According to a new report form Nikkei, Apple decided to adopt OLEDs sooner than expected - in the 2017 iPhone. Apple previous aim was to use OLEDs no sooner than 2018. Nikkei further says that Apple started talking to both Samsung Display and LG Display in December 2015 regarding a supply deal - that may reach $12 billion in total orders.
This is an interesting claim. The iPhone 7 will be released in 2016, so the 2017 should bring us the "iPhone 7s" - which usually means no real design changes. But it is highly likely that Apple will choose to go with a flexible OLED - maybe curved on the edges like Samsung's edge phones. Maybe this will be a new "premium" iPhone model (iPhone edge?).
Samsung's OLEDs are considered the best mobile displays on the market - maybe Apple is paying close attention to such reports and that's why the need to adopt the technology sooner than expected. Perhaps SDC's recent decision to double the capacity of its A3 flexible OLED line is related to Apple's move...
