Abstract: A display device includes a timing controller for controlling the display of an image. The timing controller forms a frame for an image signal based on a main frame, a compensation frame, and at least one blank frame. The timing controller also determines a driving method for the display pixels to generate output image data. The main frame serves to display the image signal. The compensation frame serves to compensate luminance of the main frame. The blank frame serves to express a black gray scale value.
