The present disclosure provides a hinge and a mobile terminal. The hinge includes at least two joints that are sequentially connected. Each joint includes a joint body, a rotation structure provided at a first end portion of the joint body, and a position-limit structure provided at a second end portion of the joint body. The rotation structures of any adjacent two joints are socketed with each other. The rotation structures of adjacent two joints are capable of rotating relative to each other. The adjacent two joints are opened or closed via relative reciprocating motion between the position-limit structures of the adjacent two joints. When an opening degree of the adjacent two joints reaches a preset value, the position-limit structures of the two adjacent joints stop each other.

An electronic device includes a flexible display, a housing assembly, and an adhesive layer assembly fastened between the flexible display and the housing assembly. The adhesive layer assembly includes a strong adhesive layer and a weak adhesive layer, and a stiffness of the strong adhesive layer is higher than a stiffness of the weak adhesive layer. The strong adhesive layer and the weak adhesive layer are arranged to make the flexible display deform with the electronic device.

An electronic device is provided. The electronic device includes a base housing, a sliding housing and that is coupled to the base housing so as to slide, a folding housing that at least partially overlaps the base housing and that is connected to the sliding housing, a display disposed on the folding housing and the sliding housing, a rolling module that is coupled to a rear surface of the display, and a hinge module connected to the folding housing and the sliding housing. The electronic device is configured to be capable of a sliding operation in which the folding housing and the sliding housing move in a sliding direction to extend or retract a display region of the electronic device and a folding operation in which the folding housing is folded or unfolded relative to the sliding housing to fold or unfold a portion of the display region.

One or more computer processors detect a computing device within a proximity to a rollable device. The one or more computer processors determine a location and an orientation of the rollable device relative to the computing device. The one or more computer processors attach the rollable device to the computing device utilizing the set of biometric locks engaged programmatically such that at least one side of the rollable device is locked and hinged to the computing device. The one or more computer processors responsive to the rollable device attached to a side of the computing device, extend a display area of the computing device to the rollable device.

A foldable electronic device includes a central body, a linkage unit, a plurality of operating mechanisms, and a plurality of panel bodies. The linkage unit includes a plurality of driving shafts. Each of the operating mechanism has a wing rod, a lifting plate, and a connecting rod. The wing rod is fixed to the lifting plate. The wing rod and the connecting rod pivotally connecting to the central body and the driving shaft respectively. When the panel bodies are in a folded status, a flexible screen is bent, and the wing rod, the lifting plate, and the central body collectively define a yielding space for accommodating a flexible section of the flexible section. The supporting plate at the bottom of the flexible screen has a weakening structure corresponding to the flexible section.

An electronic device includes: a first housing; a second housing; at least one hinge device which connects the first housing and the second housing to be foldable with respect to each other with reference to a folding axis; a hinge housing which receives the at least one hinge device; a flexible display including a first region corresponding to the first housing, a second region corresponding to the second housing, and a folding area which is foldable and connects the first region and the second region; and at least one protective member which is coupled, in an area corresponding to the folding area, to the hinge housing to be rotatable with reference to a rotation axis parallel to the folding axis, the protective member including a material which is at least partially deformable according to a folding operation of the electronic device, wherein the at least one protective member at least partially overlaps at least one edge of the flexible display in the folding area when the flexible display is viewed from above.

The foldable mobile phone having an ePaper display added on a mobile phone through mechanical and electronic means so that the ePaper display shares the mobile phone's various mechanical and electronic units. The mechanical means allows the ePaper display to be folded towards or unfolded from the mobile phone. The electronic means allows various data such as text, pictures, videos to be shown from the mobile phone on the ePaper display. The ePaper display enhances the mobile phone's applicability and reduces harm to the eyes.

According to various embodiments of the disclosure, an electronic device may include: a first housing, a second housing rotatably coupled with the first housing and configured to rotate between a first position at which the second housing at least partially faces the first housing and a second position at which the second housing is unfolded at a specified angle from the first position, a hinge module including a hinge providing at least one folding axis and rotatably coupling the first housing and the second housing about the folding axis, and a hinge cover disposed between the first housing and the second housing and coupled to surround at least a part of the hinge module, and at least one part of the hinge cover may be configured to be located closer to the hinge module at the second position than at the first position.

A display device includes a display panel including a front surface that displays an image, and a rear surface, wherein the display panel is foldable with respect to a folding axis extending in a first direction; and a metal plate disposed on the rear surface of the display panel, wherein the metal plate includes a first body and a second body that are arranged in a second direction intersecting the first direction; a patterned portion disposed between the first body and the second body to overlap the folding axis in a thickness direction of the display device; and at least one protrusion protruding parallel to the folding axis from an edge of at least one of the first body, the second body, and the patterned portion.

A foldable screen includes a screen assembly and a housing assembly, the housing assembly includes at least three housings, and the screen assembly covers the at least three housings. The foldable screen includes linked connection assemblies, any two adjacent housings in the at least three housings are connected by the linked connection assemblies, and the at least three housings are unfolded or folded relative to each other at the same time by the linked connection assemblies.
