Abstract: A hybrid display including an emissive display adjacent a variable transmission display. The hybrid display device typically includes a controller. The emissive display provides an image that is viewable from a viewing location, and the variable transmission medium is positioned relative to the emissive display to partially alter the image at the viewing location. The controller generates a desired altered image at the viewing location by controlling the electrophoretic image display or the variable transmission medium. The display device can include an ambient light sensor. The hybrid display can be incorporated into a combination display by combining the hybrid display with one or more additional electrophoretic displays.

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: A light-transmissive substrate having an inner surface, an outer surface opposite the inner surface, and a plurality of through holes. When coupled with a light-transmissive conductive material; such as indium tin oxide (ITO), the substrate provides electrical connections between a light-transmissive electrically-conductive layer, which may be used as a top electrode in an electro-optic display, and contact spots on the outer surface of the light-transmissive substrate. Accordingly, the light-transmissive substrate allows for simpler electrical connections for electro-optic displays, especially for large format devices that may need to be cut or assembled in the field. Additionally, the redundancy of having tens to hundreds of electrical contacts minimizes the chance that a device will be rendered inoperable due to a broken electrical connection.

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: 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: The present invention provides for a method of rendering an image on a reflective display wherein each pixel is capable of rendering a limited number of colors, each of which is rendered by predetermined set of waveforms stored in a waveform lookup table. Furthermore, the present invention provides for a method for rendering an image using such colors, having been chosen for optimal color rendition. This invention further provides for rendering a color image formed from a plurality of pixels on a reflective display wherein each pixel has a color selected from the group consisting of at least: red, green, blue, cyan, magenta, yellow, black and white.
