Abstract: An electronic device (20) includes a liquid crystal display (10) capable of being viewed from opposing sides. The display includes a liquid crystal display glass layer (2) selectively coated with a polarizer layer (4) and a transflective layer (6) on portions of a first viewable side (3) and selectively coated with another polarizer layer (7) and another transflective layer (5) on an opposing second viewable side (8) of the liquid crystal display glass layer such that the respective polarizer layers and transflective layers would oppose each other on the opposing sides of the liquid crystal display glass layer. Additionally, the device includes a liquid crystal display driver (18) capable of generating images on opposing sides of the liquid crystal display.

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.
