Abstract
A display device includes a display panel including, a driving transistor configured to generate driving current, a light emitting element configured to emit light based on the driving current and an initialization transistor configured to apply an initialization voltage to an output electrode of the driving transistor, a sensing driver configured to generate sensing data by receiving the driving current of the pixels through initialization transistors and a driving controller configured to generate accumulated image data by accumulating input image data for frames and to compensate for the input image data based on the accumulated image data and the sensing data.
