AU Optronics Developing Retina Display for Second-Generation iPad Mini?
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.
It is said that ultrahigh resolution can not be developed without the technology of indium gallium zinc oxide (IGZO), and the technology of Gate IC on array (GOA) is also indispensable since the next-generation iPad Mini will have an ultra-narrow frame. The technology of GOA helps save the room of IC on the rim and narrow the frame of the screen to the largest extent.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.
Speaking of the progress of the development of iPad Mini, AUO claimed that it had solved the problem of yield and there would be no light leak as existed before. The company would ship the products in large scale in the fourth quarter.
