Abstract:

An electronic sign employs a bi-stable, non-volatile display material activatable by electrodes to convey information. A sensor detects when the electronic sign is inserted in or in the vicinity of an insertion area, and controls the operation of the sign based on the detected location. A backplane in the electronic sign includes different patterns of addressable elements to provide a display that pixel, font region, or icon addressable or have a combination of one or more of the pixel, font region, or icon addressability. A remote device communicates with the electronic sign, and multiple electronic signs may communicate with each other via a communication protocol, such as mesh networking.
