A mobile terminal comprises a display unit that may be subjected to bending deformation in a first direction, and a rolling plate attached to a rear surface of the display unit, enabling bending deformation to correspond to bending deformation of the display unit, wherein the rolling plate includes a plurality of support bars extended in a second direction vertical to the first direction and arranged in parallel in the first direction, and an expanded side portion arranged at an end portion of the plurality of support bars, and the expanded side portion includes a guide bump engaged with its adjacent expanded side portion. Since the rolling plate supporting the display unit is not twisted by rotation, the display unit may maintain a flat state.

The disclosure discloses an electronic device including a flexible display having an expandable display area. The disclosed electronic device may include: a housing including a first cover disposed to face a first direction, a second cover disposed to face a second direction opposite to the first direction, and a side member enclosing at least part of a space between the first and second covers; a slider to be inserted or withdrawn by being disposed to at least part of an area of the first cover of the housing; a flexible display disposed in the slider such that at least part thereof is exposed, and disposed to allow a display area to be expanded according to the withdrawing of the slider and allow the expanded display area to be hidden inside the housing; and a support body mounted closely in contact on a bottom face of the flexible display, supporting the expanded display area as a prop when the slider is withdrawn, and disposed to be housed inside the housing together with the expanded display area when the slider is inserted.

A portable electronic device is provided. The portable electronic device includes a front glass cover that forms the front of the electronic device, a back cover that forms the back of the electronic device, a bezel that surrounds the space formed between the front and back covers and is formed integrally with, or separately from, the back cover, wherein the bezel has a first opening with a first size and a second opening with a second size smaller than the first size, the second opening being disposed adjacent to the first opening, a display device that is located in the space and has a screen area exposed through the front cover, a tray structure that is inserted into the space through the first opening and is detachably mounted, the tray structure having a recess in which a memory card and/or a subscriber identification module (SIM) card is received, a first member that holds the tray structure when the tray structure is inserted into the space and a second member that allows a first member to release the tray structure by the press of an external member that is inserted through the second opening, and a waterproof structure that includes a first portion that is movably inserted into the second opening, a first end portion that makes contact with the second member by the press of the external member, and a second end portion that is pressed by the external member.

A display device includes a display module which is foldable and includes a first non-folding area, a folding area and a second non-folding area, in order, a first plate corresponding to the first non-folding area, a second plate corresponding to the second non-folding area and spaced apart from the first plate, and a cover film facing the display module with both the first plate and the second plate therebetween. The cover film includes a first film corresponding to each of the first non-folding area, the folding area and the second non-folding area, the first film attached to each of the first and second plates, and at the folding area, a second film attached to the first film. The display module which is folded disposes the second film between the first film and the first plate and between the first film and the second plate.

Disclosed is a flexible display apparatus characterized by comprising: a first body; a flexible display configured to be inserted into the first body or withdrawn from the first body, while being deformed by an external force; a second body coupled to one end of the flexible display; and a rear surface plate coupled to a rear surface portion of the flexible display and configured to deform together with the flexible display, wherein the flexible display deforms so as to be windable while being inserted into the first body, and deforms so as to be unfolded while being withdrawn from the first body.

An extension device, including a connecting base and an anti-theft lock assembly, is provided. The connecting base includes a housing, a first moving member, a fixed member, and a second moving member. The fixed member is disposed at one side of the housing and includes a lock hole. The second moving member is movably disposed between the first moving member and the fixed member. The anti-theft lock assembly is detachably disposed at one side of the fixed member opposite to the second moving member. The anti-theft lock assembly is adapted to pass through the lock hole of the fixed member and push against the second moving member, so that the second moving member abuts against the first moving member to stop the first moving member at a buckling position. In addition, an electronic system, including the extension device, is also provided.

An electronic device includes a first part. The electronic device also includes a second part that is configured to move with respect to the first part. The electronic further device includes a magnetic member that is disposed on one of the first part and the second part. Additionally, the electronic device includes a sensor that is disposed on the other one of the first part and the second part and facing the magnetic member. The magnetic member includes a body extending in a movement direction of the second part and magnets respectively disposed at both ends of the magnetic member such that different polarities are close to each other.

A display device includes a base panel and one or more auxiliary panels that are positionable between a hidden configuration behind the base panel and a visible configuration at a side of the base panel. The display device is communicatively connectable to a host computing device. Each auxiliary panel positioned in the visible configuration is exposed to the host computing device as part of one display along with the base panel or as a separate display, depending on the side of the base panel at which the auxiliary panel has been positioned and/or depending on the auxiliary panel that has been positioned.

A mobile terminal comprises a display unit that may be subjected to bending deformation in a first direction, and a rolling plate attached to a rear surface of the display unit, enabling bending deformation to correspond to bending deformation of the display unit, wherein the rolling plate includes a plurality of support bars extended in a second direction vertical to the first direction and arranged in parallel in the first direction, and an expanded side portion arranged at an end portion of the plurality of support bars, and the expanded side portion includes a guide bump engaged with its adjacent expanded side portion. Since the rolling plate supporting the display unit is not twisted by rotation, the display unit may maintain a flat state.

A support assembly, a foldable display screen and a terminal device are provided. The support assembly includes a first support member, a second support member and a third support member. The second support member has a first side and a second side. The first support member is rotatably arranged to the first side of the second support member, and the third support member is rotatably arranged to the second side of the second support member. The first support member is movable between a first locked position and a first unlocked position. The first support member is configured to rotate relative to the second support member, and the second support member and the third support member are configured to be fixed relative to each other when the first support member is in the first locked position. The second support member is configured to rotate relative to the third support member when the first support member is in the first unlocked position.
