Abstract

A display device correction method is provided for correcting luminance unevenness in a display device including pixels, which are arranged in a matrix and include light-emitting elements that emit light according to a luminance signal. The method includes obtaining in advance first correction data, which includes correction data components each corresponding to a different one of the pixels and is for correcting the luminance signal. The method also includes transforming the first correction data into second correction data by decomposing the correction data components included in the first correction data into frequency components, and removing a predetermined frequency component among the frequency components. The method further includes correcting the luminance signal using the second correction data.
