Sharp, LG and Japan Display Inc. (Sony/Hitachi/Toshiba) supply the Retina display. This will be a cash boon for these three companies. Samsung supplied most of the displays for the iPhone 4 but apparently no longer. Apple accounts for 8% of Samsung's total revenue.
Samsung supplies the iPhone 5's new A6 processor.

I would not put a fork in Sharp just yet. I would not be surprised that this forward looking data is partially why Sharp's main banks are willing to lend it the massive amounts of money that it needs to borrow.
