Visible light communication (VLC) is a technology that transmits data through blinking light of 300-800 nm. An advantage of VLC is that the network can be simply configured by replacing lighting modules installed indoors or outdoors. Existing VLC use monochromatic light-emitting diode (LED) to communicate with a single wavelength, limiting transmission speeds. It was composed of multiple channels to widen the communication bandwidth, but interference problems occurred because a single wavelength of light was used. To reduce interference, there is a study to configure multi-channel with a laser with good straightness, but this requires a complicated structure and high cost. In this paper, we have developed a wavelength-matched all-organic VLC system using an organic LED as an emitting unit and an organic photodiode as a receiving unit with multi-channels. Therefore, it can stably transmit more data without interference is expected, even when multiple channels are used.
