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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
