Abstract: An electronic device is provided. The electronic device includes a heat generation source including a heat dissipation surface dissipating heat, a support member disposed on a lateral side of the heat dissipation surface and surrounding at least a part of the heat generation source, a heat dissipation member facing the heat dissipation surface of the heat generation source and disposed so as to cover an area in which the support member is disposed, a thermal interface material disposed between the upper part of the heat dissipation surface of a heat generation surface and the lower surface of the heat generation source, and supported by the support member, and an adhesive member disposed in the area in which the thermal interface material is supported by the support member between the thermal interface material and the heat dissipation member, and for coupling the thermal interface material and the heat dissipation member.

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.
