What Is Electrophoretic Ink (E Ink)?

Add some softness and dimension to your device with E Ink's proprietary display tech.E Ink is a brand name for the electrophoretic effect in electronic paper. The technology uses charged pigments and transparent electrodes to reflect light and make images that resemble ink on paper. E Ink displays are used in e-readers, such as the Amazon Kindle, Barnes & Noble Nook, and other portable electronic devices. The distinctive contrast and low power usage of E Ink displays make them ideal for use outdoors and in bright light conditions. These displays don't contain any light-emitting components. They require an external light source to display an image. E Ink is a high-tech way to make electronic paper, allowing it to retain text without power. Tiny capsules called microcapsules, containing two different particles, are applied to form to create the image. When an electric field is used, the negatively charged black particles go one way, and the positively charged white particles go the other, creating an image that appears like a newspaper or book. Here's a truly crazy idea, let's dump all our electronic gadgets into a big bucket of water, right? No, silly. The E Ink display we love so much allows for this. It has millions of tiny microcapsules, each individually filled with a dye solution. These microcapsules are arranged on the surface of a display so that each side is exposed to the electric field, then forms the text or graphics you see before you. It all started in the late 1990s when E Ink was introduced. It could only generate a black-and-white display, which meant "no fun" for reading or other activities. E Ink is still used today, but with color filters on top of the show, we can now use our e-readers to watch videos and read books in color. E Ink displays are easy on the eyes and don't need constant refreshing. That means they consume very little power, which makes them an excellent choice for reading ebooks or news reports.
