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.

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.

Abstract: A method of forming a color-changing fiber that can be incorporated into fabrics and other woven materials. The color changing fibers include an annular wall and a conductive wire axially extending through the annular wall, a core strand surrounded by the annular wall and extending axially through a central portion of the fiber, and an encapsulated electro-optic medium disposed on a surface of the core strand.

Abstract: An electrophoretic medium includes a fluid, a first, light scattering particle (typically white) and second, third and fourth particles having three subtractive primary colors (typically magenta, cyan and yellow); at least two of these colored particles being non-light scattering. The first and second particles bear polymer coatings such that the electric field required to separate an aggregate formed by the third and the fourth particles is greater than that required to separate an aggregate formed from any other two types of particles. Methods for driving the medium to produce white, black, magenta, cyan, yellow, red, green and blue colors are also described.

Abstract: An electro-optic display comprising, in order: a light-transmissive layer of conductive material; a layer of bistable electro-optic medium; a layer of light-shielding material; a plurality of pixel electrodes; a layer of photoconductive material; and one or more light emitters. In one exemplary embodiment, the layer of photoconductive material is adapted to bridge a gap between an address line and at least one of the pixel electrodes when the photoconductive material is in a low impedance state. In another, non-exclusive embodiment, the electro-optic display further comprises a second electrode layer between the layer of photoconductive material and the one or more light emitters and a driver adapted to apply voltage between the light-transmissive layer of conductive material and the second electrode layer.

Abstract: A method for degassing a microfluidic droplet by combining electrowetting and heating to induce formation of gaseous bubbles in the droplet. In an embodiment the methods are carried out on an active matrix of electrowetting electrodes including a hydrophobic coating. A carrier fluid is flowed against the droplet motion propelled by electrowetting to facilitate rapid removal of the gasses departing the droplet.

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.
