On Tuesday LG Display, one of Apple's OLED suppliers for the iPhone, announced plans to invest $2.6 billion toward an existing OLED production line in South Korea.
The firm is predicting "tough" results for 2019 as it migrates more of its business away from LCDs, Reuters said. The company has been slower than chief rival Samsung in building out OLED capacity, forced to play catch-up now that Chinese competitors are intruding into its LCD business.
Indeed for a time Samsung was Apple's exclusive OLED supplier for iPhones, since it was the only company with enough capacity to handle the demand.
Apple likely needs LG to step up for several reasons — foremost that it's predicted to have two more OLED iPhones this fall, and go all-OLED in 2020. A June report claimed that LG was having production problems with iPhone panels, at least an initial batch.
Apple is also known to prefer having multiple suppliers per component, since it not only offers redundancy in the case of bottlenecks, but an opportunity to push parts costs down via competition and the fear that Apple will drop its orders.
