Samsung Color E-Paper display could open the doors to new product designs

Posted on by

Samsung is a tech giant with its hands in many industries, but one of its biggest businesses is in making displays. These cover anything from TVs to laptops to smartphones to signage, supporting a variety of display technologies like LCD, LED, and everything in between. One kind of technology it has barely touched, however, is Electronic Paper Displays or EPDs, the same kind of eye-friendly, battery-efficient screens found on eBook readers. That is changing now, however, with Samsung dipping its toes into this market with a new Color E-Paper display that’s currently aimed at indoor signage and posters but could also be extended to new types of devices in the very new future.

Designer: Samsung

E Ink signage is becoming more common these days, especially as these electronic paper displays start to show improvements in color rendering. It’s not hard to see the benefits of the technology for this particular use case, since EPDs don’t use power to retain their image and use very little power when changing what’s on display. Although it is hardly the first of its kind, even for the tech giant, Samsung’s presence in this growing market is pretty much a stamp of approval from a brand that sells large TVs and screens for the same purpose of advertising in indoor signage.

The new Samsung Color E-Paper display seems to be really pushing the boundaries of the technology. The 32-inch has a QHD resolution of 2560×1440, though its real boasting feature is the 60,000-color gamut (six per pixel) which is quite high for a color electronic paper. This is thanks to the new E Ink Spectra 6 panel, the very same that flaunted artistic designs and images on the ASUS ROG Project DALI at Computex 2024 last week. This laptop concept utilizes a smaller panel that acts as a canvas for owners to customize the design of the laptop cover as they desire.

While the gigantic size of the Samsung Color E-Paper limits it to applications like signs and posters, it does make one wonder if Samsung will stop there. Its collaboration with E Ink could, in fact, lead to more devices with smaller screens, particularly in the eReader market that Samsung has never ventured into before. And with its close ties with Wacom, it could even add stylus support for these devices, potentially putting the likes of the Amazon Kindle and Kobo on notice.

ASUS Project DALI concept slaps a color E Ink display on the back of laptops

Posted on by

As much as laptop makers wax philosophical about the power of their hardware and the beauty of their screens, what most people will probably admire the most about their products will be the laptop covers. Like with smartphones, this is the most visible part of a laptop and, therefore, also the most expressive. You can almost tell a lot about the laptop owner from the design and stickers they have on their laptops or, conversely, from the lack of any embellishment. Unfortunately, there hasn’t been any easy way to cater to the varied tastes of laptop owners, at least until now. At Computex 2024, ASUS is showing off one of its latest concept designs that lets owners change the design of their laptop covers with a press of a key, and it won’t cost either power or money to keep changing it on a whim.

Designer: ASUS

You could, in theory, put a second LCD screen on the back of your laptop for a dazzling display of images or even captivating videos, but that would put a drain on your laptop’s battery, especially if you need to keep that cover display visible even when the laptop is closed and shut down. As with any problem involving power-hungry LCDs and OLEDs, the solution is using ePaper Display or EPD, like E Ink’s popular panels for eBook Readers. And wouldn’t you know it, E Ink has the perfect technology for that, and ASUS is slapping it on its Project DALI laptop concept to make laptops more personal without having to stick anything to it.

Although it’s primarily being used for signage installations, the E Ink Spectra 6 brings a touch of color to the eye-friendly and battery-conservative E Ink screen. It’s not going to match the vibrant colors of even the crudest LCD, but it has one very important advantage. Once you change the image displayed on it, it will no longer consume any power and can display that image for a long, long time. In other words, it’s perfect for a semi-permanent display that doesn’t change much, something like what the back of your laptop could have.

Project DALI puts this technology to offer an unprecedented level of personalization to laptop owners, something you can’t even imagine doing with stickers or skins. With ASUS’s special software, you can either select from a few preset designs or make your own, allowing you to express your tastes, interests, and personality the way you want it. Best of all, you can change it any time you want, and it will only cost you a bit of time and effort, not money from buying new stickers or energy from cleaning off those pesky adhesive residues.

ASUS Project DALI is hardly the first to put an E Ink display on the back of a laptop, as Lenovo also demonstrated a similar idea back in January at CES 2024. DALI, however, uses a newer Spectra 6 technology with higher color DPI, though the number of supported hues is, of course, still limited. Unfortunately, there is still no word on whether Project DALI will become an official ASUS product, but it’s bound to win plenty of fans once it does.

Bigme HiBreak E Ink smartphone takes another stab at eye-friendly mobility

Posted on by

As powerful and as helpful as smartphones have become, they have also become sources not only of distraction but also of poor health. Staring at screens all day is bad enough, but they can also affect our sleep if used late into the night. Unfortunately, it’s almost impossible for many people to detach from their phones or even reduce their use, so a few designers and manufacturers have tried to come up with alternatives like minimalist phones. eReader maker Bigme is proposing a different kind of answer, one that smashes an eBook reader and a smartphone in one pocketable design, creating a phone-sized E Ink device that is actually a functional phone.

Designer: Bigme

This isn’t the first time we’ve seen a phone-sized eReader. We reviewed the Onyx BOOX Palma a while back and found it to be quite capable as a pocket reader. But despite its phone-like looks, it’s technically a tiny Wi-Fi-only device. In contrast, the Bigme HiBreak can plug in a SIM card and connect to 4G LTE networks. Yes, 4G LTE speeds only, which is probably fine because the device’s screen won’t be able to catch up with the network speed anyway.

1

The HiBreak comes in two flavors with different 5.84-inch E Ink screens. One is a pure black and white screen like a traditional eReader, while the other supports a few colors at a lower resolution than black and white. Despite the advancements in E Ink technology, the ultra-slow refresh rates of these panels will take the fun out of scrolling and swiping through social media, which is probably for the best. What it offers, instead, is a gentler reading experience, especially if you’re the type who likes to read text-only documents on the go.

Of course, the Bigme HiBreak is a true smartphone, one that runs Android 11 on practically mid-range hardware. It does have Google Play support, so you can install any app available that supports that old OS version but don’t expect the experience to be as smooth as on a regular phone. On the flip side, that 3,300 mAh battery is going to last you for days rather than just hours. It has a 13MP main camera, more for “scanning” documents than taking pretty pictures, and a 5MP front camera for emergency video calls.

In terms of aesthetics, the Bigme HiBreak is truly a shrunken-down eReader, complete with wide bezels and a rather plain design. It’s almost like it’s intentionally uninspiring in order to cut down on your smartphone use unless that use is for lots of reading. But while it does solve the problem of eyecare, a device that runs a full Android stack with cellular connectivity won’t do any wonders for those distracting notifications unless you decide to ignore them since they won’t look that nice on the E Ink screen anyway.

Android tablet with monochrome LCD screen has a different fix for tired eyes

Posted on by

E Ink devices are transforming into more than just simple eBook readers. Some are even really just Android tablets in disguise, promising a more eye-friendly experience not just when reading books but also when surfing the Web, typing documents, or even scrolling through social media. These devices might feel like powerful e-readers, but they are a bit less impressive as Android devices exactly because of their most important feature: the slow E Ink screen. Out of nowhere, a new device has popped up promising a performance that’s almost on par with a modern Android tablet but with the same benefits of an E Ink screen, a promise that not only sounds too good to be true but will also cost you if you do decide to make the gamble.

Designer: Daylight Computer

What makes E Ink screens more eye-friendly is the fact that they traditionally don’t blast your eyes with light, especially blue light that’s been associated not only with eye strain but also with skewed sleep patterns. Unfortunately, even the fastest E Ink display is exponentially slower than even the slowest LCD screen, which makes it less comfortable to use for anything that involves constantly changing content, including typing quickly on the screen.

Daylight DC-1 is a new kind of tablet that tries to bridge those two worlds using a new “Live Paper” display that could be a special version of Sharp’s IGZO LCD screen. Unlike your typical display, it only shows shades of black and gray, but that’s not exactly what’s special about it. The claim is that, like ePaper screens, it doesn’t emit blue light, it can be viewed under direct sunlight, and is easy on the eyes. In the dark, it can use an amber-colored backlight that is still less straining than regular white light. Unlike ePaper screens, however, it can support a refresh rate of 60Hz, which is what most Android tablets can do at the bare minimum. Technically, it can go up to 120Hz, but that still depends on software support.

That software is a custom version of Android, so this device should be able to run any Android app, though there’s no word on whether it supports Google Play Store. the Daylight DC-1 definitely makes big promises, which is basically a watered-down, eye-friendly Android tablet experience. It can do almost anything, whether that’s typing a novel or scribbling notes with the included Wacom-powered pen. It really bridges the gap between regular Android tablets and this new breed of Android-powered E Ink readers.

There is, of course, a catch, and it’s a pretty big one. The device costs $729, and that’s only a pre-order for a device that’s still scheduled to ship later this year. That’s a pretty steep price coming from a brand that popped up almost out of nowhere. The theory does sound, well, sound, and the promises are definitely tempting, but these are very high stakes for a device that has yet to actually prove that theory out in the wild.

Dasung introduces a portable color E Ink monitor for eye-friendly computing anywhere

Posted on by

We have become very dependent on our computers, including the ones we keep in our pockets, but these powerful devices come with very harmful impacts on our health and lifestyle. Never mind the poor posture and negative social practices we develop through the use of computers and smartphones, even the very screens we look at affect not just our eyes but also our sleeping patterns. E-paper displays like E Ink have long been praised for their eye-friendly technology, but the old generation of these screens were so bad that they were good only for text that barely changes, like those in books. E Ink has thankfully evolved significantly over the years to the point that you can now have a portable monitor that combines E Ink and color to give your eyes a break when using laptops or smartphones.

Designer: Dasung

E Ink devices are getting larger and more complex as seen with the variety of color E Ink readers moonlighting as powerful Android tablets now available in the market. Despite their benefits in terms of comfort and power savings, E Ink screens are still significantly slower and show considerably fewer colors than even the most basic and cheapest LCD panel. That’s why selling an E Ink monitor for regular computer use sounds almost outlandish if not impractical, but that’s exactly the proposition that Dasung has been making with its line of Paperlike Color E Ink monitors.

The new 12-inch Paperlike Color takes that idea to a whole new level by making that E Ink monitor portable. It has a 12-inch screen that has an impressive 2560×1600 resolution, but only if you’re viewing black and white (or grayscale) images and text. The E Ink Kaleido 3 technology that it uses is able to display only 4,096 colors and usually at half the resolution, so it won’t exactly be mind-blowing. Of course, that’s the price to be paid for a screen that won’t tire out your eyes, at least not as much and as often as regular monitors.

The Paperlike Color (12-inch) also has other benefits, like an extremely light and slim profile made possible by having no battery at all. E Ink uses very little power, only when changing what’s being displayed, so it won’t drain your laptop or phone too much. Then again, if you will be using it like a regular monitor, that means content will be changing a lot, which would nullify this benefit and possibly produce visual artifacts. That said, companies that use color E Ink have strategies to address and improve the speed performance, but not to the same level as LCDs and OLEDs.

And therein lies the biggest question mark on this curious design, whether the benefits far outweigh the costs, both figurative and literal. Reading mostly static content and text is definitely more pleasurable, but it will only make sense if you use it on the side as a second monitor for your laptop. But then, it won’t really help you give your eyes much of a break if you’ll be using the laptop’s regular screen most of the time anyway. The E Ink monitor could be a nice external display for your smartphone, but that would run into the same limitations as color E Ink eReaders today. And with Dasung’s typical pricing, the Paperlike Color (12-inch) will probably be out of reach for many computer users, limiting it to a few enthusiasts who might find a place for it in their workflow.

Dual-screen E Ink reader doubles as a laptop for double productivity

Posted on by

Just like smartphones, laptops are undergoing a bit of change and experimentation with foldable, dual-screen, or even transparent laptops coming out of the woodwork. It’s only a matter of time before that trend makes its way to other devices, though there are signs of that happening in the e-book reader industry already. E-readers, as they are called, are breaking out of their shell, and some are even Android tablets that just happen to use e-paper displays. Compared to this unexpected design, however, those Android-powered E Ink readers sound almost unambitious, because this particular device actually puts together two E Ink displays to offer an almost literal book reader, a notebook, and a laptop all rolled into one.

Designer: LCFC (Hefei) (a Lenovo subsidiary)

Dual-screen laptops might not be new to our ears after the aborted Microsoft Surface Duo, the ASUS ZenBook Duo, and the Lenovo Yoga Book 9i. The idea behind this design is to bring the same dual-screen experience some users enjoy on desktops to the laptop without completely losing the advantage of portability. That use case might make perfect sense for a laptop that runs a conventional operating system with plenty of applications, but it isn’t as straightforward for e-book readers, even the ones running Android.

And yet, that’s exactly what the Gemini “Dual Screens Wisdom E-Ink Book” is trying to do, albeit with a slightly different focus. It connects two 7.8-inch E Inks screens using a 360-degree hinge that lets you fold it close like a book or fold it in the opposite direction completely to transform it into a tablet. In addition to reading, the device is designed to make it more natural to write down notes, possibly on what you’re reading. Note-taking is so central to the Gemini’s purpose that other features are framed in that perspective.

You can, for example, fold it half upright like a laptop for typing out notes. Of course, you’ll have to make do with an on-screen keyboard, but typing on an E Ink screen is notoriously awkward, uncomfortable, and inefficient, far worse than typing on a regular LCD or OLED display. You could potentially connect a Bluetooth keyboard, though that does lose the charm of being able to use this as a laptop. The Gemini also has a stylus you can write with, but the more interesting aspect of the pen is the detachable microphone module that you can use to record voice notes or even lectures.

The design of the Gemini is actually a bit peculiar thanks to an extended edge that’s thicker than the rest of the device. Not only is this where most of the electronics are housed, but it also seems to have controls like a dial and buttons, almost reminiscent of those display tablets for drawing. When using the Gemini like a laptop, you will be resting your wrist on this “bump,” but that will actually force you to reach further down to actually type on the E Ink screen, not to mention you risk triggering those buttons. There is no definite word yet on when and where the Gemini will launch, but it will happen sometime this year, though it remains to be seen whether it will elicit the same interest as dual-screen laptops.

3D-printed E Ink typewriter offers distraction-free writing with modern perks

Posted on by

Most if not all of us may have dreamed of writing some form of literature like a book or even a novel. It may be an adventure inspired by the latest bestseller that you read, a tear-jerking drama drawn from personal experiences, or even a technical matter intended to pass down knowledge to future generations. Although we still call it “writing,” the fact is that books today are all typed on some kind of machine or another, be it a computer or even an old-school typewriter, each with its own strengths and weaknesses. A computer, of course, delivers plenty of flexibility and convenience, but those also come at the cost of complexity and, more importantly, distractions. Distraction-free typing devices have been popping up here and there to cater to the needs of writers, but this particular design lets you create your own solution and, if necessary, even repair the digital typewriter yourself.

Designer: Vicente Cruz

There are quite a few distraction-free typewriter designs, but almost all of them have one important feature in common: they all use an e-paper display like E Ink. This usually monochrome screen is not just eye-friendly, it is also not that conducive to the colorful images and animations on the Web that distract us from our writing task. The technology is starting to catch up, though, but the advantages of E Ink still make it the perfect screen for such a purpose.

The Tapico Typer is a design that leverages that technology but also goes to the extreme when it comes to offering a distraction-free environment. You basically just have a keyboard with a somewhat small 4.2-inch E Ink screen centered on top. It doesn’t even have a battery, at least in this iteration of the design, so you’ll have to rely on an external power source like a power bank. It does have an SD card slot, however, which is the only way to get your files off the device since it has no network connectivity or even a USB data connection.

If that sounds extreme, it’s because it really is by design. The Tapico Typer is, interestingly, inspired more by a calculator than the old mechanical typewriter. It’s a single-function device that does only one thing but does it to perfection. It also means you have complete ownership of your content, free from subscription services and cloud storage. And, of course, there’s nothing to distract you on the screen, though the phone you place beside it could still steal your focus.

The digital typewriter is mostly 3D-printed and self-made, so it would be possible to follow the original’s design to make your own. Many of the components are available off shelves and there isn’t much soldering involved, so most of the work boils down to designing the chassis. A future plan is to include some internal power source or at least a way to use AA batteries that could last for months thanks to how little power E Ink displays consume. This also means that The Tapico Typerc can also be easily repaired, ensuring it will be your writing partner for a very long time.

Infinix E-Shift Color promises near-infinite phone design customization

Posted on by

Although we look at our phone screens almost all the time, it is really the back of our phones that gives them their personality. From the colors to the textures of their back even to the camera bump or bumps, this side of the phone is what other people see the most and, therefore, provides the most motivation for personalization and customization. A phone’s design, however, is permanent once it leaves the factory, and unless you put stickers or cases on it, its appearance will never change. Infinix, however, is presenting a solution to that design problem with a piece of technology that adds an almost literal splash of color to the back of your phone and changes that into a mesmerizing display of colors as often as you want, especially while it’s charging.

Designer: Infinix

Putting stickers or whatnot on the back of your phone is a sure way to ruin its future. Cases, on the other hand, are more temporary, but they not only add bulk but also limit your design options to what’s already available. Wouldn’t it be rad if you could change the color or even the colorful patterns on the back of your phone on a whim, similar to how you’d change your wallpaper every so often? Infinix’s E-Shift Color technology first unveiled at CES 2024 does exactly that, and it’s getting a little help from the same technology that powers your favorite e-book reader.

E-Ink Prism 3 is the latest iteration from the e-paper display expert that brings color to this traditionally colorless screen. In a nutshell, it uses electric charges to cause microstructures in the panel to change their color, similar to how an E Ink screen works. And just like an E Ink screen, it only uses power when changing colors, so displaying that static colored pattern will use almost no power to maintain that appearance, unlike a typical LCD or OLED screen. In practice, this means that you can change the phone’s back to a particular color and have it stay that way for as long as you like without draining the battery.

This opens the door to dynamic designs and personalization, with users picking the colors they want and having it change when they grow tired of it. It even has the possibility of rapidly animating these color changes while charging the phone, presuming you like to put it down flat on its face. Either way, it’s a fun experiment that will definitely appeal to the more youthful audience that Infinix targets, and it’s not hard to see how brands can also take advantage of this feature for marketing.

Because of E-Ink Prism’s segmented nature, the Infinix E-Shift Color is also limited to following certain patterns only, patterns that are also set in stone during manufacturing. It’s not like having access to a digital canvas where you create arbitrary pixel art images or animations. That could probably come in future iterations of the technology, but even this first attempt could very well be a huge selling point for people who want to make their phones look as alive and expressive as they are.

This portable E Ink typewriter reveals its guts to spirit you away to novel worlds

Posted on by

NaNoWriMo, short for National Novel Writing Month, has come and gone, but the joy and chore of churning out words never ends. Most people use a computer these days for writing any sort of content with words. Some might even use a smartphone to give their thoughts some form when a computer isn’t available. These devices are, of course, sufficient and practical, but that doesn’t mean they offer the best typing experience. They can become sources of distraction as well as cause of eye strain, both fatal for serious writers. Fortunately, there is now a class of devices that promise distraction-free typing, and this latest addition to that roster takes it up a notch with a design that will spark curiosity and flights of the imagination, hopefully, to better cajole those words out of your brain and onto a digital sheet.

Designer: Freewrite

The Freewrite Traveler is hardly a new gadget. In a nutshell, it is a portable digital typewriter that uses an eye-friendly E Ink screen for displaying the words you type. Unlike a laptop or phone, it doesn’t have any other function, which means there are no notifications or inessential features to distract you from the task of writing. It’s meant to deliver the joy of uninterrupted writing while still offering conveniences like a comfortable mechanical keyboard, saving files on the cloud, and a portable design.

The “Ghost” builds on this solid foundation and adds a design twist that, while not exactly necessary, could help lead your mind to new ideas. It takes inspiration from products that flaunted transparent or translucent shells, including old Game Boy models, the candy-like iMacs, or even Crystal Pepsi. As its name implies, the Freewrite Traveler Ghost sports a transparent shell that lets you take a peek at the electronics that make the device tick.

It’s admittedly gimmicky, but one shouldn’t underestimate the subconscious effects of such gimmicks on our creativity. Humans have always been interested in discovering what lies within, even if it consists of a jumble of wires. The play of light on the translucent white case also gives our eyes plenty of interesting visual points that, in turn, could help trigger the brain and spark new ideas. At the very least, it could offer a nice visual break while you stretch your fingers and arms after a long period of typing.

Granted, not everyone will be keen on spending a solid $600 on a device that does one thing and one thing only, but that limitation is also the very same appeal of the Freewrite Traveler. And when you’re a writer stuck in a rut or are easily thrown off your groove by distractions, every little bit counts to get you focused and inspired, even if it means staring at the indecipherable mess of modern electronics.

E-ink wall frame lets you read your newspaper’s front page

Posted on by

Believe it or not, there are still newspapers around and there are people (and not all of them old) who still prefer reading through this “old school” way of getting news. There has been a countdown to the demise of the printed versions of these publications but they are still alive and kicking. But we have to admit that there is so much new technology out there and these news organizations need to be able to adapt or eventually go the way of the dinosaurs.

Designer: Alexander Klöpping

The newest device that can help you consume news in a blend of digital and sort of analog way is Project E Ink which is basically a frame that you can hang on your wall. But instead of just having a static piece of art on this device, it will display the first page of the newspaper that you’re subscribed to so you can read the most important pieces of news for that day while drinking your coffee and staring at your wall. And from its name, it uses electronic ink.

The newspaper front page reader is a 32-inch screen which is the same size of an actual newspaper front page when it is unfolded. There are no other buttons on the device and it is not a touchscreen that you can swipe through. All it shows you is the front page of the newspaper and it will be refreshed every day. The battery can last for weeks since that’s one of the advantages of e-ink. It weighs just 17.6 pounds so there should be no danger of it falling off your wall.

At $3,050, it is an expensive piece of newspaper but should appeal to those looking to have a conversation and statement piece on their walls rather than as an actual way of consuming news. The creators also encourage people to subscribe to their favorite newspapers since they’re not really affiliated with any of the publications. You can subscribe to their online portal for content management at €60 annually.
