Abstract
A display device includes: a plurality of pixels, each being coupled to a corresponding data line among a plurality of data lines and a corresponding scan line among a plurality of scan lines; a scan driver to supply a scan signal to the scan lines; a sensor coupled to the pixels and the data lines and configured to detect a sensing current according to a test signal input to the data lines; and a controller configured to detect a pixel current of a pixel corresponding to a scan line to which the scan signal is supplied, by using a first sensing current corresponding to a first pixel and a second sensing current corresponding to a second pixel, when the scan signal is selectively supplied to a first scan line coupled to the first pixel and a second scan line coupled to the second pixel.
