  • Rumors continue to swirl about a foldable Apple device.
  • Ming-Chi Kuo says the company is testing an Electronic Paper Display from Chinese company E Ink.
  • It could be used as the "cover" or secondary display on a folding device thanks to its power efficiency.

A new report claims that Apple is testing an Electronic Paper Display from E Ink as a possible solution for the cover or secondary display on a future foldable iPhone or tablet.

Apple supply chain insider Ming-Chi Kuo Tweeted Tuesday:

Apple is testing E Ink's Electronic Paper Display (EPD) for future foldable device's cover screen & tablet-like applications. The color EPD has the potential to become a mainstream solution for foldable devices' must-have cover/second screen thanks to its excellent power-saving.

According to Kuo, Apple would use E Ink's EPD as the "cover" or second screen on a foldable device thanks to "its excellent power saving." This would indicate that Apple is considering using an external display on its foldable that would be able to depict information on the exterior of the device while it was closed, perhaps like the always-on display of the Apple Watch Series 7.

It was reported last week that Apple trying to develop its own version of the OLED technology used in the Galaxy Z Fold 3 for a future folding iPhone. Kuo stated back in April that Apple was "actively testing" a 9-inch foldable device that would launch in 2025 "at the earliest", stating the device was either a foldable iPad or a hybrid of an iPhone and an iPad.

Apple's foldable is still a few years away, so don't expect the iPhone 14 or any of its other best iPhones to fold for at least a couple more years.
