It added touch-screen capabilities, launched its first color display in late , and produced limited-color screens through The technology is considered a breakthrough, as each pixel contains all the pigments necessary to reproduce any color. This color technology is mainly aimed at the signage market. E-ink technology, which gained recognition primarily through the e-book reader market, has expanded to the manufacturing, architecture, and product labeling sectors, among others.

Bistability significantly reduces the power consumption and is a key reason devices using E Ink have such long battery life.
The larger ePaper screen, the more electronic power can be saved compared with the same size LCD screen. E Ink displays are referred to as "reflective displays. In an E Ink display, no backlight is used; rather, ambient light from the environment is reflected from the surface of the display back to your eyes.
Xerox has introduced plans to insert a memory device into the spine of the book, which would allow users to alternate between up to 10 books stored on the device. Just as electronic ink could radically change the way we read books, it could change the way you receive your daily newspaper. It could very well bring an end to newspaper delivery as we know it. Instead of delivery people tossing the paper from their bike or out their car window , a new high-tech breed of paper deliverers would simply press a button on their computer that would simultaneously update thousands of electronic newspapers each morning.
Sure, it would look and feel like your old paper, but you wouldn't have to worry about the newsprint getting smudged on your fingers, and it would also eliminate the piles of old newspapers that need recycling. Prior to developing digital books and newspapers, E Ink will be developing a marketable electronic display screen for cell phones , PDAs , pagers and digital watches. E Ink has already received financial backing from communications giant Motorola.
Electronic ink displays would have several advantages over current display technology, including:. E Ink unveiled its first product using electronic ink -- Immedia large-area displays -- in These large signs draw only 0.
E Ink said that in electronic devices, electronic ink would use 50 to times less power than liquid crystal displays because electronic ink only needs power when changing its display. For this same reason, a digital book can display the same text for weeks without any additional charge applied to it. Electronic ink can be printed on any surface, including walls, billboards, product labels and T-shirts. Homeowners could soon be able to instantly change their digital wallpaper by sending a signal to the electronic ink painted on their walls.
The ink's flexibility would also make it possible to develop roll-up displays for electronic devices. Another advantage electronic ink has over traditional computer displays is its readability.
It looks more like printed text, so it's a lot easier on the eyes. However, both Xerox and E Ink have to improve the resolution of their products for them to be viable in book or other small-print publications. Xerox has already made a display that has a dots per inch dpi resolution, which is more than twice the resolution of an average LCD display. Lucent's printable transistors should allow E Ink to increase the resolution of its products to resemble the resolution of a printed book.
E-Ink is a display technology that aims to replicate the appearance of ink printed on paper. As such, the vast majority of these displays are only capable of displaying black and white. Yes, the technology for colored E-Ink has been available for years, but it hasn't made a way into consumer electronics yet. The very first device to use an E-Ink display was Sony's Librie, an e-reader released only in Japan in It never had widespread adoption, due mainly to its expensive price tag and a file format with heavy DRM that made its ebooks expire in 30 days.
It wasn't until Amazon released the Kindle in late that E-Ink really took off. Like the Librie, it had an x pixel display capable of showing four levels of grayscale. The contrast wasn't amazing, but it allowed you to carry an entire library of digital books with you wherever you went, so it caught on. The latest Kindles -- the third-generation Paperwhite and the Voyage -- now have high-resolution displays with individual pixels that are almost indistinguishable to the human eye like Apple's Retina Displays and have 16 levels of grayscale, greatly increased contrast, and backlighting.
Of course, Kindles aren't the only devices to use E-Ink displays. There have been plenty of competitors over the years, including Sony, Barnes and Noble, Kobo, and Bookeen. Even cellphones have used the technology in the past. Before we continue, it's important that we distinguish between E- Ink and E- Paper. The two may sound the same, but there are some nuances that you need to be aware of.
E- Paper is any type of display which emulates the appearance of paper, and there are a few different technologies that come under this umbrella. As a rule, E-Paper displays are reflective rather than emissive, which means that they rely on external light sources rather than emitting their own light like LCD or OLED displays.
In other words, E-Ink is just one specific kind of E-Paper technology. The Pebble smartwatch is arguably the most popular example of an E-Paper display that doesn't use E-Ink.
Instead, it uses an extremely low-power LCD display with a reflective layer that looks like paper.
