1. A display device comprising:
a power source supply configured to receive power from an external power source; and
a processor configured to detect a voltage of the power supplied from the power source supply, detect a voltage drop of the supplied power on the basis of the detected voltage of the power, and reset power source of a memory controller and a main power source within a predetermined time when the voltage drop is detected,
wherein the processor is configured to:
determine whether the detected voltage of the power has a voltage drop above a predetermined drop range; and
reset the power source of the memory controller within the predetermined time when the voltage drop above the predetermined voltage drop range occurs in the detected voltage of the power.
