Abstract
A display driver includes: a compensator configured to divide an input image into a plurality of blocks having a plurality of columns and a plurality of rows, generate a first current map in which a current magnitude corresponding to each of the plurality of blocks has been calculated, generate a second current map based on a cumulative summation of the current magnitude of the block located on each column of the first current map in a column direction, and generate output data by compensating pixel values of the input image based on a third current map in which the current magnitude of the block located on each row of the second current map has been adjusted with respect to a position in a row direction; and a data driver configured to generate an output image based on the output data and provide the output image to a display panel.
