Apple has increased its expenditures on research and development recently, spending $3.75 billion on R&D during Q4 2018 compared to just less than $3 billion during Q4 2017—a year-over-year increase of $750 million. One area of technology where this investment may pay off will likely be flexible screen technologies. This includes innovations in elastic substrate layers serving as the circuitry for future iPhones and the continuing development of organic light emitting diode (OLED) technologies with flexible characteristics.
