| Zusammenfassung: | A power supply device includes: a display power supply circuit that receives a voltage and outputs a power supply at a predetermined voltage to a display; and a voltage switching circuit configured to, when a voltage value of a battery is equal to or higher than a predetermined value, output a first voltage to the display power supply circuit, the first voltage being based on the voltage that the battery outputs, and when a voltage value of the battery is less than the predetermined value, outputs a second voltage higher than the first voltage to the display power supply circuit, the second voltage being based on the voltage that the battery outputs. |
