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.
