In the past couple of years, several reports claimed that China's Hon Hai Precision Industry, or Foxconn, is starting to develop OLED displays, with the latest one being a rather confusing one about an 8.5-Gen LTPS fab in Taiwan.
An article from Japan now says that Foxconn is developing 5" flexible OLED displays, with first samples shipping by 2016, and limited low-scale production slated for 2016 as well. Foxconn is one of Apple's major suppliers.
In 2013, by the way, Foxconn was said to establish an OLED R&D center in Japan with an aim to start AMOLED panel production in 2015. This R&D center was supposedly being launched in collaboration with Sharp's Sakai Display Product (SDP) - which is jointly operated by Foxconn and Sharp.
