Abstract: The present invention provides a display apparatus that improves the uniformity of luminance among a plurality of pixels and improves chromaticity by recalibrating artifacts of a display image recognized by a visual sensation even after calibration is performed, and a method of controlling the same. The display apparatus may include a display panel; a communication circuitry configured to receive an initial calibration coefficient value of a first pixel and at least one second pixel except for the first pixel of the display panel; and a controller configured to compare luminance of the first pixel and the second pixel based on the initial calibration coefficient value, to modify the initial calibration coefficient value based on the comparison result, and to control the display panel based on the modified calibration coefficient value.
