Abstract
A display device includes: pixels; and a power converter for receiving a first voltage, converting the first voltage to a second voltage, and providing an output terminal with the second voltage to control the pixels. The power converter includes: a first variable load connected to the output terminal of the power converter; a first comparator for providing a comparison result by comparing a difference between a first feedback voltage of the first voltage and a second feedback voltage of the second voltage; and a gap controller for controlling a magnitude of the first variable load to maintain the difference between the first voltage and the second voltage to be greater than or equal to a gap, based on the comparison result received from the first comparator.
