Abstract
An electronic device includes a display panel, a first power regulator to supply first power to an anode of light emitting diode and second power to a cathode of the light emitting diode, and a DDI including a second power regulator to supply third power to the anode of the light emitting diode and fourth power to the cathode of the light emitting diode, 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 to be higher than the first power, and the fourth power to be higher than the second power, when an operating mode is switched.
