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.
