What’s this? Provide-chain analyst extraordinaire Ming-Chi Kuo has urged that Apple’s investigating E Ink shows for future foldable iPhones. Now, Apple certainly investigates a number of issues–and most of them by no means make it throughout the end line to grow to be actual merchandise.
However as a long-time admirer of E Ink as a expertise, I’m excited concerning the chance that Apple may use it in future units. E Ink is a distinct segment expertise with some very actual limitations, but it surely’s additionally bought some big benefits.
What’s E Ink?
E Ink is a show expertise that’s essentially completely different from LCD, OLED, and different show applied sciences. It really works through the use of electrical energy to set tiny capsules of pigment to point out or cover. The result’s a floor that works kind of like conventional ink on paper, therefore the identify.
Since an E Ink display solely makes use of energy when the display is being rewritten, it’s nice for functions during which the show doesn’t replace fairly often. Most individuals know E Ink shows from e-readers like Amazon’s Kindle and Rakuten’s Kobo. These units can have very lengthy battery lives as a result of they’re usually solely utilizing battery energy if you flip the web page.
E Ink crops up in just a few different areas, too. There’s quite a lot of digital signage (suppose worth tags on grocery store cabinets) that’s beginning to use E Ink–one other case the place the textual content stays fastened more often than not, so there’s little or no energy draw. (My favourite E Ink venture could also be this one which resembles a flattened unique Mac.)
I like E Ink as a result of it’s simpler on the attention and feels pure in pure mild. Nonetheless, the expertise has a number of liabilities which have led to it not getting used extensively. For starters, it doesn’t emit mild. In daylight, E Ink screens are past reproach, however in darkness, they’re unreadable. (To compensate, most e-readers now include a built-in ring of LED lights across the display.)
E Ink Gallery 3 was launched in April, providing an improved coloration gamut and quick refresh charges, but it surely’s nonetheless too sluggish for multimedia.

Worse is the sluggish refresh charges of E Ink screens. The refresh charge has elevated over time–on state-of-the-art shows it’s now 350 milliseconds–but it surely’s nothing just like the ultra-fast refresh charges of pc shows. Meaning it’s inappropriate for animation, video, and just about any interface designed for fast animations. (Final yr I reviewed an E Ink Android pill, and attempting to make use of the Android interface at such a low refresh charge was painful.)
E Ink shows additionally don’t supply the ultra-high resolutions of contemporary Apple shows. And whereas E Ink shows have begun to help coloration (after years of solely supporting shades of grey), the standard is simply now getting as much as par, and the refresh charges are nonetheless fairly sluggish.
The place Apple may use E Ink
According to Kuo, Apple is testing E Ink “for future foldable machine’s cowl display & tablet-like functions.” It is sensible. Foldable units usually fold inward to guard their shows–leaving an outer floor devoid of data. To counteract that, phone-makers have been including supplementary “outer screens” to do issues like show the time and fundamental info widgets whereas others have full-sized OLED shows that clearly use a number of battery life.
Because of its ultra-low-power profile, an E Ink show can be a fairly good match for a canopy show. (Consider how the always-on Apple Watch show has a low-power mode that doesn’t replace the show fairly often, making issues like second arms disappear with the intention to save energy.) With a coloration E Ink exterior show, Apple might show the time, notifications, and even widgets on a tool’s outer display.
However auxiliary E Ink shows aren’t essentially only for foldable telephones. Think about a future MacBook that included a low-power E Ink display on the skin in order that you possibly can see notifications and different fundamental standing info with out opening it.
E Ink expertise may additionally enable the creation of some fascinating equipment, particularly when coupled with one thing just like the Good Connector port on the iPad, which might switch information and provide energy. For instance, think about an iPad sensible cowl that included an E Ink Show (shoutout to reader Adam L. for this concept), to show widgets, standing info, and perhaps even static shows from apps, all of which might be seen even in vibrant daylight. Alternately, how about an iPhone case that included an E Ink show on the again for standing widgets?
E Ink might be by no means going to be a mainstream show expertise. The OLEDs and LED/LCD shows of the world present excessive resolutions and refresh charges that may’t be beat. However there are various niches that E Ink can serve nicely. I’d like to see Apple deploy E Ink’s distinctive traits in some inventive methods.
