Display apparatus and method of compensating gamma value of the same

A display apparatus comprising:

• a display panel comprising a first display area and a second display area;
• a first gamma controller configured to adjust luminance of first input image data of the first display area, color coordinates of the first input image data, luminance of second input image data of the second display area and color coordinates of the second input image data;
• and
• a second gamma controller serially connected to the first gamma controller and configured to adjust the luminance of first input image data and the color coordinates of the first input image data and configured not to adjust the luminance of second input image data and the color coordinates of the second input image data.

A method of compensating a gamma value of a display apparatus, the method comprising:

• calculating color coordinates of first image data of a first display area of a display panel;
• calculating color coordinates of second image data of a second display area of the display panel;
• and
• adjusting luminance of the first image data, the color coordinates of the first image data, luminance of the second image data and the color coordinates of the second image data.
