Abstract
In a display device, each of pixels includes a light emitting element and a pixel circuit which is connected to the light emitting element at a first node and drives the light emitting element in response to a corresponding driving scan signal among driving scan signals during a display period. The pixel circuit is connected to a corresponding readout line among readout lines at a second node. The sensing circuit senses a potential of the first node through the corresponding readout line during a blank period, and each of frames includes the display period and the blank period. At least two driving scan signals among the driving scan signals respectively include a plurality of rewriting periods, each of which is activated during the blank period corresponding thereto, and the rewriting periods of the driving scan signals have different durations from each other.
