a display panel which displays an image;
a current compensator which calculates a load for input image data, compensates the input image data to output compensation image data having a target current corresponding to the load; and
a panel driver which drives the display panel based on the compensation image data,
wherein the current compensator calculates the load for the input image data based on a combination of load weights calculated by different variables,
wherein the input image data includes a plurality of grayscales and a plurality of colors,
wherein the load weights include grayscale load weights, and each of the grayscale load weights is calculated based on maximum current data for each grayscale of the grayscales for each color of the colors included in the input image data.
