1. An electronic device comprising:
an organic light emitting display device comprising:
a display panel comprising a plurality of gate lines, a plurality of data lines, and a plurality of pixels; and
a display driver integrated circuit (IC) (DDI) configured to drive the display panel; and
a display power management IC (PMIC) configured to generate a voltage necessary for driving the display driver IC,
wherein the display PMIC comprises:
a first regulator configured to output a first voltage resulting from conversion of a size of an input voltage inputted to the display PMIC, and
a second regulator configured to output a second voltage resulting from inversion of a phase of the input voltage and conversion of the size, and
wherein the display driver IC is configured to:
receive at least one of the first voltage or the second voltage,
output, to the display panel, a third voltage in which the phase of the input voltage is maintained based on the first voltage, and
output, to the display panel, a fourth voltage in which the phase of the input voltage is inverted based on the second voltage.
