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.
