A definition of e-ink

Answer 1

'e-Ink' is short for Electronic Ink.

Actually it is not ink, it is a type of display film made by E Ink Corporation, and is used in electronic displays, such as E-books. The Motorola F3 cellphone also uses e-ink technology in its screen. 'Electronic Ink' works by using electronically charged micro-capsules suspended in a clear fluid, the polarity of the charge changing the appearance of these mini-points (pixels) from light to dark, or vice versa. The nature of e-ink and the relatively simply process involved means that the film can be applied to almost any material/surface, including glass, fabric and paper.
