A mobile terminal is a communication device that communicates using visible light, and includes: a plurality of light emitters, each of which is disposed along the front surface of the mobile terminal and transmits a visible light signal; and a plurality of light receivers, each of which is disposed along the front surface and receives a visible light signal. The plurality of light emitters are disposed on the left side of all of the plurality of light receivers, and the plurality of first light receivers are disposed on the right side of all of the plurality of light emitters.

A flyback power converter circuit includes a transformer, a blocking switch, a primary side switch, a primary side controller circuit and a secondary side controller circuit. The transformer is coupled between an input voltage and an internal output voltage in an isolated manner. The blocking switch controls the electric connection between the internal output voltage and an external output voltage. In a standby mode, the internal output voltage is regulated to a standby voltage, and the blocking switch is controlled to be OFF; in an operation mode, the internal output voltage is regulated to an operating voltage, and the blocking switch is controlled to be ON, such that the external output voltage has the operating voltage. The standby voltage is smaller than the operating voltage, so that the power consumption of the flyback power converter circuit is reduced in the standby mode.
