Abstract:
A method of making a gyricon, the method comprising:providing a plurality of substrate layers each having two substantially planar surfaces substantially parallel to one another, each layer having disposed therewithin a plurality of optically anisotropic elements,the elements of a first one of the layers comprising a set of elements each capable of modulating light to provide a first color selected from the group consisting of red, green, and blue, the elements of a second one of the layers comprising a set of elements each capable of modulating light to provide a second color selected from the group consisting of red, green, and blue, the second color being different from the first color,the elements of at least one of the layers comprising a set of elements each capable of modulating light to provide a third color selected from the group consisting of red, green, and blue and different from both the first and second colors, andaffixing the layers of the plurality to one another at their respective surfaces, so as to form a multi-layered assemblage, the layers in the assemblage being disposed substantially parallel to one another within the assemblage, adjacent layers in the assemblage being affixed to one another while being substantially unconstrained as to potential movement of their respective surfaces along a substantially planar interface therebetween.
