Abstract: An electronic device includes a display panel, a first power regulator to supply first power to an anode of light emitting diode (LED) and to supply second power to a cathode of the LED, and a DDI including a second power regulator to supply third power to the anode of the LED and to supply fourth power to the cathode of the LED, and connected with the first power regulator, and a processor. The processor outputs first content based on the first power and the second power, in a first operating mode, outputs second content based on the third power and the fourth power, in a second operating mode, and controls the third power and fourth power respectively to be maintained to be higher than the first power, and the second power when an operating mode is switched.
