An electronic device includes a first display driver configured to control a first display, a second display driver configured to control a second display, and a processor. The processor is configured to: if screen switching is detected while displaying first image data on the first display using a first pixel value, produce a first calibration value based on the difference between the first pixel value for display on the first display and a second pixel value for display on the second display; apply the first calibration value to the second pixel value so as to produce a third pixel value corresponding to the first pixel value; and control the second display driver so as to display the first image data on the second display using the third pixel value. Various other embodiments may be provided.
