Abstract:
1. A display comprising: a substrate; a first fluid disposed adjacent the substrate, the first fluid absorbing at least one wavelength of light; a light-transmissive second fluid immiscible with the first fluid; at least one electrode for applying an electric field to the first fluid; and a concealment member spaced from the substrate and formed from a substantially opaque material, such that, in the absence of an electric field, the first fluid covers a first area of the substrate, but that upon application of an electric field to the first fluid by the at least one electrode, the first fluid moves to a second area smaller than the first area and substantially confined between the concealment member and the substrate, so that the concealment member substantially conceals the first fluid from an observer viewing the display from the opposed side of the concealment member from the substrate.
