Abstract: A color electrophoretic display with distinct switching areas formed by a segmented top plane electrode opposite driving pixel electrodes. The distinct areas are programmed to switch at different times, thereby reducing the “flashiness” seen by a viewer during an image update. In one embodiment, the color electrophoretic medium of the display includes a reflective white particle and three other sets of particles, each comprising a different color.

Abstract: Improved methods for driving an active matrix of pixel electrodes controlled with thin film transistors when the voltage on a top electrode is being altered between driving frames. The methods described increase performance by providing smaller swings in the overall voltage between the top electrode and pixel electrode while reducing stress on the thin film transistor.

Abstract: Methods of making a top-plane connection in an electro-optic device and devices including such connections. A through hole is created through a rear substrate to provide a connection between a conductor coupled to the rear substrate and a light-transmissive conductive layer coupled to a top transparent substrate. The hole is subsequently filled with a top-plane connection material that provides an electrical connection between the conductor and the light-transmissive conductive layer, but does not provide an electrical connection between a separate rear conductive layer and the light-transmissive conductor.

Abstract: An electrical connection between the backplane and the light-transmissive front electrode of an electrowetting device is provided by forming an aperture through the top front electrode coupled and a substrate coupled thereto and subsequently introducing a flowable, electrically-conductive material into the aperture. The flowable, electrically-conductive material provides an electrical contact between the light-transmissive electrically-conductive layer and the backplane.

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: A display apparatus including: a plurality of display tiles; a controller configured to control the display tiles; a mounting structure for mounting the plurality of display tiles, the mounting structure including a conductive interconnect layer having a plurality of traces configured to connected the plurality of display tiles to the controller, and a connector connecting at least one display tile to the mounting structure. The at least one display tile is sufficiently flexible to have a curvature, wherein the curvature produces a space between the at least one display tile and the mounting structure to house the controller.

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: Polymer formulations including urethane acrylates, adhesion promoters, and conductive monomers. By selecting suitable conductive monomers, it is possible to achieve formulations having a volume resistivity from 106 to 1010 Ohm·cm after being conditioned for one week at 25° C. and 50% relative humidity. Such formulations are suitable for incorporation into electro-optic materials, such as electro-optic displays or variable transmission films, e.g., for architectural applications. In other embodiments, the formulations additionally include metal oxide nanoparticles to alter the refractive index and/or conductivity.
