Electronic sign
First Claim
1. An electronic display system suitable for displaying information, said system comprising:
- a first electrode;
a second electrode;
a bi-stable display medium between the first electrode and the second electrode;
a physical set of related font regions associated with the first and second electrodes for providing a selected type face at a selected size, wherein each font region member of the physical set is addressable via at least one of the first or second electrodes to activate the bi-stable display medium to display a glyph defined by the addressable related font region members in the physical set.

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.
