ABSTRACT:
A system (10) and method of communicating data utilizes an electroluminescent panel (12). The frequency of the drive signal for the electroluminescent panel (12) is modulated in accordance with data to be transmitted. The electroluminescent panel (12) is responsive to the drive signal to emit light at frequencies representing the data. A second electroluminescent panel (12') may be positioned adjacent to the first electroluminescent panel (12) to receive the data encoded light emitted therefrom. The second electroluminescent panel (12') generates a signal representing the received light, the signal being demodulated to recover the data encoded therein.
