Abstract: A data compensation circuit includes a reference frame memory device which stores reference frame data, an accumulated stress memory device which stores cumulative stress data for each of pixels, a stress data generating block which compares output image data with the reference frame data to generate stress data for each of the pixels, a memory control block which adds the stress data to the cumulative stress data to update the cumulative stress data and a compensating block which generates the output image data by generating afterimage compensation data for each of the pixels based on the cumulative stress data and compensating input image data based on the afterimage compensation data.
