Abstract: A method of driving a foldable display device, which includes a first display panel and a second display panel that are foldable onto each other, includes detecting a first gaze angle of a viewer with respect to the first display panel and a second gaze angle of the viewer with respect to the second display panel, determining a first red, green, blue (RGB) luminance ratio corresponding to the first gaze angle and a second RGB luminance ratio corresponding to the second gaze angle based on a mapping table that stores expected gaze angles and optimal RGB luminance ratios mapped to the expected gaze angles, performing a first color shifting operation on the first display panel based on the first RGB luminance ratio, and performing a second color shifting operation on the second display panel based on the second RGB luminance ratio.

Abstract: An imaging apparatus an image sensor which generates a reference image data of a reference area that includes a measuring area in which a display panel is positioned and an image processor which determines the measuring area by analyzing luminance of the reference image data and generates a crop image data that includes a measuring image data of the measuring area.
