1. A display panel driver comprising:
a driving controller configured to receive input image data and to convert the input image data into a data signal; and
a data driver configured to convert the data signal into a data voltage,
wherein the driving controller includes a plurality of lookup tables storing data signal values corresponding to grayscale values of the input image data based on an input maximum luminance, and
a total number of the data signal values stored in a first lookup table corresponding to a first input maximum luminance is different from a total number of the data signal values stored in a second lookup table corresponding to a second input maximum luminance.
