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
