A key structure includes a key cap, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. The first hinge part has a first pivot coupling portion and a first connecting portion. The second hinge part has a second pivot coupling portion and a second connecting portion, wherein the first and second connecting portions are connected on an axis, and the first and second hinge parts rotate with respect to the axis. The first and second supporting parts are coupled to two ends of the first and second pivot coupling portions, respectively. The attractable element is disposed on the second hinge part. The magnet is correspondingly located under the attractable element for providing a magnetic force, so that the attractable element is attracted and positioned by the magnetic force.

A key structure includes a supporting plate, a movable plate, a keycap and a limiting structure. The supporting plate has supporting plate opening. The movable plate has a movable plate opening. The supporting plate is disposed over the movable plate. The keycap is disposed over the supporting plate. The limiting structure is disposed on the keycap and inserted in the supporting plate opening. When the movable plate is moved to a disabled position, the limiting structure is not aligned with the movable plate opening and the limiting structure in the supporting plate opening is stopped by the movable plate. Consequently, the keycap is not allowed to be moved.

A portable computing device may include a lid and a base. The lid may include a display on a front side of the lid. The base may be rotatably attached to the lid. The rotatable attachment of the base to the lid may enable the lid to rotate from an open position in which the lid is rotated away from the base to a tablet position in which a back side of the lid faces a bottom side of the base. The base may include a keyboard on a top side of the base and an elastic sheet extending over the keyboard. The keyboard may include keys configured to retract into the base in response to the lid rotating to the tablet position and extend out of the base in response to the lid rotating out of the tablet position.

Proposed is a key switch haying a collapsible balance frame, comprising: a base, a movable plate, a balance frame, a transmission member and a key cap, wherein the movable plate is installed on the base and moves left and right along the base, wherein the balance frame is provided over the movable plate, wherein the balance frame comprises a first bracket and a second bracket arranged on a first side and a second side of the balance frame, respectively, wherein a lower end of the first bracket is connected to the movable plate, and a lower end of the second bracket is connected to the base, wherein a return spring is arranged horizontally, first and second ends of the return spring are (i) respectively connected to the first and the second brackets or (ii) respectively connected to the key cap and any one of the first bracket and the second bracket.

A multiple monitor apparatus in the form or a laptop PC, a desktop monitor, a mobile device, and the like. In dual screen mode, the additional monitor is typically presented displaying different content and centered to the user. In single screen mode, the additional display enclosures are retracted and stored in such a manner that they do not present themselves to the user. A guiderail assembly is used to center both display enclosures relative to the user. The guiderail assembly may be motorized or manually effected and may be located above or below the primary enclosure hinge. The secondary enclosure may be extended and retracted from the primary enclosure by the use of slider arms. The secondary enclosure may also be hinged to the primary enclosure, utilize pegs, ride on its own guiderail, and detach from the primary enclosure or the apparatus. Independent guiderails may also be employed to center two or more displays relative to a user. In one embodiment, the monitor may be rotated from landscape to portrait view.

The description relates to devices and/or device accessories. One example can include a Hall effect sensor configured to sense magnetic fields along a sensing axis and a pair of elongate magnets having co-axial and opposite magnetic axes that are perpendicular to the sensing axis.

A controlling device has a configurable key. An insert is provided to the configurable key and includes an indicium representative of a media content provider. An image of the indicium or an image of a QR code associated with the indicium is used to assign one or more commands to the configurable key. The one or more commands are used to cause a controllable device to tune to a channel on which the media content provider is being broadcast, to invoke an app associated with the media content provider, to access a website associated with the media content provider, and the like.

According to certain embodiments of the disclosure, an electronic device may include: a housing, a roller disposed in the housing, a first cover part configured to be detachable from the housing, a second cover part configured to be detachable from the housing, and a display including a first display area including a first end coupled with the first cover part, and a second display area including a second end coupled with the second cover part, wherein at least a portion of the first display area is configured to be wound around the roller while facing at least a portion of the second display area.

Apparatus, devices, systems, methods, and articles of manufacture are disclosed for physical keyboards with multi-display computing devices. An example computing device includes a first display, a second display, and a keyboard.

A display device includes the following: a flexible display body; and a support supporting the flexible display body, wherein the support has a hollow that enables intake/discharge of a gas. This can enhance the convenience of the flexible display body. An outer shape of the support is larger than an outer shape of the flexible display bod.
