摘要： A Mura compensation data generation apparatus for compensating for Mura, and a Mura compensation apparatus of a display using Mura compensation data. The Mura compensation data generation apparatus includes an image representative value generation circuit configured to generate a representative value representing an entire gray of an image; a difference value extraction circuit configured to extract difference values between the representative value and gray values for a plurality of preset positions on the image; a distribution range determination circuit configured to determine a distribution range of the difference values by checking a maximum value and a minimum value of the difference values; and a Mura compensation data generation circuit configured to generate Mura compensation data having a preset number of bits corresponding to the difference values.
