One of the major keys to Apple's success over the years has been the tight control it exerts over the components in its devices. Many things such as the iPhone's A-series processors and metal and glass chassis are designed in house, in order to meet the company's demanding specifications, before being sent to big manufactures such as Foxconn or TSMC. However, when it comes to displays, Apple has relied on what are essentially off-the-shelf components from third-parties such as LG (which makes the screen currently used in the Apple Watch) and Samsung (who makes the screen used in the iPhone X). Based on a report from Bloomberg, that could change.
