How E-Paper Works

• Comprised of two different parts
• Electronic ink or front-plane
• Electronics required to generate the pattern of
  text and images or backplane

Gyricon Example A Closer Look

• Consists of a single sheet of transparent
  plastic
• Each sheet contains millions of tiny bichromal
  (2 color) beads in oil-filed pockets

11

• Each tiny plastic bead can freely rotate within
  the plastic sheet
• The hemisphere of each bead has a different
  color and a different electrical charge
• When an electric field is applied to the
  backplane, the beads rotate, creating a
  two-colored pattern

this creates the image on the screen
