US Patent 7388572 Backplanes for electro-optic displays

A backplane for an electro-optic display comprises a plurality of pixel electrodes, and an adhesive layer disposed adjacent the backplane, the adhesive layer comprising a plurality of pixel regions disposed adjacent the pixel electrodes of the backplane, and at least one inter-pixel region disposed between two pixels of the backplane, the at least one inter-pixel region having at least one of a lower dielectric constant and a higher volume resistivity than the pixel regions of the adhesive layer.
