Abstract:
Provided is a display device. The display device includes a display to display an image, a processor to control the display to display a predetermined image, a power supplier to generate a direct current (DC) power by receiving an alternating current (AC) power, and supply the generated DC power to each of the display and the processor, and a sensor to output a sensing signal corresponding to whether the AC power is input, and the display stops an image display operation according to the sensing signal.
