LG Display Co. will reportedly supply between 2 and 4 million organic light emitting diode (OLED) displays for  Apple's iPhones.

This number is small relative to Apple's phone sales, Bloomberg notes, but solidifying LG as an OLED supplier would make Apple less reliant on Samsung, the sole source of displays for the iPhone X and its main rival in the smartphone market. The expense of using Samsung to supply OLED screens has been linked to the iPhone X's $1,000 starting price and its lower-than-expected sales.
