Abstract
A display driving circuit includes: a grayscale voltage generator configured to generate a plurality of grayscale voltages by linearly dividing a plurality of gamma tap voltages; a gamma correction module configured to calculate a compensation value with respect to an input pixel value by using a compensation model, and configured to apply the compensation value to the input pixel value to generate a compensated pixel value; and a data driver configured to receive the plurality of grayscale voltages from the grayscale voltage generator, and configured to output a data voltage corresponding to a grayscale voltage to a display panel, the grayscale voltage being selected from the plurality of grayscale voltages based on the compensated pixel value.
