  • Publication number: 20160284278
    Abstract: A multi-color display device has front and rear electrodes on opposed sides of an electrophoretic medium. The device has a voltage controller configured to apply a first and a smaller second potential difference, of either polarity, between the electrodes. The electrophoretic medium has first and second species of particles of differing colors and charge polarities. The first and second particles move independently of one another in response to the first potential difference, but upon application of the second potential difference form charged aggregates, moving as a unit, having an aggregate color different from the first and second colors.

  • Publication number: 20160232835
    Abstract: A first display comprises a layer of electro-optic material with first and second electrodes on opposed sides thereof, at least one electrode. One or both electrodes having at least two spaced contacts, and voltage control means are arranged to vary the potential difference between the two spaced contacts attached to the same electrode. A second display comprises 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 the two surfaces of the layer of electro-optic material, and have edges which overlap with 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.

  • Patent number: 9361836
    Abstract: A multi-color display device has front and rear electrodes on opposed sides of an electrophoretic medium. One of the front and rear electrodes occupies only a minor proportion of a pixel. The device has a voltage control capable of applying a first and a smaller second potential difference of either polarity between the electrodes. The electrophoretic medium has first and second species of particles of differing colors and charge polarities. The first and second particles move independently of one another in response to the first potential difference, but upon application of the second potential difference form charged aggregates, moving as a unit, having an aggregate color different from the first and second colors.

  • Patent number: 9195111
    Abstract: An electro-optic medium comprises at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli. The medium allows for development of differing colors in differing areas of the medium, thus allowing formation of intrinsic color within differing areas of a single layer of the same electro-optic medium. In an electrophoretic medium, the colors may be developed within the electrophoretic particles or within the fluid in which the particles are dispersed.
