Abstract
The presently described embodiments provide electric paper, in one form, that is bisymmetrical, both sides of the paper have the same thicknesses of mylar layers and the same thicknesses and patterns of ITO islands. In another form, a disordered layer of conductive particles, non-conductive particles and display elements has the same percolation threshold throughout, and thus is bisymmetrical. In either form, in a system for printing all asymmetries in the printing process are transferred to the printhead, just like in conventional ink printers and paper. As a result, both sides of the electric paper are equally capable of being printed on, just like conventional paper, and the electric paper has the same flexural properties when flexed in a concave or convex manner, just like conventional paper. This construction has the additional practical advantage that there is no longer any need to ensure the electric paper is oriented 'right side up' before printing on it. These improvements all make electric paper more paper-like in feel and use.
