Abstract
The present invention is an electronic display system (100) that includes one or more electronic display apparatuses (110) wired or wirelessly connected to a network central processor (112). Each electronic display apparatus (110) further includes a receiver unit (114), a processor unit (116), a content database (118), driver circuitry (120), a printhead (122), and an electronic display (124). The electronic display (124) is typically a passive monochrome or full color display that is electrically writable and erasable and retains its image until erased and re-written by another transmission. In an alternative embodiment, electronic display (124) is a passive full-color display that is likewise electrically writable and erasable and retains its image until erased and re-written by another transmission.
