Abstract: An electronic device is provided. The electronic device includes a processor operatively connected to a connector, a power supply circuit, a discharge circuit, a first switch, and a second switch, and configured to detect a connection of an external electronic device through the connector in a state in which the discharge circuit is activated, perform first discharge of discharging a current of the connected external electronic device using the discharge circuit for a designated time based on the connection of the external electronic device, control the first switch to cut off the electrical connection between the discharge circuit and the ground after performing the first discharge, control the second switch to electrically connect the connector and power supply circuit to supply designated power to the external electronic device through the connector, and perform communication with the external electronic device based on a communication connection with the external electronic device.

Abstract: This electronic device may comprise: a flexible display; a first rolling actuator configured to extend the flexible display in a first direction; a second rolling actuator configured to extend the flexible display in a second direction opposite to the first direction; and at least one processor. The at least one processor may be configured to: determine the mounting state of the electronic device; acquire information about the position of a peripheral device, which is linked with the electronic device, based on the mounting state satisfying a designated condition; set the extension direction of the flexible display on the basis of the information about the position of the peripheral device; and control the first rolling actuator and/or the second rolling actuator to extend the flexible display in the first direction and/or the second direction on the basis of the set extension direction.

Abstract: At least one processor included in an electronic device can acquire first motion data about the motion of the electronic device through at least one motion sensor, acquire second motion data about a motion of an external device through a connector included in the electronic device, determine, on the basis of the first motion data and the second motion data, the folding angle between the electronic device and the external device connected to the electronic device, and determine, on the basis of the determined folding angle, an input mode that sets whether to display a user interface on a display or whether to block an input signal received through the connector. Various other embodiments identified through the specification are possible.
