Abstract:
An electronically controllable/programmable sign comprises a multi-layer display device, a display driver (94) for applying at least one field across the image layer in accordance with a display signal, and a controller (96) for providing the display signal to the display driver. The multilayer display device includes at least one image layer (12, 62, 74). The image layer has one or more regions (12, 12A, 12B) of reflective media whose reflectivity changes in response to an applied fields. An electronically conductive layer (10) is positioned on one side of the image layer; and a counterelectrode layer (14) is positioned on the other side of the image layer.
Abstract:
A method of creating or changing an image on an electric paper display includes selectively applying electric fields to various regions of bichromal media (1). The methods may apply the fields in a manner such that the vector sum of all fields applied equals zero (3-A - 3D), and/or the methods may wipe clean the bichromal media so that a single-color screen is displayed before a new image is applied (6D).
Abstract:
A system and method for remotely updating messages displayed on a plurality of low power consuming electronic display devices. The system comprises a server computer remotely located from a bistable display device which is in wireless communication with a computer network connected to said server computer. The server computer manages the updating and display of messages on the display device by providing new content and scheduling the display of the content. Except when changing the message display or communicating with the server computer, the display device operates in a low power mode

Abstract:
A system and method for remotely updating messages displayed on a plurality of low power consuming electronic display devices. The system comprises a server computer (101) remotely located from a bistable display device (105) which is in wireless communication with a computer network (206) connected to the server computer (101) . The server computer (101) manages the updating and display of messages on the display device (105) by providing new content and scheduling the display of the content. The display device (105) operates in low power mode (424) except when changing the message display or communicating with the server computer (101).
