Mura compensation circuit and driving apparatus for display applying the same

A driving apparatus for a display, comprising:

• a restoring unit configured to restore display data from a data packet;
• a mura memory configured to store mura information comprising location information of a pixel having mura and compensation values for colors thereof;
• a gain adjustment unit configured to provide adjustment compensation values generated by applying an adjustment gain having an identical ratio to the compensation values for the colors of the pixel;
• a mura compensation unit configured to receive the display data of the colors of the pixel and to perform mura compensations on the display data of the colors of the pixel using the adjustment compensation values corresponding to the location information;
• a gamma circuit configured to provide a gamma voltage for each gray scale;
• a digital-to-analog converter configured to select a gamma voltage corresponding to the display data output by the mura compensation unit and to output the selected gamma voltage as an analog signal;
• and
• an output circuit configured to output a source signal for driving the analog signal.
