Abstract

Electro-optic, especially electrophoretic, displays are used in variety of architectural and furniture applications, including a tile (100) comprising an electro-optic layer (110) capable of changing the color of the file, front and multiple rear electrodes and a light-transmissive polymeric layer (102), the exposed surface of which is textured to provide a plurality of facets inclined to the plane of the tile (100), the rear electrodes being aligned with the facets. A variable color writable board is also provided.
