Abstract: Provided are a charging/discharging apparatus, an operation method of the charging/discharging apparatus, and a display apparatus including the charging/discharging apparatus. The charging/discharging apparatus includes a charging unit comprising circuitry configured to charge a battery pack, and a direct current (DC)-DC converter configured to convert a battery voltage of the battery pack into a voltage for operating the display apparatus, wherein, in a first mode based on an alternating current (AC) power source being applied to the display apparatus, the charging/discharging apparatus charges the battery pack with a battery voltage less than a secondary voltage generated by the display apparatus from the AC power source through the charging unit, and in a second mode based on the AC power source not being applied to the display apparatus, the charging/discharging apparatus delivers the battery voltage of the battery pack to the display apparatus.

Abstract: A display device according to an embodiment includes a display, a first power module that outputs a first power, and a second power module that outputs a second power. The first power and the second power are supplied to the display. The first power module is configured to cut off the first power when an amount of input current exceeds an overload criterion, to identify whether the second power module is abnormal based on the second power, and to change the overload criterion from a first threshold current amount to a second threshold current amount that exceeds the first threshold current amount, in an abnormal state of the second power module.
