Display apparatus and method for driving the same

A method for driving a display device comprising a display panel comprising a plurality of pixels, a timing controller for correcting an input image signal and transmitting the input image signal to the display panel, and a memory for storing model correction data for correcting a gray value corresponding to respective models of a plurality of timing controllers, and for storing image quality correction data for correcting a gamma deviation of the display panel, the method comprising:

• determining identification information of a timing controller;
• reading model data according to the identification information of the timing controller from among the model correction data;
• determining identification information of the display panel;
• reading the image quality correction data by using the identification information of the display panel;
• and
• generating final correction data by using the model correction data and the image quality correction data.
