Electronic device including organic light emitting display device

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;
• 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.

At least one non-transitory computer readable storage medium storing one or more programs including instructions, which when executed by a processor of an electronic device, perform a method of:

• outputting, by a first regulator of a display power management integrated circuit (IC) (PMIC) included in the electronic device, a first voltage resulting from conversion of a size of an input voltage inputted to the PMIC;
• outputting, by a second regulator of the PMIC, a second voltage resulting from inversion of a phase of the input voltage and conversion of the size;
• receiving, by a display driver IC (DDI) of a display included in the electronic device, at least one of the first voltage or the second voltage;
• outputting, to a display panel, a third voltage in which the phase of the input voltage is maintained based on the first voltage;
• and
• outputting, to the display panel, a fourth voltage in which the phase of the input voltage is inverted based on the second voltage.
