Abstract: A display apparatus includes a display panel comprising a plurality of data lines and a plurality of gate lines crossing the plurality of data lines, and a memory configured to store a plurality of gamma voltage data respectively corresponding to a plurality of partial areas of the display panel, the plurality of gamma voltage data for compensating a gamma difference between the partial areas of the display panel. The display apparatus further includes a timing controller configured to read, from the memory, the plurality of gamma voltage data respectively corresponding to the plurality of partial areas, and a plurality of data driver circuits configured to generate, based on the plurality of gamma voltage data, a plurality of grayscale voltages to be applied to the plurality of data lines in the plurality of partial areas.
