What is E Ink?
E Ink is the creator of electronic ink — the optical component of a film used in Electronic Paper Displays. Although futuristic-sounding, electronic ink is actually a straightforward fusion of existing knowledge of chemistry, physics and electronics to create this new material. It's so much like paper, it actually utilizes the same pigments used in the printing industry today.
Electronic ink is made up of millions of tiny microcapsules, about the diameter of a human hair. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white or black at that spot.
What is a Bistable Display?
E Ink's technology is commonly referred to as "bistable". What does this mean? Bistable means that the image on an E Ink screen will be retained even when all power sources are removed. In practice, this means that the display is consuming power only when something is changing.
For example, when reading on an eReader, power is only needed when turning to a new page but no power is consumed by the display while reading the page.
This is most noticeable when an eReader goes into sleep mode yet there is still an image being displayed. By contrast, with a traditional LCD, the display is needs to be refreshed around 30X per second, regardless of the whether anything new is being displayed. Bistability significantly reduces the power consumption of displays using E Ink and is a key reason eReaders have such long battery life.
