Apple’s foldable device can use e-ink color displays – huge energy savings

Apple is exploring the use of e-ink display technology for its upcoming foldable devices, and is equipping a potential foldable iPhone and iPad with an Electronic Paper Display (EPD) as a cover or second screen.

According to According to analyst Ming-Chi Kuo, Apple is already testing color e-ink display technology to be used as a “future foldable display for screen and tablet-like applications.” This differs from the design used in Android foldables, such as the OLED cover display of the Samsung Galaxy Z Flip. However, using an e-ink screen consumes less power, which means that Apple’s foldable devices can have a long battery life.

It’s unclear whether e-ink’s EPD will be used as a smaller cover display on a foldable iPhone or as a full second screen. Kuo previously predicted that the Cupertino tech giant’s first foldable product will launch “at the earliest” in 2025, stating that we may not see a foldable iPhone, but rather a foldable iPad or a combination of the two popular devices. This could be similar in size to the 8.3-inch iPad mini, but with the foldability of the Samsung Galaxy Fold 3.

Apparently, Apple is “actively testing” a foldable nine-inch pixel-per-inch (PPI) OLED device between an iPhone and iPad. This means we could see a combination of an OLED display and a second color e-ink display.

Apple’s first foldable product has been in the air, as previous reports indicated we’d see some sort of iPhone Fold in 2023. This has now been pushed back, and Kuo thinks it might not be as simple as just a foldable iPhone. In February, Ross Young, the often-trustworthy CEO of Display Supply Chain Consultants (DSCC), claimed we could see a 20-inch all-display foldable MacBook — which when folded, could function as a MacBook with an on-screen keyboard, and as a iMac monitor when unfolded.

Young also states that we may not see Apple’s foldable device until 2025, so we still have a while to go before we see anything official. Speaking of foldables, what happened to the Google Pixel Fold? And is HP getting ready to present a 17-inch foldable OLED laptop? Stay tuned for more.
