    Abstract: A display apparatus includes a first compensator, a second compensator and a display panel including pixels. The first compensator generates a first compensation coefficient based on sensing data of a pixel of the pixels for a first grayscale value, generates a second compensation coefficient based on camera imaging data for a second grayscale value greater than the first grayscale value and compensates image data based on the first compensation coefficient and the second compensation coefficient. The second compensator compensates the image data by modeling sensing data of entire grayscale range based on sensing data of the pixel for a third grayscale value and a fourth grayscale value. The display panel displays an image based on the image data compensated by the first compensator and the second compensator.
