Abstract: A method of generating compensating data for a pixel circuit differences in a display device includes displaying a test image of pixels of the display device; generating a first camera image by photographing the test image; applying a test input signal to each of the pixels and sensing corresponding test outputs, wherein the test input signal is at least one of a test current and a test voltage; generating weights for the pixels based on the test outputs; generating a second camera image by applying the weights to the first camera image; and generating compensation data for the pixels based on the second camera image.

Abstract: In a method of generating correction data for each of a plurality of display devices, a characteristic distribution for initial display devices among the plurality of display devices may be obtained, center characteristic compensation data may be generated based on the characteristic distribution for the initial display devices, the center characteristic compensation data may be applied to subsequent display devices that are subsequent to the initial display devices among the plurality of display devices, mura correction data and image quality correction data may be generated by performing mura correction and image quality correction on each of the subsequent display devices to which the center characteristic compensation data are applied, and the center characteristic compensation data, the mura correction data and the image quality correction data may be written into each of the subsequent display devices.
