1. A composite display apparatus comprising:
multiple display devices each including a power supply having predetermined supply power; and
a power supply connection unit that connects the power supplies of the respective display devices to each other in parallel, wherein,
in a case where at least one display device among the multiple display devices requires electric power exceeding the predetermined supply power of the power supply of the display device, electric power is supplied to the display device from the power supply of the other display device or devices,
wherein
each of the display devices includes a power supply controlling circuit that controls supply of electric power from the power supply of the own display device, and
a first power supply controlling circuit that is the power supply controlling circuit in a predetermined one of the multiple display devices also controls the power supply controlling circuit of the other display device or devices in such a manner that supply of electric power of the power supplies of the respective display devices is balanced,
wherein
the power supply controlling circuit of each of the multiple display devices acquires a control signal for controlling whether or not the power supply controlling circuit is to operate as the first power supply controlling circuit that also controls the power supply controlling circuit of the other display device or devices, and
a predetermined one of the power supply controlling circuits that has acquired the control signal indicating that the power supply controlling circuit is to operate as the first power supply controlling circuit operates as the first power supply controlling circuit.
