1. A method of compensating for an output of a data driver of a display device, the method comprising:
measuring a first output value of a sensing circuit that senses pixels by applying an external voltage to the sensing circuit;
measuring second output values of the sensing circuit by applying output voltages within an output range of the data driver to the sensing circuit through output amplifiers of the data driver;
generating a compensation look-up table based on the first output value and the second output values; and
compensating for the output voltages of the data driver based on the compensation look-up table.
