  • Publication number: 20150261057
    Abstract: The present invention provides for an electro-optic display having a backplane assembly with at least two electrode layers, a first electrode layer of a first dimension electrically connected to and driving a second electrode layer of a second dimension that is larger than the first dimension. The second electrode layer overlies the first electrode layer, such that the entire viewing area of an electro-optic display may be optically-active. The backplane assembly may have at least one interposer layer disposed between the two electrode layers to electrically connect the first and second electrode layers.

  • Publication number: 20150226986
    Abstract: A first electro-optic display comprises first and second substrates, and an adhesive layer and a layer of electro-optic material disposed between the first and second substrates, the adhesive layer comprising a mixture of a polymeric adhesive material and a hydroxyl containing polymer having a number average molecular weight not greater than about 5000. A second electro-optic display is similar to the first but has an adhesive layer comprising a thermally-activated cross-linking agent to reduce void growth when the display is subjected to temperature changes. A third electro-optic display, intended for writing with a stylus or similar instrument, is produced by forming a layer of an electro-optic material on an electrode; depositing a substantially solvent-free polymerizable liquid material over the electro-optic material; and polymerizing the polymerizable liquid material.

  • Patent number: 9075280
    Abstract: An electro-optic display comprises, in order, a backplane comprising a plurality of pixel electrodes; a layer of a solid electro-optic medium; a main adhesive layer; and at least one of a light-transmissive protective layer and a light-transmissive electrically-conductive layer. The electro-optic layer may be in direct contact with the backplane or separated therefrom by a thin auxiliary layer of adhesive. The main adhesive layer may be colored to provide a color filter array. An inverted front plane laminate useful in forming such a display comprises the same layers except that the backplane is replaced by a release sheet. The display combines good low temperature performance and good resolution at higher temperatures.

  • Publication number: 20140226198
    Abstract: An electro-optic medium comprises at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli. The medium allows for development of differing colors in differing areas of the medium, thus allowing formation of intrinsic color within differing areas of a single layer of the same electro-optic medium. In an electrophoretic medium, the colors may be developed within the electrophoretic particles or within the fluid in which the particles are dispersed.
