In January 2018 it was reported that LG Display is in the final stages of its discussions with Apple, and the Korean OLED maker expects to supply 15-16 million flexible OLEDs to Apple in 2018 (LGD will supply Apple with 6.5" AMOLEDs for its 2018 large iPhone OLED variant).
It was later reported by the Wall Street Journal, however, that LG Display may not be ready to produce these OLED displays in time for Apple. Today Bloomberg reports that LGD will supply OLEDs to Apple this year, but only 2-4 million panels (out of about 70 million panels) - with the rest supplied by Samsung Display of course. Bloomberg did not detail whether LGD will supply Apple with the 6.5" OLEDs or the 5.8" ones.
Apple was never happy with having a single supplier for its OLED displays, and it hopes that next year LGD will be able to supply more OLED panels, and present a real competition to Samsung Display.
