摘要： A fiber capable of switching optical states is provided. The fiber includes a laminate having a first electrode layer, a second electrode layer, and an electro-optic material between the first and second electrode layers, at least one of the first and second electrode layers being light-transmissive and a sheath surrounding the laminate. The fiber may have a ribbon-like structure, i.e. a width that is substantially greater than its thickness. The electro-optic medium may be an encapsulated electrophoretic medium.

摘要： A temperature regulation system includes a laminate material that has a first light transmissive electrode layer, a rear electrode layer, and a bistable electrophoretic medium disposed between the first and second electrode layer. The electrophoretic medium includes two types of particles that have different charges and color. The amount of incident radiation (visible light, infrared, etc.) that is absorbed by the laminate can be modified by providing a voltage between the electrode layers.

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： An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

摘要： Improvements in the production of electro-optic displays include: (a) use of a masking film to keep a selected area of a backplane (such as a front electrode contact) free from electro-optic material; (b) spray coating of electrophoretic capsules on to a substrate under controlled conditions; (c) forming a monolayer of capsules on a substrate by prior deposition of a water-swellable polymer; and (d) overcoating a layer of electro-optic material with a solvent-free polymerizable liquid material, contacting this layer with a light-transmissive electrode layer, and polymerizing the liquid material to adhere the electrode layer to the electro-optic material.

摘要： A capsule comprising a capsule wall and an electrophoretic fluid encapsulated by the capsule wall. The capsule wall comprises a cross-linked nonionic, water-soluble or water-dispersible polymer. The electrophoretic fluid comprises a suspending fluid, first pigment particles, second pigment particles, and third pigment particles. In some embodiments, the electrophoretic fluid includes a fourth electrophoretic particle. The first, second, and third particles are electrically charged, suspended in the suspending fluid, and capable of moving through the suspending fluid upon application of an electric field to the capsule.

摘要： 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.
