Abstract

The visible light communication system based on LED display has the functions of display and information transmission at the same time, and has a wide range of potential applications in information broadcasting and stealth advertising. This paper proposes a real-time visible light communication system based on LED display. The system uses the LED display screen as the light source, completes data processing through FPGA, and the detection system uses PIN diodes as the detector to receive the light radiation signal of the display panel. In this paper, the universal asynchronous receiving/transmitting and coding mark reversal scheme is adopted to solve the most critical problem of the display communication system, that is, the timing problem of display data and optical communication data. Experimental results show that the system can receive characters, files, and pictures. Combined with FPGA data processing, when the system transmits data at a rate of 9.6kbps, under the condition of full-screen LED display, the communication distance is 105cm and the bit error rate is 2.7 ×10^-4.
