An electronic device is provided. The electronic device includes a hinge module, a first housing at least partially coupled to a first side of the hinge module and including a first antenna, a second housing at least partially coupled to a second side of the hinge module, configured to be foldable and unfoldable with the first housing by using the hinge module, and including a second antenna, a sensor circuit configured to detect an unfolding state and/or a folding state of the first housing and the second housing, a processor operatively connected to the first antenna, the second antenna, and the sensor circuit, a first signal line configured to connect the processor and the first antenna, a tuner circuit disposed on the first signal line, and a second signal line configured to connect the processor and the second antenna, wherein the processor is configured to, in case that the first housing and the second housing are detected to be in the folding state by using the sensor circuit, receive feedback of a signal transmitted to the second antenna, detect a phase of the feedback signal, and determine a time constant of the tuner circuit disposed on the first signal line, based on the detected phase of the signal.

The present invention relates to a flexible display apparatus which comprises: a body part having a polygonal prism shape; a flexible display part deformed by external force; and a frame part, which includes a plurality of segment plates arranged in parallel to one another, supports the flexible display part, and is configured to be wound around the outer surface of the body part or unwound, wherein, when the frame part is wound, the segment plates are disposed to surround the body part in a manner corresponding to a rolling radius, and when the frame part is unwound, segment plates neighboring each other come into close contact with each other.

Provided are a screen component, a mobile phone, and a mobile device. The screen component includes: a screen body, wherein a presentation area is provided on an end of the screen body; and a driving mechanism, wherein the driving mechanism is configured to drive the screen body to switch between a first position and a second position. While the screen body is arranged in the first position, the presentation area is located within a range of a window, and a front-mounted mechanism is able to expose from the presentation area; and while the screen body is arranged in the second position, the screen body takes up the window, and the front-mounted mechanism is shielded by the screen body.

The present invention relates to a mobile terminal and a method for controlling same, and more particularly, provides a mobile terminal and a method for controlling same, the mobile terminal comprising: a body including a first body and a second body; a first camera and a second camera included in the body; displays coupled to the body and outputting images; and a control unit. The control unit outputs video previews to the display of the first body and outputs, to the display of the second body, a camera application for controlling the video previews that are being output, wherein the video previews include a first video preview captured by the first camera and a second video preview captured by the second camera.

A vehicle control system using a swivel operation of a smart device may include: a smart device mounted on a holder within a vehicle; and a control unit configured to receive swivel data according to a swivel operation performed to the smart device, and change and display a vehicle function control screen.

The present invention relates to a protective case for foldable mobile devices. The folding case according to the present invention comprises a first case and a second case, wherein the folding case further comprises a side cover which rotates by an elastic part as the foldable mobile device is folded or unfolded, and provides a full protection for the entire foldable mobile device including each corner of its hinge part. The folding case according to the present invention covers the hinge part smoothly without any unfavorable space or gap, and it provides the satisfaction with the use and the beauty of the overall appearance as the users would conceive that the two separated case parts and the hinge part operates as if those parts form one united case.

Disclosed are a method for playing sound and a multi-screen terminal. The method includes: detecting, by a multi-screen terminal, a current opening/closing angle or angles between the respective display screens; and selecting, by the multi-screen terminal according to the detected current opening/closing angle or angles, a group of prestored audio drive parameters, and outputting the group of audio drive parameters to a power amplification module of the multi-screen terminal; or, determining whether the current opening/closing angle or angles and the current audio drive parameters are respectively prestored opening/closing angle or angles and audio drive parameters corresponding to an optimal sound field playing effect, and if not, giving a prompt as to whether to adjust the opening/closing angle or angles between the respective display screens and/or the current audio drive parameters.
