1. A power circuit comprising:
a direct current to direct current converter configured to output a first voltage;
a digital-to-analog converter configured to convert input data to an analog voltage and output a second voltage; and
a voltage regulating circuit configured to receive the first voltage and the second voltage as inputs and output a voltage in which the second voltage is added to the first voltage, and reduce a slope of the voltage,
wherein the input data to the digital-to-analog converter is updated during one horizontal period of a display device, and
wherein the voltage regulating circuit is further configured to commonly supply the voltage to pixels of the display device.
