Abstract
A display includes an encapsulated display media, a rear electrode, and a movable electrode. The encapsulated display media comprises a plurality of capsules, each capsule comprising a plurality of particles dispersed in a fluid. The display media has a first surface and a second surface. The rear electrode is disposed adjacent the second surface of the display media. The movable electrode and the rear electrode apply an electric field across the display media.
Claims68
A display comprising:
- an encapsulated electrophoretic display media comprising a belt loop and containing a plurality of capsules, each capsule comprising a plurality of electrophoretic particles dispersed in a fluid, the display media having a first surface and a second surface, the belt loop adapted to loop around at least a pair of rollers;
- a rear electrode disposed inside the belt loop and between the first surface and the second surface of the display media;
- and
- a movable electrode, in conjunction with the rear electrode, applying an electric field across the display media.

A method for creating an image on a display comprising the steps of:
- a) providing a display including an encapsulated electrophoretic display media comprising a belt loop and containing a plurality of capsules, each capsule comprising a plurality of electrophoretic particles dispersed in a fluid, the display media having a first surface and a second surface, and a rear electrode disposed inside the belt loop and between the first surface and the second surface of the display media;
- b) placing a movable electrode adjacent the first surface of the display media;
- c) applying an electric field across the display media through the movable electrode and the rear electrode, thereby creating an image on the first surface of the display media;
- d) looping the belt loop of the display media around at least a pair of rollers;
- and
- e) rolling the rollers to cause the display media to roll.
