Topics: Flat Panel : E-Ink

E-Ink stands for electronic ink, a type of display device with dramatic benefits over traditional media:1) Reflective: emits no light, for low power use.2) Non-volatile: uses no power except to change image; when power is off, the image remains.3) Low power use: reflective and non-volatile.4) Low mass: very thin with low density materials.5) Size range: tiny to several meters across, all tested in public.6) Flexible physically: can bend somewhat without breaking.7) Low cost: made of inexpensive materials, with no light emitters.Operating principle: uses reusable 'paper' and magnetic or electrically charged 'ink' (bichromal beads) to display information. Electronic paper can be magnetized to show changing content, and then re-written for the next use.
