Digital Paper combines the simplicity of reading and writing on real paper with the convenience of digital features, including easy sharing across devices, searchable documents, and secure document encryption.
Writing and drawing feel as natural as on real paper, with the added benefits of highlighting and erasing with a flick of the pen, and turning the page without having to worry about keeping track of multiple sheets. The paper-like screen is glare-free, even in sunlight, and its high resolution displays clear, sharp text
A team of researchers with Nanjing University of Posts and Telecommunications, Nanjing Tech University and Northwestern Polytechnical University, all in China, has developed a new type of paper that can be erased and printed on multiple times. In their paper published in the journal Nature Communications, the group explains how they made their paper, how well it works and the ways they are looking to improve it.
The electronics giant is working on a phone with a flexible display that folds open into a 7-inch tablet, the Korea Herald reported Wednesday. It is expected to ship more than 100,000 units during the third quarter, sources described as familiar with the matter told the newspaper.
Korea-based Samsung had initially focused on a fold-in phone but abandoned the plan out of concern that people would find it inconvenient to unfold the phone every time they wanted to use it, the Herald reported.Samsung did not immediately respond to a request for comment.
E Ink has revealed what it’s calling the world’s largest commercially available active matrix ePaper module at CES 2017. QuirkLogic’s eWriter connected writer system has been combined with E Ink’s 42-inch ePaper display technology for the Quilla whiteboard.
Plenty of hype and pretty pictures, and a few cool surprises I’ve been going to CES since the days when press kits were made of actual paper (and you needed a Toshiba rolly bag to carry them all home). Over the years there’s one trend that’s becoming more and more apparent: Don’t expect many real details at the show. Prices? Availability? Yeah, right. Models beyond flagships and concept displays? Good luck. Information that’s not subject to change when the TV actually hits the market? HA! Heck, last year Samsung only showed one model of TV at CES, saving the real meat for mid-April.

E-ink displays may be easier on the eyes and less power-hungry than backlit LCDs used in most tablets and phones, but in the color department they’re still playing catch-up. However, this could change thanks to a new type of material developed at Chalmers University of Technology that is flexible, ultrathin and can produce the full color range of an LED-backlit LCD, but requires ten times less energy than a Kindle’s e-ink display.
Like a conventional e-reader screen, the material functions as a reflective display, so instead of being backlit like an LCD, the surface reflects the external light that hits it. Electrically conductive polymers covering the surface change how that light is absorbed and reflected, which allows it to recreate high resolution images and text. The end result is a material that’s less than one micron thick, flexible and extremely energy efficient.
“The ‘paper’ is similar to the Kindle tablet,” says Andreas Dahlin, lead author of the study. “It isn’t lit up like a standard display, but rather reflects the external light which illuminates it. Therefore it works very well where there is bright light, such as out in the sun, in contrast to standard LED displays that work best in darkness. At the same time it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.”
The Amazon Kindle is probably the least gadget-y gadget ever created. No one ever exclaims about its remarkable specs. It doesn’t need upgrading every two years. You just pick it up, turn it on, and read. It’s always felt that way too, even when the Kindle had a keyboard and nineteen buttons and weighed four hundred pounds.
It’s the black and white E Ink display that really sets the tone. It’s slow and sort of awkward to tap around on, but it’s simple. It doesn’t shine brightly the way your phone does, keeping your spouse up at night. Eventually, you stop thinking about the Kindle as a screen altogether. It’s just a book.
Electronic paper, as that display tech is known (E Ink is a trademarked term owned by the company named E Ink, the tech’s leading purveyor), has always been associated primarily with the Kindle and its ilk. But e-paper is about to be much bigger than e-books. These durable, easy-to-read screens are taking over the world, from billboards to price tags to the walls of your house.
We’ve been imagining this future forever: the all-screen worlds of Total Recall, Minority Report, Blade Runner, and other less-dystopian movies. Researchers have spent decades working out how to turn walls, floors, ceilings, and facades into touchscreens. The only way that works is if those screens are rugged as hell, don’t need much power, and can be used and seen in absolutely any conditions. Only one display technology checks all those boxes. Sooner than you think, e-paper is going to be everywhere. You might not even notice it’s there, and that’s the point.
Before we get too far, here’s a quick primer: An e-paper display is filled with really tiny ink capsules, which have electric charges. Some of the ink in each capsule is white, some is black. Using electrical fields, the display rearranges the ink to show different things on the screen. (When you turn the page on a Kindle, the resulting flash is just the ink rearranging itself.) That rearranging takes a very small amount of power, but when it’s done, it shuts off. Keeping an image on the screen doesn’t require any power at all.
An e-paper display obviously can’t do everything an LCD or OLED can. Those technologies are more colorful and vibrant. They refresh faster, and they’re much more responsive to touch—there’s no chance you’ll be buying an E Ink smartphone or television anytime soon. But not everything needs all that pizzaz, which is why gadgets of all shapes and sizes are already adopting e-paper screens. It’s all over the wearables industry, for one: the Pebble Time, the Withings Go fitness tracker, the Sony SmartBand Talk, the flexible new Polyera Wove Band. One of Timex’s high-end GPS watches has a color E Ink screen, using a technology called Mirasol. For these and other wearables, long battery life is much more important than tack-sharp resolutions and crispy colors.
Samsung is reportedly working on a bendable screen that could be used in new smartphones, fold into a smaller form factor and be durable enough for daily use. The real innovation and marketing will be convincing tech buyers they need a flexible screen.
A Bloomberg report noted that Samsung’s bendable screen could appear early next year in two smartphones. Samsung could also use the technology to create a phone and tablet 2-in-1 device. Samsung floated the idea in 2014 as well as 2013. Samsung already has its Galaxy S7 Edge device.
