1. A method of driving a display panel, comprising:

  • providing a control signal and a grayscale signal, the control signal comprising a gate clock signal and a data clock signal;

    providing a gate signal to the display panel based on the gate clock signal;

    dividing the display panel into blocks according to distance from a light source to each of the blocks;

    outputting a compensating signal of an n-th frame using look-up tables, the look-up tables respectively corresponding to the blocks of the display panel, and “

    n”

    being a natural number; and

    converting the compensating signal of the n-th frame into a grayscale voltage and providing the grayscale voltages to each corresponding block of the display panel.
