Reports about Apple’s efforts to develop its own display technology first surfaced back in 2018, and the company was originally aiming to introduce the technology in 2020. However, the costs and technical challenges associated with the development have caused delays. The company has reportedly spent several billion dollars on its development and is already testing the new screen on an update to the Apple Watch Ultra. It is also test manufacturing the screens in its facility in Santa Clara, California, though it may ultimately outsource its mass production.
