  • Publication number: 20190272791
    Abstract: Video displays using relatively low frame rates of about 10 to about 20 frames per second, but having acceptable video quality are described. The displays may use bistable media, and may be driven such that the medium, when driven, changes its optical properties continuously during the driving of each frame. The displays may use an electro-optic medium such that the frame period is from about 50 to about 200 per cent of the switching time of the electro-optic medium at the driving voltage used.

  • 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: 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.

  • Publication number: 20180239212
    Abstract: 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.
