1. A display device comprising:
a power supply circuit configured to supply a DC voltage or a burst wave voltage to the display device as power;
a microphone configured to sense noise of the display device; and
a controller configured to obtain a magnitude of the noise and adjust a slope of the burst wave voltage for the power supply circuit based on the magnitude of the noise,
wherein the controller is configured to adjust the slope of the burst wave voltage based on a rate of change of the burst wave voltage from a time when the display device switches to a standby state.
