The present application discloses a slidable flexible display device, including a first supporting body, a second supporting body, and a linkage mechanism. The first supporting body includes a first rear shell and a rear shell disposed on the first rear shell. The first supporting body and the second supporting body are slidable along a straight line between the first supporting body and the second supporting body. The linkage mechanism includes screw rod assemblies and a screen fixing plate. The first supporting plate and the screen fixing plate are respectively linked to the screw rod assemblies.

A mobile terminal is disclosed. The mobile terminal includes a body including a first body and a second body fastened to the first body, the second body separable from the first body, a flexible display including a first flexible display connected to the second body and located on a front surface of the body and a second flexible display connected to the first flexible display and located on a rear surface of the body, and a guide sheet positioned in a rear surface of the flexible display and providing the flexible display with an elastic force. At least a portion of the second flexible display is located on the front surface of the body when the second body is separated from the first body.

An electronic device is provided. The electronic device includes a flexible display including a first display area and a second display area that is transparent, a camera module including a first camera module and a second camera module, and at least one processor, wherein the at least one processor may be configured to execute a camera module application in a first state in which the second display area covers the first camera module, and when properties of a first transparent region are changed by adjusting an electrical signal with respect to the first transparent region of the second display area which abuts the first camera module, display an image received from the first camera module on a second transparent region of the first display area or a second transparent region of the second display area by reflecting the changed properties of the first transparent region for the image.

An electronic device is provided. The electronic device includes a housing including a first housing and a second housing connected to the first housing to slide within a designated range, a flexible display including a display panel and a reinforcing sheet, the flexible display including a first portion and a second portion extended from the first portion, and drawn in or out of the housing as the second housing moves with respect to the first housing, a circuit board, and a fingerprint sensor spaced from a rear surface of the flexible display, and disposed on the circuit board. The reinforcing sheet may include a first opening area disposed between the fingerprint sensor and the display panel with the second portion drawn in and a second opening area disposed between the fingerprint sensor and the display panel with the second portion drawn out.

An electronic device may include a housing including a first housing and a second housing to move relative to the first housing, a flexible display supported by at least one of the first housing or the second housing and changeable in form of a display area based on a movement of the second housing relative to the first housing, a board module disposed inside the housing, and a seating portion that forms a seating space receiving the board module and supports the board module.

An electronic device may include a housing including a first housing and a second housing configured to receive at least a portion of the first housing and move relative to the first housing, a display configured to be rolled or unrolled based on a slide of the housing, a display supporting member supporting at least a portion of the display, a motor structure including a motor core configured to generate a driving force for the slide of the housing and disposed in the housing, a first gear assembly connected to the first housing and a first end of the motor structure and configured to transfer at least a portion of the driving force generated by the motor core to the first housing, and a second gear assembly connected to the display supporting member and a second end of the motor structure, which is opposite to the first end, and configured to transfer at least a portion of the driving force to the display supporting member.

A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, a first rack, a second rack, a first gear, and a second gear. The first gear and the second gear rotate in conjunction with each other. The flexible display is divided into a first region and a second region, and the second rack forms a continuous loop together with the second region of the flexible display. Accordingly, when the second body slides with respect to the first body, tension can be stably applied to the flexible display, and the flexible display is prevented from being loosened.

The present specification provides a mobile terminal in which a display unit can expand, and a control method therefor. In the mobile terminal of the present invention, when an input signal detected by a sensing unit is equal to or larger than a threshold value, an operation that expands or contracts the display unit according to a touch drag direction is performed, thus allowing a user to intuitively control the mobile terminal. Further, there is an advantage in that the mobile terminal can be prevented from being dislodged from the user's hand while the display unit is in the process of expanding.

A mobile terminal that can be switched to a first state or a second state comprises: a first frame; a second frame that can be switched to the second state by sliding from the first frame in a first direction, and that can be switched to the first state by sliding in a second direction opposite to the first direction; and a low-friction sheet positioned on at least one side of an overlapping surface of the first frame and the second frame, wherein friction can be minimized during sliding of the mobile terminal, and thereby driving energy can be saved and noise generated by friction can be prevented.

A mobile terminal that can be switched from a first state to a second state by expanding in a first direction comprises: a body that can expand in the first direction; a display unit including a front part positioned on the front surface of the body, a rear part positioned on the rear surface of the body, and a side part which is positioned between the front part and the rear part and which encompasses the side surface of the body in the first direction; and a side frame which covers the side part of the display unit and which is coupled to the body, wherein, with respect to the side frame, the mobile terminal including a dustproof pad for removing foreign substances includes the side frame for covering the side part of the flexible display unit, and thus can prevent the display unit from being damaged.
