Abstract: A power circuit can include 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. Also, the input data to the digital-to-analog converter is updated during one horizontal period of a display device, and the voltage regulating circuit is further configured to commonly supply the voltage to pixels of the display device.
