Abstract

Woven material comprises a first set of electrically conductive elements and a second set of hollow fibres, the hollow fibres containing electrophoretic material. The electrically conductive elements may be substantially perpendicular to the hollow fibres. A third set may also be present, for example, a set of insulated electrically conductive elements (as shown in FIG. 1), substantially parallel to the hollow fibres, or a set of electrically conductive elements, being contained within the hollow fibres, or another set of hollow fibres, also containing electrophoretic material, being substantially perpendicular to the original hollow fibres. A display device comprising the woven material is also described which further includes electrical connectors connecting to the electrically conductive elements and circuitry connected to the electrical connectors and driving the display device.
