Abstract
Exemplary embodiments of the present invention disclose a display device, and a method of driving the same. The display device includes a display unit including pixels included in one or more deterioration region groups and pixels included in one or more reference groups corresponding to the deterioration region groups, a sensing unit configured to sense a current flowing through an organic light emitting diode of each of the deterioration region groups and each of the reference groups and provide current information about the deterioration region group and current information about the reference group. Exemplary embodiments of the present invention also provide a compensation circuit configured to convert first data supplied from the outside into second data by using compensation data corresponding to a compensation prediction curve and output the second data, and compare the current information about the deterioration region group and the current information about the reference group and correct the compensation prediction curve for the deterioration region group; and a data driver configured to supply the second data to the display unit through data lines as data signals.
