1. An operating method of an electronic device, the method comprising:
measuring an external temperature of the electronic device by using at least one sensor;
calculating, from an entire region of a flexible display, a fixed region that is visually exposed to an outside regardless of a screen size of the electronic device, and a variable region that is visually exposed at least in part to the outside in a screen expansion or screen size change state of the electronic device;
comparing the external temperature with a preset first threshold temperature, thereby determining heating of the variable region in response to the external temperature being less than the preset first threshold temperature; and
heating the variable region by controlling at least one of a luminance or a driving frequency of the variable region.
