ELECTRONIC DEVICE INCLUDING FLEXIBLE DISPLAY, AND CONTROL METHOD THEREOF

An electronic device according to an embodiment may comprise: a display module including a flexible display; a driving unit for changing a size of a display screen where the flexible display is exposed to the outside of the electronic device; and a power management module for supplying power to the electronic device. The electronic device may determine whether a condition for restricted booting for controlling the driving unit is satisfied in case that power is applied to the electronic device, operate in a restricted booting state in which an operation system is not booted in case that the condition for restricted booting is satisfied, and adjust the size of the display screen of the flexible display by controlling the driving unit through the power management module in the restricted booting state. Various other embodiments may also be possible.
