1. A luminance correction system comprising:

  • a data signal application module that applies a data signal to a display region to emit light at a maximum luminance;

    a luminance measurement module that measures luminance of a pixel in the display region to which the data signal is applied;

    a comparator that compares the measured luminance with a target value of luminance to obtain a difference value therebetween;

    a memory that stores a lookup table including luminance variations of R, G, and B pixels in the display region corresponding to the obtained difference value;

    a data adjustment module that adjusts the data signal depending on the stored luminance variations of the R, G, and B pixels and transfers the data signal to the data signal application module;

    a color coordinate judgment module that judges a color coordinate of the of the R, G, and B pixels; and

    a chroma correction module that controls chroma of the R, G, and B pixels corresponding to the color coordinate judged by the color coordinate judgment module.
