Apple Foldable Phone Could Feature E-Ink Cover Display [Update]

Last Updated on May 17, 2022 by Anu Joy

Today, Apple analyst Ming-Chi Kuo shared that the iPhone maker is testing a color e-ink display technology. This tech could be used in upcoming foldable devices such as the iPhone and iPad. Kuo adds that e-ink could be a good low-power solution for the outer-most display.

This approach is quite different from that employed by the outer displays of Android foldables. For instance, the Samsung Galaxy Z Fold sports a 6.2-inch AMOLED cover display, resembling a regular smartphone when folded. Since the content isn’t static, using an e-ink display makes no sense in this case.

However, if Apple decides to opt for the clamshell design reminiscent of the Samsung Galaxy Z Flip, an e-ink display appears to be a valid solution. The Galaxy Z Flip 3 comes with a 1.9-inch OLED cover display, which simply shows the time and notifications. As e-ink only consumes power when the display is being updated, no power is required to show static content. This will be more energy efficient compared to OLED or LCD.

Kuo suggests that Apple’s upcoming foldable device will have an e-ink outward-facing display. This could function as a static screen that could show notifications to users who just want to check their device without having to unfold it. A major advantage of this feature is that it will consume less power.  

Do note that Apple has not revealed any details about a possible foldable device. So, take these rumours with a pinch of salt. Last year, Kuo suggested that the iPhone maker could launch a foldable iPhone in 2023. But display analyst Ross Young begs to differ, and claimed that the firm may launch its foldable phone in 2025.

Update: Kuo Clarifies That Apple Is Testing E Ink Company’s Display Technology For Foldables

Kuo tweeted that he was referring to E Ink, a company that specialises in ePaper technology, in his previous tweet. Apple is reportedly testing the firm’s Electronic Paper Display (EPD) technology for its upcoming folding devices such as iPhone and iPad.
