PURPOSE: A visible light communication device and a method thereof for displaying communication quality by using an RGB color combination in order to intuitively confirm the reception quality of data transmitted through a visible light signal are provided to variously express error in various colors through RGB color combination. CONSTITUTION: A signal generator(160) determines the received quality of a visible light receiving signal by using the property of the signal of a target wavelength. The signal generator generates the visible signal by using light sources according to the reception quality. A light signal transmitter(125) transmits a signal of the target wavelength with the visible signal. The light signal transmitter changes the emitted light color of the visible light transmission signal. |
