Original Abstract Submitted
A display device includes pixels connected to scan lines, control lines, data lines, and sensing lines; a scan driver configured to supply a scan signal to the scan lines and supply a control signal to the control lines; a data driver configured to supply one of an image data signal and a sensing data signal to the data lines; a sensing circuit configured to sense the characteristics based on a sensing current supplied through the sensing lines during the sensing period; and a power supply configured to supply a voltage of first power to the pixels. The sensing period includes a first sensing period during which a first sensing current is extracted based on a first sensing data signal corresponding to a first grayscale, and a second sensing period during which a second sensing current is extracted based on a second sensing data signal corresponding to a second grayscale, and the voltage of the first power supplied during the first sensing period is different from the voltage of the first power supplied during the second sensing period.
