1. A display apparatus comprising:

  • a display panel configured to display an image;

    a position detector configured to determine a position of a user;

    a driving controller configured to generate an overdriving value according to a grayscale value of previous frame data and a grayscale value of present frame data;

    a gate driver configured to output gate signals to the display panel; and

    a data driver configured to output data voltages to the display panel based on the overdriving value,wherein the driving controller is further configured to;

    receive a plurality of overdriving data of a plurality of viewing angles;

    determine a fixed parameter based on the plurality of overdriving data of the plurality of viewing angles;

    determine a viewing angle of the user based on the position of the user;

    determine a variable parameter based on the fixed parameter and the viewing angle;

    generate an overdriving reference line based on the fixed parameter and the variable parameter;

    receive shift overdriving data generated for a grayscale value which is different from the grayscale value of each of the plurality of overdriving data;

    determine a shift value of the overdriving reference line according to grayscale values based on the shift overdriving data; and

    generate the overdriving value based on the overdriving reference line and a shifted overdriving reference line.
