Abstract: A power supply device and a display device including the same disclosed. In one aspect, the power supply device includes a DC-DC converter including a power supply having an input voltage and configured to generate a power voltage and a power current based at least in part on the input voltage and a feedback voltage and supply the power voltage to an output line. A detector is configured to detect the power voltage and the power current, a feedback circuit configured to generate the feedback voltage based at least in part on the power voltage and the power current and supply the feedback voltage to the DC-DC converter. A memory is configured to store a power error voltage signal corresponding to a power error voltage including the difference between the power voltage and a reference power voltage.
