Abstract
An operating method of an electronic device is provided. The method includes measuring an external temperature of the electronic device by using at least one sensor. The method may calculate, 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. The method may compare 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 first threshold temperature. The method may heat the variable region by controlling at least one of a luminance or a driving frequency of the variable region.
