Abstract: Disclosed is a display device including: pixels each including a driving transistor that includes a first electrode receiving a high-potential driving voltage, a second electrode connected to an anode of a light emitting element, and a gate electrode receiving a data voltage; a source driving integrated circuit (IC) configured to receive a sensing information output from each of the pixels and corresponding to a threshold voltage of the driving transistor; and a timing controller configured to calculate the threshold voltage of the driving transistor in each pixel based on the sensing information, the timing controller including: a defective pixel detector configured to detect a defective pixel by receiving the sensing voltages of the pixels from the source driving IC, and a sensing range controller configured to adjust a first sensing range preset for the ADC upon presence of the defective pixel detected by the defective pixel detector.
