Original Abstract Submitted
a display device may include a plurality of subpixels respectively connected to a plurality of data lines; a data driving circuit configured to convert a compensated digital image data into an analog data voltage and to supply the analog data voltage to the data lines; a large-capacity memory configured to store initial compensation data based on a characteristic value for each of the plurality of subpixels; a high-speed memory configured to store sampled compensation data sampled from the initial compensation data for less than all of the plurality of subpixels in one frame; and a timing controller configured to control the gate driving circuit and the data driving circuit, to determine final compensation data based on at least one of the sampled compensation data and the initial compensation data, and to output the compensated digital image data based on an input image data and the final compensation data.
