Abstract: A display device includes an image controller that analyzes first image data to determine whether a same image is displayed for no less than a predetermined threshold time. The image controller sets a low grayscale region having grayscale values of no more than a predetermined threshold low grayscale value when the same image is displayed for no less than a threshold time. The image controller then receives second image data and transmits a control signal to allow a transistor hysteresis reset signal to be transmitted to pixels of the display in the low grayscale region. A data driver transmits the transistor hysteresis reset signal to the pixels in the low grayscale region based on the control signal.
