Currently there is a shortage of the iPad mini with Retina Display (also known as the iPad mini 2). According to a report, Sharp has been cited as being the primary bottleneck. Sharp is reportedly having problems with production yields of the iPad mini with Retina Display.
“It’s unclear whether we’ll have enough for the quarter or not,” stated Apple CEO Tim Cook during Apple’s earnings conference call on Monday. The Apple iPad mini with Retina Display is believed to not be available until November. It can be rather difficult to create a display that supports a pixel-dense 2048 x 1536 resolution in 7.9 inches.
This is the same resolution that is in the larger iPad Air. Sharp uses a manufacturing process called IGZO to create the displays. LG Display is the largest supplier of displays for the iPad mini with Retina Display.
