Abstract
A display device includes pixels connected to scan lines, sensing lines, readout lines, and data lines; a scan driver including stages to supply a scan signal and a sensing signal to the scan lines and the sensing lines; a data driver which supplies a data signal to the data lines; a timing controller which divides one frame into an active period including a scan period in which the data signal is supplied to the data lines and a display period in which the pixels emit light in response to the data signal, and a blank period including a sensing period in which electrical characteristics of the pixels are detected and a reset period in which the stages are reset; and a compensator which generates a compensation value for compensating for deterioration of the pixels based on sensing values provided from the readout lines during the sensing period.
