Abstract
An exemplary embodiment for an electric paper application is provided. The embodiment utilizes a disordered percolation layer for forming conductive islands on electric paper. The percolation layer is comprised of a disordered mixture of conductive and non-conductive particles that are attached to a non-conductive surface to provide conductive islands therein so that the electric charge can be appropriately held near the media plane of the electric paper.
