Abstract: A display device may include: a display panel configured to be driven in an active time and a blank time within one frame and including pixels each having a driving transistor; a data driver configured to provide a first data voltage based on an image data to the pixels in the active time; and a timing controller configured to compensate for the image data based on a first compensation data for a threshold voltage of the driving transistor and a second compensation data for a mobility of the driving transistor, the timing controller including a data compensator, a non-volatile memory, and volatile memories. The timing controller may be further configured to read a reference first compensation data from the non-volatile memory in the active time and update the first compensation data and the second compensation data to be stored in one of the volatile memories in the blank time.

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.
