Abstract
A driving method of a display device including a power source which supplies a power voltage to a power base line, and pixels connected to power branch lines commonly connected to the power base line, includes calculating a first scale factor based on input grayscales received during a first frame period; calculating first output grayscales by applying the first scale factor to first input grayscales received during a second frame period, where the second frame period is a frame period immediately next to the first frame period; displaying an image by at least a part of the pixels based on the first output grayscales; and providing a first current limiting signal to the power source and calculating a second scale factor smaller than the first scale factor when a current of the power base line exceeds a reference value.
