Abstract: A display device includes a display panel, a scan driver that provides a scan signal to the display panel, a data driver that provides a data signal to the display panel, a driving controller that controls the scan driver and the data driver, a temperature sensor that senses local temperatures of local regions of the display panel using a temperature sensor and generates temperature sensing information, a current sensor that senses driving currents of the local regions and generates current sensing information, and a sensing controller that selects sensing target regions based on respective degradation degrees of the local regions, determines sensing priorities between the sensing target regions, and controls the sensing target regions to be sequentially sensed only during a sensing execution time according to the sensing priorities between the sensing target regions.
