An accessory device for an electronic device is disclosed. The accessory device includes multiple sections, with one section holding the electronic device, and another section having an input mechanism, such as a keyboard. The accessory device includes a hinge assembly that allows relative movement of the sections with respect each other. An additional hinge assembly is integrated with the section carrying the electronic device, and provides additional flexibility and range of motion of the section, thereby allowing a user to position the electronic device at multiple different angles relative to the section carrying the input mechanism. Also, each hinge assembly may include multiple roller and spacer elements, as well as a retention structure passing through each roller element and spacer element. The retention structure can provide tension to increase the frictional force between the roller and spacer elements, and/or provide counterbalance to offset the weight of the electronic device.

According to various embodiments of the disclosure, an electronic device may includes: a first housing in which a display module is disposed; a second housing in which a circuit board and a cooling fan connected to the circuit board are accommodated, where a first opening is defined in the second housing to introduce air into the cooling fan; and a hinge module rotatably connected to the first housing and the second housing, and disposed adjacent to the first opening. The hinge module may includes: a hinge housing in which a first hinge opening is defined to be connected to the first opening; a first main gear disposed in the hinge housing and operably connected to the first housing; a second main gear operably connected to the second housing and configured to rotate in correspondence with the first main gear; a driving gear disposed adjacent to at least one of the first main gear or the second main gear and rotatable in correspondence with at least one of the first main gear or the second main gear; and a first cover plate disposed in the hinge housing and including a first rack gear area which meshes with the driving gear. The electronic device may be switchable between a closed state in which an angle formed by the first housing and the second housing is less than a predetermined angle and an open state in which the angle formed by the first housing and the second housing is equal to or greater than the predetermined angle. When the electronic device is in the closed state, the first cover plate is disposed to overlap with at least part of the first hinge opening. When the electronic device is in the open state, the first cover plate may be spaced apart from the first hinge opening, and the first hinge opening may be opened.

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.

A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

In an example, a card retainer may include a latch to removably engage with a free end of an expansion card. Further, a card retainer may include a pivot mount to attach the latch to a system board of a computing device. In some examples, the latch is movable about the pivot mount between an open position and a closed position. The latch may exert a bias force on the free end of the expansion card in order to retain the expansion card to the system board in a secure manner when the latch is disposed in the closed position.

A screenshot or screen capture operation method for an electronic device includes: capturing a screen displayed on a display; determining whether additional information exists on the displayed screen; when the additional information exists, extracting the additional information, based on the displayed screen; determining whether a command for modifying the captured screen has been received; when the command for modifying the captured screen is determined as having been received, modifying the captured screen according to a user input; and storing the extracted additional information and/or the captured screen as a captured image. The resulting method enables a user to capture a screen intended or desired by the user.

A foldable electronic device includes a first housing and a second housing that are foldable with respect to each other; at least one sensor; a display; a camera configured to operate in a first mode associated with user recognition, and a second mode associated with user authentication; a memory storing instructions; at least one processor configured to execute the instructions to: control the display to display notification information about an event corresponding to the foldable electronic device; based on a folding state of the foldable electronic device detected using the at least one sensor satisfying a predetermined condition, obtain at least one first image using the camera operating in the first mode; identify whether a face is present in the at least one first image; based on identifying that the face is present in the at least one first image, obtain at least one second image using the camera operating in the second mode; perform face recognition-based biometric authentication using at least part of the at least one second image; and based on the biometric authentication being successful, control the display to display content corresponding to the event.

A control method of an apparatus is provided. The apparatus includes a control unit coupled to a proximity sensor to detect a first distance of a user in a field of view, and coupled to a charge variation sensor to detect an electric/electrostatic charge variation caused by the user in a detection region. The control method includes acquiring a charge variation signal and generating charge variation parameters as a function of the charge variation signal. The control method further includes determining whether a condition on charge variation parameters is verified, and if the condition on charge variation parameters is verified, activating the proximity sensor and acquiring a proximity signal. Proximity parameters are generated as a function of the proximity signal. If a condition on proximity parameters is verified, one or more functionalities of the apparatus are activated.

A connection device includes two adjacent connectors, a first connecting portion, and a second connecting portion. The two adjacent connectors are configured to support a flexible member. The first connecting portion of a first connector of the two adjacent connectors is rotatably connected to the second connecting portion of a second connector of the two adjacent connectors. The first connector rotates relative to the second connector based on relative rotation between the first connecting portion and the second connecting portion. The two adjacent connectors rotate to a first limit position and a second limit position based the relative rotations between the first connector and the second connector.
