ABSTRACT:
An electronic display license plate and message center for use on automobiles and other vehicles. The electronic display license plate is a replacement for the standard metal license plate, and may be constructed as a part of the car, such as an integral part of the taillight assembly, or may be constructed as a bolt-on replacement module for existing license plates. The display may be constructed from an array of light-emitting diodes, or a liquid crystal display, or from an electroluminescent panel. A configuration cartridge, typically containing a read only memory (ROM) circuit, contains license plate information such as state, county, license number, and expiration date, configures the display for the particular vehicle. The electronic display license plate may also contain circuitry to detect the expiration of the license and appropriately indicate that expiration by flashing or inverting the display, or causing it to go blank.
