Abstract: An electronic device includes a display driver integrated (DDI) circuit configured to output reference pixel values to be used to obtain target pixel values of a first line, and to output image pixel values associated with a target image; and a panel circuit configured to include the first line that includes pixels configured to display a reference image having the target pixel values, based on the reference pixel values, and a second line that includes pixels configured to display an image corresponding to the target image, based on the image pixel values. The DDI circuit may be further configured to compensate for the image pixel values based on differences between the image pixel values and the reference pixel values.
