We’ve waited years for the iPhone Flip, and we’ll probably have to wait a few more, but when it does arrive, it might be significantly different from any other foldable phone on the market. This is because, according to Ming Chi Kuo, an Apple analyst with an excellent track record, the phone could include an E Ink cover display.
Electronic Paper Display (EPD) for usage on the secondary screen of a foldable phone, however it’s worth noting that even if Kuo is correct, the fact that Apple is testing something doesn’t necessarily imply the firm will utilize it.
Nonetheless, such a show could be beneficial.
This EPD technology is comparable to the screen on a Kindle in that it is designed to mimic the look of paper and is extremely low power, allowing the cover screen to be on all the time without draining the battery.
And, because it has a color screen, it goes above and beyond what all of Amazon’s Kindles now offer. For the reasons stated above, Kuo believes that this technology might be widely used for secondary screens on foldable phones, and that it may not be limited to Apple.
If Apple’s foldable device leverages this technology successfully, we can easily imagine other firms stealing the idea. Kuo also claims that Apple is testing an EPD with “tablet-like applications.” It’s unclear what it means, although it’s possible that Apple is also working on an e-reader or sketching tablet.
Analysis of the benefits and drawbacks of an EPD
While an EPD has clear benefits, the most notable of which is how gentle it is on a device’s battery, it also has certain drawbacks. If you’ve ever used an e-reader, you’ll know that they have extremely low refresh rates, making it difficult to get much work done.
The refresh rate can be increased in some circumstances, although this frequently results in ghosting. They are therefore perfect for reading books, but not for items that require frequent, quick input, such as animations and films.
That means an EPD cover display, like the cover screen on the Samsung Galaxy Z Fold 3, would probably not operate well as a full-featured smartphone interface.
However, it could be great as a less interactive screen focused on that, alerts, and the time, similar to the smaller cover display on the Samsung Galaxy Z Flip 3. If Apple employs an EPD on the iPhone Flip, the secondary screen will most likely resemble that of the Z Flip 3 rather than the Z Fold 3. Because of these constraints, even if other phone manufacturers follow suit, there will still be a demand for traditional second screens.
