  • Patent number: 10388233
    Abstract: Devices and techniques for electronically erasing an externally addressed electrophoretic drawing device are described. An electronically-erasable drawing device comprises an electro-optic display medium and interdigitated electrodes disposed adjacent one surface of the medium and configured to drive the medium to an intermediate (gray) optical state. A mobile electronic drawing implement may include electrodes configured to apply a fringing electric field to an electro-optic display medium from one side of the medium, the fringing electric field being arranged to drive a portion of the display medium adjacent the implement to an intermediate optical state, the electrodes being movable relative to the medium.

  • Patent number: 10372008
    Abstract: A wavelength selective reflection display (10) comprises a wavelength selective reflection medium (20) and a backing member (30) having a first, non-reflective optical state, and a second, reflective optical state. Both the wavelength selective reflection medium (20) and the backing member (30) are divided into pixels (40, 50, 60), and the backing member (30) is switchable between its first and second optical states on a pixel-by-pixel basis. The pixels of the backing member (30) are substantially aligned with those of the wavelength selective reflection medium (20).

  • Publication number: 20190187533
    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.

  • Publication number: 20190185742
    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.

  • Patent number: 10324354
    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: 10317767
    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.

  • Publication number: 20190164505
    Abstract: An electrophoretic display comprising a fluid including a first species of particles and a charge control agent disposed between first and second electrodes. When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

  • Publication number: 20190121215
    Abstract: A first display includes a layer of electro-optic material with first and second electrodes on opposed sides thereof. One or both electrodes have at least two spaced contacts. Voltage control means are arranged to vary the potential difference between the two spaced contacts attached to the same electrode. A second display includes a layer of electro-optic material with a sequence of at least three electrodes adjacent thereto. Voltage control means vary the potential difference between the first and last electrodes of the sequence. The electrodes of the sequence alternate between two surfaces of the layer of electro-optic material, and have edges that overlap or lie adjacent the preceding and following electrodes of the sequence. The electrodes, other than the first and last, are electrically isolated such that the potential thereof is controlled by passage of current through the layer of electro-optic material. Methods for driving these displays are also provided.
