A type of display used in e-readers.
E Ink displays only use power when changing the contents of the display, which allows a device with an E Ink display to have an extremely long battery life.
E Ink displays can be read in bright sunlight like a printed book.
E Ink displays are slow to refresh, which makes them impractical for displaying video or animation.
E Ink displays are typically black-and-white, but colour E Ink displays are entering the market.
Technically, E Ink is a brand name used by E Ink Corporation, but the term has come to be used for all similar displays.
