摘要:
An edge-addressable electronic display is provided including a row electrode in electric communication with a first termination and a column electrode in electric communication with a second termination. The row and column electrodes intersect at a pixel. Both the first and second terminations are disposed proximate to a first edge of the display, and as a result, the pixel may be addressed along the first edge of the display. The display may further include a removable driver circuitry for addressing the pixel in electric communication with at least one of the first and second terminations.

An electro-optic display includes an electro-optic medium, a pixel electrode for applying an electric field to the medium and a column electrode associated with the pixel electrode. To reduce power consumption, when it is necessary to change the voltage on the column electrode from a first value to a second value to change the optical state of the electro-optic medium, the column electrode voltage is first changed to a third value intermediate the first and second values to permit charge to flow to or from the column electrode, and thereafter the column electrode voltage is changed from the third voltage to the second voltage.

A system for centrally controlling and messaging electrically active displays distributed at a single site or at multiple sites. A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit. This invention also features a display that is both powered and controlled using radio frequencies. It describes a complete system for controlling, addressing, and powering a display. The system includes an antenna or antennae, passive charging circuitry, and active control system, a display, and an energy storage unit. There is also a separate transmitter that provides the remote power for the display. The system is meant to be used anywhere it is useful to provide intermittent updates of information such as in a store, on a highway, or in an airport. A tile-based display allowing a modular system for large area display is created using a printable display material.

A mounted display assembly comprises a flexible substrate that supports both display elements and control circuits. The display assembly generally comprises: an electrical connection formed on the flexible substrate, the electrical connection having first and second contact pads; a display element in electrical communication with the first contact pad; and a control circuit mounted on the flexible substrate and in electrical communication with the second contact pad. In a preferred embodiment, the display element comprises a microencapsulated electrophoretic display medium. In another preferred embodiment, printing processes are employed in manufacturing methods for the display assembly

An application-ready electrophoresis material includes a carrier and a dispersion of microcapsules therein, the microcapsules each containing a plurality of phases therein. At least some of the phases contrast visually and and exhibit differential responsiveness to an electric field, such that application of the field determines the visual appearance of the microcapsules. The material exhibits stability such the visual appearance persists despite removal of the field. In one aspect, the invention provides for enhanced stability of the visual appearance. In another aspect, the reflectivity of at least one of the phases is enhanced. In another aspect, one of the phases is particulate in nature and emits visible radiation.

A flexible solar module is provided sufficient rigidity for use in construction, and comparable rigidity to a glass based solar module, by incorporation of a metal backing to the module, preferably in the laminated module. The rigidity of the construction is enhanced by the inclusion of a corrugation, either in the metal backing, or in a structure that is affixed to the backing. The resulting structure is a modular unit that has connection points and does not need to be connected to other modules to operate. A connection point is provided by an integrated junction box that allows for a simpler installation and the use of standard building techniques for the installation on a roof or wall.

A front plane laminate useful in the manufacture of electro-optic displays comprises, in order, a light-transmissive electrically-conductive layer, a layer of an electro-optic medium in electrical contact with the electrically-conductive layer, an adhesive layer and a release sheet. This front plane laminate can be prepared as a continuous web, cut to size, the release sheet removed and the laminate laminated to a backplane to form a display. Methods for providing conductive vias through the electro-optic medium and for testing the front plane laminate are also described.

An electro-optic display comprises a bistable electro-optic material having a viewing surface and an opposed writing surface; a deformable member disposed adjacent but spaced from the writing surface of the electro-optic material, and bearing elongate electrodes facing the writing surface of the electro-optic material; and a movable member disposed on the opposed side of the deformable member from the electro-optic material and movable parallel to the elongate electrodes, the movable member contacting and deforming the deformable member such that a portion of each elongate electrode contacts or lies closely adjacent the writing surface of the electro-optic material.

An electro-optic display comprises a backplane; a layer of electro-optic material disposed adjacent the backplane; a protective layer; and a sealing layer of a metal or a ceramic extending between the backplane and the protective layer, and thus sealing the layer of electro-optic material from the outside environment.
