This year, reports from Apple’s supply chain have long claimed that the company is looking to diversify its suppliers, especially for display panels. Apple plays a pretty tough supplier game and often prefers to have all the power in a situation, particularly with smaller companies who do not have a large customer base.

To that end, for the 2018 iPhone lineup, Apple reportedly turned to LG for fulfilling the OLED panel requirements of the larger iPhone X(s) Plus. To recap, the rumor mill believes that Apple will launch three smartphones this year.
