After recently suggesting that Apple could finally ditch the Lightning port for a USB-C port next year, renowned Apple analyst Ming-Chi Kuo has now come up with a new piece of information about Apple's rumored foldable device. Kuo says Apple is testing E Ink's energy-saving displays as an option for a secondary screen on its foldable device. Check out the details below.

Ming-Chi Kuo has had a good track record when it comes to Apple products. The analyst recently took to Twitter to report that Apple has begun "testing E Ink's Electronic Paper Display (EPD) for future foldable device cover display and tablet-like applications." That means a foldable Apple device is indeed in the pipeline. Apple is testing E Ink's electronic paper display (EPD) for future foldable devices' cover screen and tablet-like applications. Color EPD has the potential to become a mainstream solution for foldable devices' must-have protection/second screen thanks to its excellent power saving.— 郭明錤 (Ming-Chi Kuo) (@mingchikuo) May 17, 2022

Kuo says color EPDs from E Ink have the potential to become a standard option for secondary or cover displays on foldable devices. The cover displays on foldable smartphones show content at a glance such as music player controls, notifications, calendar updates and such. So using a color EPD for such a display makes sense, given the energy-saving features of e-ink displays.
