Abstract: An image is formed on an architectural surface by applying to the surface, in order: a rear electrode layer; a light-transmissive front electrode layer; a photoconductive layer disposed between the front and rear electrode layers; and an electro-optic layer disposed between the front and rear electrode layers. A potential difference is applied between the front and rear electrode layers and the front electrode layer is imagewise exposed to radiation which causes a change in the conductivity of the photoconductive layer, thereby causing an imagewise change in the optical state of the electro-optic layer. Films for application to architectural surfaces are also provided.

Abstract: A method for making electrophoretic displays layers including various thin films that are deposited directly onto a layer of microcapsules of electrophoretic media. In an embodiment, a thin film of a light-transmissive conductive material is deposited to create a clear front electrode for an electrophoretic display. In some embodiments, both a dielectric layer and a thin film of a light-transmissive conductive material will be deposited onto the microcapsules.

Abstract: Systems and methods are disclosed for pressure-sensitive, electrophoretic displays, which may optionally include haptic feedback. A display may comprise a first conductive layer having a pressure-sensitive conductivity and an electrophoretic layer positioned adjacent to the first conductive layer, wherein the electrophoretic layer is in electrical communication with the first conductive layer and is configured to locally change state based on a pressure applied to the first conductive layer. Local and global writing and erasing of the display can also be achieved.

Abstract: A hybrid reflective-emissive display including an electrophoretic medium. The electrophoretic medium includes two types of oppositely-charged, and differently-colored, particles in a fluid. The electrophoretic medium is disposed between a front light-transmissive electrode and a rear electrode including a plurality of apertures, such as a hexagonal grid. The electrophoretic layer is optionally illuminated by a light source disposed on the opposite side of the rear electrode from the electrophoretic medium. A viewer can see either the first or second type of particle at the viewing surface, or one of the particles can be illuminated by the light source, thus emitting light the color of one of the particles.

Abstract: A variable opacity material is provided that may be in the form of a mixture, such as an emulsion that contains a discontinuous aqueous polymeric solution having an LCST of 0 to 100° C. and a continuous phase containing a hydrophobic polymer, such as a polysiloxane. One or more salts, such as lithium bromide and sodium chloride, may be added to the aqueous solution to lower the LCST of the aqueous solution and to raise the refractive index of the aqueous polymeric solution to substantially match the refractive index of the hydrophobic polymer. The variable opacity materials may be applied in the form of a film to various substrates, such as glass.

Abstract: The subject matter presented herein relates to a method for producing a backplane for electro-optic displays. The method may include providing a substrate coated with a first conductive material on a first side and a second conductive material on a second side, the second side being positioned opposite from the first side, patterning the first conductive material by cutting through the first conductive material, wherein the patterning of the first conductive material creates electrical isolated conductive segments to be controlled by a driver circuit and creating a plurality of vias on the substrate, the plurality of vias extending through the substrate and providing electrical conductivity between the first and second sides. The method may further include creating a plurality of conductive traces on the second side of the substrate by patterning the second conductive material by locally align the vias to the driver circuit.
