An electronic device is described that includes a first body; a second body; and a connection member through which the first body is connected with the second body. The connection member includes a rotary connection part for supporting the first body to rotate around an axis line of the rotary connection part and an extensible connection part for supporting the first body to be close to or away from the second body.

There is disclosed a mobile terminal including a curvedly flexible display unit, a case having a case to which the display unit is coupled, wherein the case includes a first case, a second case coupled to the first case to rotate with respect to the first case in a preset range of angles, a hinge shaft provided in the first case, a hinge housing provided in the second case, the hinge housing in which the hinge shaft is disposed, with a cylindrical shape, and a stopper for adjusting a rotation angle between the first case and the second case. The curvature of the mobile terminal may be variable and that it may be convenient to hand-carry the mobile terminal. In addition, the user can change the curvature he or she can feel comfortable. Even when a force is applied to an end of the mobile terminal, the damage on the mobile terminal can be prevented.

A telecommunication device includes a casing, smart phone components disposed within the casing, two opposed flexible wrist grips having upper and lower surfaces, and a flexible screen disposed on the lower surfaces of the casing and the opposed flexible wrist grips and in communication with the smart phone components.

The flexible printed circuit assembly includes a flexible printed circuit and a control structure. The control structure includes a transmission member and two reels arranged on the transmission member at an interval. The flexible printed circuit passes between the two reels. The transmission member is configured to drive the two reels to rotate, so that the flexible printed circuit is wound on entire peripheral sides of the two reels. Alternatively, the control structure includes a transmission member, a guide shaft, and a connecting member. The guide shaft is located on a side of the flexible printed circuit. The connecting member has one end arranged on the transmission member and another end connected to the guide shaft. The transmission member is configured to drive the connecting member to drive the guide shaft to move, and the guide shaft is configured to drive the flexible printed circuit to bend.

In aspects of rollable screen device thermal mitigation, a mobile device can be configured in a compact form factor and in an expanded form factor. The mobile device includes at least one heat source that generates heat within the mobile device. The mobile device implements a configuration manager that initiates expanding the mobile device from the compact form factor to the expanded form factor based at least in part on one of a thermal load, a device temperature, or a device component temperature. The mobile device can be a foldable mobile device, or an expandable mobile device with a rollable display screen configurable in one of multiple display states corresponding to respective device form factors.

Disclosed is an electronic device. The electronic device disclosed herein comprises a first housing and a second housing, a hinge rotatably connecting the first housing and the second housing, a flexible display exposed through a first portion of the first housing and a second portion of the second housing, at least one sensor, a camera, a communication module, memory storing instructions, and a processor. The instructions, when executed by the processor, cause the electronic device to run a first application for controlling the camera, identify a folding angle of the electronic device through the at least one sensor, and, on the basis of the folding angle being within a designated range excluding 0 degrees and 180 degrees while the first application is running, transmit, to an external electronic device, a command for displaying an icon related to the first application on a display of the external electronic device connected through the communication module.
