Abstract: A correction data generating apparatus, a method of generating correction data, and an image quality correction system are provided. The method of generating correction data includes detecting brightness of a display panel, determining an non-uniform area of the display panel for each RGB color based on the detected brightness, generating correction data regarding the non-uniform area by determining a screen split size and a correction section for correcting an image quality of the display panel based on the non-uniform area, and storing the generated correction data. In this case, the correction data is stored in a storage of a display apparatus controlling the display panel, and the display apparatus corrects an image quality of the display panel using the correction data.
