Ming-Chi Kuo is one of a handful of Apple analysts whose reports always warrant a second look, regardless of how strange they might seem at first blush. We’ve heard plenty of reports that the company is testing its own version of a foldable device, in its customary style of being fashionably late to the party, while also being the best dressed there.
It stands to reason that the company is experimenting with all sorts of takes on the form factor. While companies like Samsung and Huawei have made great strides since the first generation of foldable devices, one can certainly make the argument that no one has perfectly cracked the code just yet. The screen technology has improved a good bit in recent years — and so, too, has E Ink technology.
“Apple is testing E Ink’s Electronic Paper Display (EPD) for future foldable device’s cover screen & tablet-like applications,” Kuo reported on Twitter earlier today. “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.”
The last part is undeniable. One of E Ink’s biggest selling points is power saving. It’s a key part of the reason your Kindle’s battery life is rated in weeks, instead of hours. But the technology has traditionally had numerous drawbacks that have hampered mainstream adoption outside of a few select categories like e-readers.
Recent generations of E Ink’s electronic paper have added color and sped up the notoriously slow refresh rate and responsiveness. One imagines that there’s still a ways to go before Apple adopts such technology, even for a secondary, external display. Though, with the first of the company’s foldables rumored for a 2025 release (at earliest), perhaps that leaves enough time for the electronic paper technology to get up to speed.
As ever, one must take all of the above with a few grains of salt. It’s a long timeline, and even if the reports prove out, there’s a big gulf between testing and releasing. It’s also worth noting that these sorts of rumors have existed for nearly as long as the iPhone has. So, short term, maybe it’s best to focus on more attainable rumors like a USB-C iPhone.
