Abstract
A display device includes: a pixel unit including a pixel connected to a data line; a data driver which supplies a sensing reference voltage to the data line during a sensing period, and supplies a data signal to the data line during a display period; and a sensing unit which receives a sensing current corresponding to the sensing reference voltage during the sensing period, and generates correction data based on the supplied sensing current. The sensing unit includes a current integrator which outputs a sensing voltage based on the sensing current input thereto through a first input terminal and based on the sensing reference voltage input thereto through a second input terminal.
