Abstract

An electronic display system comprising a communication system including modulator means (2) arranged to modulate electromagnetic radiation inadvertently radiated from an electronically operated display (1) with which said modulator means (2) is operatively associated, (e.g. radiation emanating from an electronic screen), for the purpose of transmitting information to portable receivers (3) (e.g. appropriately adapted mobile phones, MP3 players, Personal Digital Assistants, portable radios, music players or the like), whereby the portable receivers (3) are enabled to receive the information.
