Abstract:
1. A display comprising: a substrate having at least first and second portions having first and second optical characteristics differing from one another; a first fluid, the first fluid absorbing at least one wavelength of light, being colored by at least one of pigment particles, nanoparticles and quantum dots, and having a third optical characteristic differing from at least one of the first and second optical characteristics; a light-transmissive second fluid immiscible with the first fluid; and a first electrode adjacent the first portion of the substrate and a second electrode adjacent the second portion of the substrate, such that by controlling the potentials applied to the first and second electrodes, the first fluid can be made to assume a first position, wherein the first fluid substantially covers the second portion of the substrate, leaving the first portion uncovered, and a second position, wherein the first fluid substantially covers the first portion of the substrate, leaving the second portion uncovered.
