Abstract
In the field of flexible displays there is a need for an electro-optic filament that is capable of being woven, knitted or crocheted. An electro-optic filament or fibre () includes an elongate core () extending lengthwise within a volume () of polarisable material; and an outer electrode member () overlying the volume (). The core () and outer member () are electrically conducting and connectable to electrical potentials to generate a radial field in the polarisable material. The outer member () is optically transmissive and/or transflective. The polarisable material () exhibits an optical effect such as a colour change, change in polarisation or change in reflectivity, when subjected to a said field or a change in a said field. The filament or fibre may readily be woven into eg. a fabric or a garment, using conventional textile processing machinery.
