Abstract
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.

A backplane for an electro-optic display, the backplane comprising 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.
An electro-optic display comprising at least two pixel electrodes spaced from one another and a layer of an electro-optic medium disposed adjacent the pixel electrodes, the layer of electro-optic medium having a thickness of about 20 to about 25 μm and a volume resistivity of about 1×1010 to about 4×1010 ohm cm.
An electro-optic display comprising at least two pixel electrodes spaced from one another, an adhesive layer adjacent the pixel electrodes, and a layer of an electro-optic medium disposed on the opposed side of the adhesive layer from the pixel electrodes, the adhesive layer having a thickness of about 40 to about 60 μm and a volume resistivity of about 3×109 to about 8×109 ohm cm.
