Apparatus, systems, articles of manufacture, and methods are disclosed for physical keyboards with multi-display computing devices. An example keyboard includes a plurality of keys and a translucent backplate having a first side and a second side. The example keyboard also includes a coating between the first side of the backplate and the plurality of keys, the coating to pass light to illuminate the plurality of keys, and the coating to obscure the plurality keys when viewed from the second side of the backplate.

In embodiments, an electronic device includes: a foldable housing that includes a hinge, a first housing connected to the hinge, the first housing having a first surface facing a first direction and a second surface facing a second direction opposite the first direction, and a second housing connected to the hinge and configured to be foldable with the first housing around the hinge, the second housing having a third surface facing a third direction and a fourth surface facing a fourth direction opposite the third direction. The first surface faces the third surface in a folded state, and the third direction is equal to the first direction in an unfolded state. The electronic device further includes a first display extending from the first surface to the third surface to define the first and third surfaces, a second display viewable through at least a part of the second or fourth surface, at least one sensor, a processor disposed in the first or second housing structure, and a memory operatively connected to the processor. The memory stores instructions which, when executed, cause the processor to control the electronic device to display a plurality of applications on the first display in the unfolded state, to select at least one of the plurality of applications, based on an input or priorities of the plurality of applications, based on the at least one sensor detecting that the foldable housing is changed from the unfolded state to the folded state, and to display the selected application on the second display.

In some examples, a system includes a primary side with a charger and a first battery and a secondary side with a second battery. The charger on the primary side can charge both the first battery and the second battery. A hinge resistance is between the primary side and the secondary side. The primary side includes a feedback controlled active device in a current path of the first battery that compensates for the hinge resistance, for connector resistances, or for battery impedances in a current path of the second battery.

An electronic device includes a transparent cover and a flexible display screen. The transparent cover has a transparent cover having a fixed shape and including a plate-shape flat surface and a sidewall, the sidewall being formed by extending an edge of the flat surface away from the flat surface, the sidewall having a curved structure, and the sidewall and the flat surface forming an inverted structure; and a flexible display screen being fitted to an inner surface of the transparent cover, a display output surface of the flexible display screen facing the transparent cover, the flexible display screen including a non-deformable portion and a deformable portion, the non-deformable portion being fitted to the flat surface, and the deformable portion being fitted to the sidewall.

A dual-screen user device and methods for revealing a combination of selected desktops and applications on single and dual screens are disclosed. Desktops and applications can be shifted between screens by user gestures, and/or moved off of the screens and therefore hidden. Hidden desktops and screens can be re-displayed by other gestures. The desktops and applications are arranged in a window stack that represents a logical order of the desktops and applications providing a user with an intuitive ability to manage multiple applications/desktops running simultaneously. One embodiment provides an annunciator window extending across both screens in a dual screen configuration. The annunciator window provides alerts, notifications, and statuses of the device in an increased area thereby enhancing viewability of the information in the window. The annunciator window can be expanded over a selected screen to view full contents of the window without having to minimize or close running applications.

Embodiments provide for a handheld device with a unified desktop for integrating the functionality of the handheld device with a larger computer system. When connected to a peripheral display and/or a display of the larger computer system, the handheld device provides a unified desktop displayed across the screen(s) of the handheld device and the peripheral display. The unified desktop unifies the functionality provided by the larger computer system and the handheld functionality, e.g., communication applications (e.g., phone, SMS, MMS). A user can seamlessly interact with applications, e.g., open, move, close, receive notifications, on the unified desktop whether the applications are displayed on the screens of the handheld device, or the peripheral display of the larger computer system.

Provided is a display device including: left and right displays that are spaced apart from each other; left and right lens groups respectively located at the rear of the left display and the rear of the right display; left and right display housings configured to surround the left and right displays and the left and right lens groups; a main frame provided between the left and right display housings; a connection structure capable of adjusting an angle between the main frame and a connector electrically connected to an external electronic device; and electronic components provided inside the main frame.

An electronic device is provided in the present disclosure. The electronic device has an imaging region and an auxiliary display region connected with the imaging region. The electronic device includes a main display screen and an auxiliary display screen disposed opposite to the main display screen, and the auxiliary display screen is disposed corresponding to the auxiliary display region.

There is disclosed in one example, an encasement for a mobile computer, including: an external casing in a clamshell form factor, the external casing including a base, a secondary display chassis hingedly connected to the base at a secondary hinge, and a primary display chassis hingedly connected to the secondary display chassis at a primary hinge disposed at a removed edge of the secondary display chassis from the secondary hinge, the primary display chassis to substantially overlay the secondary display chassis and the base when the primary hinge is in a closed position; and pivot means disposed to substantially bias the secondary hinge against movement from a selected position in at least one direction in the absence of an electrical input.

A rotation shaft assembly includes a pivot assembly including a common rotation shaft, and a lock member, a first connection member, a second connection member, and a third connection member disposed at the common rotation shaft. The first connection member, the second connection member, and the third connection member are configured to be connected to a first member, a second member, and a third member, respectively. The lock member has a locked state that enables the first connection member and the second connection member to rotate synchronously, and an unlocked state that enables the first connection member and the second connection member to rotate independently with respect to each other.
