Abstract

A display for selectively operating, for example, light-emitting diodes, comprising DC power supplies (PW1 to PW3) capable of outputting voltages of mutually different voltage values, a pair of power supply cables (13) for supplying a selected one of the voltages outputted from the DC power supplies (PW1 to PW3), voltage supply control means (11, 12) for supplying one of the voltages to the power supply cables (13), a voltage identifying section (15) connected to the power supply cables and adapted for identifying the voltage supplied through the power supply cables (13) on the basis of the voltage value, an LED section (17) including light-emitting diodes driven by drive voltages of mutually different voltage values supplied through the power supply cables (13), and an LED drive section (16) for supplying the voltage identified by the voltage identifying section (15) to the corresponding light-emitting diode in the LED section (17).
