    摘要: A display device includes a display unit and a controller, the controller generating and transmitting a scan signal and an image data signal to a scan driver and a data driver, respectively. The controller includes a memory unit storing a look-up table of basic correction amounts for a test image data signal according a comparison result of comparing a measured value of an image of the display unit displaying the test image data signal with a target value of the test image data signal, and a data controller storing data for a modulation coefficient for applying the look-up table to the supplied image data signal, calculating a full correction amount corresponding to the supplied image data signal using the modulation coefficient and the basic correction amount of the look-up table, and outputting a corrected image data signal by correcting the supplied image data signal by the full correction amount.
