Abstract
A display panel driver includes a reference register, a calculator, and a data signal generator. The reference register stores a reference compensation gamma data curve generated by compensating a luminance characteristic deviation of a display panel in a reference luminance mode. The calculator calculates a compensation gamma data curve for each of a plurality of luminance modes based on the reference compensation gamma data curve to perform a dimming operation. The data signal generator generates data signals corresponding to input grayscale levels based on the compensation gamma data curve.
