Abstract: A method of driving a display device includes a writing operation and a reading operation. The writing operation includes writing first to Mth frame data in a first frame memory during first to Mth frame periods. The reading operation includes reading (L−M)th and (L−M+1)th frame data among the first to Mth frame data from the first frame memory during an Lth frame period. M may be three or more, and L may be an integer ranging from (M+1) to (2M−1). The frame data read from the first frame memory corresponds to an image to be displayed. Reading and writing operations are further performed for remaining ones of the frame memories.

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.
