摘要： An electro-optic device, and its method of manufacturing, is disclosed comprises a first substrate layer, a conductive film comprising a first adhesive layer and a first electrode layer, an electro-optic material layer, and a second electrode layer. The first electrode layer, which is on contact with the electro-optic material layer, comprises a conductive material, such as conductive particles, a metallic material or a conductive polymer. The first adhesive layer has high storage modulus and does not exhibit plastic flow under the conditions of manufacturing, storage, and operation of the electro-optic device. The conductive film does not conform to the surface roughness of the first surface of the electro-optic material layer. The conductive film may be designed to be thin, flexible and transparent. The resulting electro-optic device exhibit excellent electro-optic performance even where the electro-optic material layer has imperfections in the form of gaps.

摘要： An electro-optic media includes either a plurality of microcapsules in a binder, a polymeric sheet containing sealed microcells, or droplets in a continuous polymeric phase. Each of the microcapsules, microcells, or droplets contain a dispersion that includes a plurality of charged composite particles and a suspending fluid, and the charged particles move through the suspending fluid under the influence of an electric field. The composite particles include one or more types of pigment particles that are at least partially coated with a polymeric material. Each of the binder, polymeric sheet, continuous polymeric phase, the charged composite particles, and the suspending fluid have an index of refraction, and a difference between the index of refraction of the composite particles and at least one of the binder, polymeric sheet, continuous polymeric phase, and solvent is less than or equal to 0.05 at 550 nm.

摘要： A system for simplified driving of electrophoretic media using a positive and a negative voltage source, where the voltage sources have different magnitudes, and a controller that cycles the top electrode between the two voltage sources and ground while coordinating driving at least two drive electrodes opposed to the top electrode. The resulting system can achieve roughly the same color states as compared to supplying each drive electrode with six independent drive levels and ground. Thus, the system simplifies the required electronics with only marginal loss in color gamut. The system is particularly useful for addressing an electrophoretic medium including four sets of different particles, e.g., wherein three of the particles are colored and subtractive and one of the particles is light-scattering.
