Abstract
A display apparatus includes a display including display modules, a storage configured to store a correction coefficient of each of light emitting pixels included in each of the display modules, and a processor configured to apply the correction coefficient of each of the light emitting pixels respectively to a pixel value of each of the light emitting pixels to correct the pixel value of each of the light emitting pixels. The correction coefficient of each of light emitting pixels is determined based on a first target value for uniformity between pixels, and the first target value is determined based on one or more representative pixel values of the display modules.
