report suggests that Apple may not have to wait several generations to make the jump as it did with its other iOS devices. A separate report from MENAFN claims that AU Optronics will be adopting indium gallium zinc oxide (IGZO) and Gate IC on array (GOA) technologies in order to reach the Retina resolution in a thin design required for the iPad mini. One major issue with both of the reports is confusion over the pixel density on these panels. Both reports claim that the Retina-level iPad mini display would carry a density of 497 pixels per inch (ppi), whereas such a display would actually have the same 326 ppi seen on the last several generations of the iPhone. MENAFN also misstates the density of the full-size iPad's display as 326 ppi, while DoNews correctly lists it as 264 ppi.
