Classification: CPC G | IPC G

Claim 10:
11. A display device comprising:
a first power module configured to output a first power;
a second power module configured to output a second power;
a display configured to be driven while the first power and the second power are supplied to the display; and
a processor, wherein the processor is configured to:
sense an abnormal state of the second power module, based on the second power; and
reduce a luminance of the display to less than a threshold luminance, in the abnormal state of the second power module, and

wherein the first power module is configured to:
in a normal state of the second power module,
set an overload criterion, and
cut off the first power when an output current amount exceeds the overload criterion set; and

in the abnormal state of the second power module,
change the overload criterion from a first threshold current amount to a second threshold current amount that exceeds the first threshold current amount, the second threshold current amount corresponding to a state in which the luminance of the display is the threshold luminance, and
cut off the first power when the output current amount exceeds the overload criterion based on the change to the second threshold current amount.
