Abstract: A display device can include a display panel having a plurality of sub-pixels, a data driver configured to apply a data signal to the plurality of sub-pixels, a gate driver configured to apply a gate signal to the plurality of sub-pixels, a timing controller configured to output control signals to the data driver and the gate driver, and a power controller configured to detect a defect associated with the display panel, and generate and output a defect signal corresponding on a type of the detected defect. The timing controller stores defect-related information associated with the defect signal.
