TECHNICAL FIELD One or more embodiments relate to an electronic device and a method of operating the electronic device, and more particularly to, an electronic device capable of preventing an afterimage of a display device, and a method of operating the electronic device. BACKGROUND ART When display devices display the same image at the same location for a long time, afterimages may occur. In particular, in the case of organic light emitting diode (OLED) display devices, afterimages easily occur, and various afterimage prevention technologies may be used to solve this problem. For example, pixel shift may be used to provide afterimage prevention. Pixel shift is a technology which moves the location of a screen displayed on a display device by a specific pixel in a specific direction over time, which prevents the same image from being displayed at the same location for a long time, thereby reducing the occurrence of afterimages.
