Apple allegedly testing electronic paper displays (EPD) for upcoming foldable devices
Market analyst Ming-Chi Kuo has a decent track record when it comes to Apple-related leaks, but, as of late, quite a few of his reports missed the mark, so a healthy dose of salt could be in order for his most recent tweet claiming that Apple is testing electronic paper displays (EPD) for foldable iPhone models.
Even though foldable screens have been a thing for a few years now, Apple apparently still views this technology as relatively immature and it is really taking its time to refine its first foldable devices. Apple probably realizes that it will not be able to bring too much innovation on the foldable screen side, but it will surely look to set its devices apart with technologies that no other brand is currently offering. These technologies may very well include electronic paper displays, as reported by Kuo.
We should not expect EPDs to replace OLEDs, however. As Kuo points out, color EPDs with E Ink have the potential to see mainstream adoption by becoming the technology of choice for cover / secondary screens due to their superior energy efficiency. The main displays will still use OLEDs, and Kuo believes that the first foldable from Apple could feature a 9-inch screen. Initially believed to launch in 2023, this foldable model is now rumored to have been postponed to 2025.
Apple may look to launch medium-size and large size devices like tablets and phone-tablet hybrids with foldable displays first, then integrate the technology on small devices like iPhones. Apple may also consider implementing EPDs in its popular wearable devices.
