Abstract:
A gyricon sheet comprising:a) a substrate having two opposed surfaces wherein one of the surfaces is a viewing surface, andb) a collection of optically anisotropic light modulating elements capable of being made rotatable wherein each element is capable of producing two observable aspects to an observer favorably situated to observe the viewing surface wherein one aspect is being substantially optically transparent and the other aspect is associated with a component color wherein at least some of said elements are associated with a first component color, at least some of said elements are associated with a second component color different from the first component color, and at least some of said elements are associated with a third component color different from both the first and second component colors, and wherein at least some of the elements associated with each of the component colors are uniformly and randomly distributed in a substantially single layer with respect to at least a portion of the viewing surface.
