Abstract
The invention discloses a display based on an OLED (organic light-emitting diode) visible light communication. The display comprises a metallic cathode, an organic light-emitting layer, an anode and an OLED display panel for displaying an image, wherein the organic light-emitting layer is sandwiched between the metallic cathode and the anode; and the OLED display panel can receive light signals. The OLED display also comprises a photoelectric converter and a demodulator circuit which are both coupled on the OLED display panel, wherein the photoelectric converter restores the received visible light into electric signals, and the electric signals are output by the OLED display panel after being demodulated by the demodulator circuit. Through the mode, according to the invention, the visible light communication of the OLED can be realized, and the problems that the light ray distribution of an LED display screen is not uniform and soft enough, the visual angle is restricted, communication can not be carried out comprehensively, the manufacturing technology of the display is complex and the like are overcome.
