A 'paper look-alike' display comprises pixels formed of dielectric particles suspended in a non-conducting liquid. By applying a voltage to electrodes the particles may be switched between positions in which they are stored in vertical columns normal to the surface of the pixel and have no effect on the color of the pixel, and a position in which they occupy a major part of the surface area of the pixel and influence the color of the pixel accordingly.

Display apparatus

There is described an electrorheological fluid comprising particles of a composite material suspended in an electrically insulating hydrophobic liquid. The composite particles are metal salts of the form MMTiO(CO)where Mis selected from the group consisting of Ba, Sr and Ca and wherein Mis selected from the group consisting of Rb, Li, Na and K, and the composite particles further include a promoter selected from the group consisting of urea, butyramide and acetamide.

Electrorheological fluids

The present invention relates to planar materials having bandgap properties. The materials are formed by depositing conductive fractal patterns on a non-conducting substrate. The bandgap location(s) are defined by parameters including the number of fractal levels, and the dimension of the fractal mother element. The bandgaps can also be actively controlled by injecting current into the conducting pattern.
