A double-screen rotary shaft structure includes two synchronous spiral channels disposed on the link shafts. Asynchronous assembly is slidably pivotally fitted on the two link shafts. Two bosses are disposed on the synchronous assembly and respectively inlaid in the spiral channels of the link shafts. Two connection members are respectively securely connected with the two link shafts. Two link assemblies are respectively pivotally fitted on the link shafts to synchronously move with the synchronous assembly. Two slide members are attached to lower sides of the connection members and formed with oblique slots. A guide slide connection member is disposed in each oblique slot and connected with the link assembly. The middle sections of two links are pivotally disposed on the connection members. Each link has a driving end pivotally connected with the link assembly and a driven end to drive the slide member.

In an example implementation according to aspects of the present disclosure, a computing device includes a first member with a first display surface, and a second member rotatably connected to the first member, the second member including a second display surface. The computing device includes a sensor and a processor to receive readings from the sensor. Based on the sensor readings, the processor is to select either a privacy mode or a sharing mode for the first display surface, and either the privacy mode or the sharing mode for the second display surface.

The present disclosure discloses a terminal device, including at least two folding portions, a rotational shaft, and a telescopic device, where each of the folding portions includes a housing and a display screen arranged on the housing, each housing is provided with the rotational shaft, two adjacent folding portions are connected to each other by the telescopic device, two ends of the telescopic device are respectively connected to the rotational shafts on the two adjacent folding portions, the terminal device has a folded state and an extended state, in the folded state, two adjacent folding portions are folded, and in the extended state, display screens of the two adjacent folding portions abut on each other and are coplanar.

Methods and devices for selectively presenting a user interface or “desktop” across two devices are provided. More particularly, a unified desktop is presented across a device and a computer system that comprise a unified system. The unified desktop acts as a single user interface that presents data and receives user interaction in a seamless environment that emulates a personal computing environment. To function within the personal computing environment, the unified desktop includes a process for docking and undocking the device with the computer system. The unified desktop presents a new user interface to allow access to functions of the unified desktop.

A display control method provided in embodiments of the present invention includes: obtaining, by a terminal, orientations and display statuses of a first screen and a second screen; determining, by the terminal, whether a trigger event used for adjusting the display statuses of the first screen and the second screen occurs; and when the trigger event occurs, displaying, by the terminal, adjusted display content on the first screen and the second screen based on the orientations and the display statuses of the first screen and the second screen. By obtaining an orientation and a display status of a terminal screen, when the trigger event occurs, the terminal can adjust the display status of the screen in a timely manner, so that a user can perform an interaction operation and interaction display between different screens.

A multi-processor mobile computing device includes a first processor connected to a first operating memory and a mobile display and powered by a portable power source integrated into the multi-processor mobile computing device, a second processor connected to a second operating memory and a display input-output port; the second processor is activated only when mobile device is connected to an external power source. The device includes a dual-function operating system, including a mobile operating system module operating on the first processor, the mobile operating system module having a first capability set and a desktop operating system module operating on the second processor; the desktop operating system module having a second capability set, wherein the second capability set differs from the first capability set.

A display apparatus includes a plurality of display panels, a mounting frame, and a central control circuit. The mounting frame includes a side ridge electrically coupled to each of the plurality of display panels. The central control circuit is arranged inside the side ridge. The plurality of display panels are arranged such that a side edge of each of the plurality of display panels is attached to the side ridge to thereby allow the each of the plurality of display panels to be flipped open or close along the side ridge. The central control circuit is electrically coupled to each of the plurality of display panels, and is configured to control a display state of each of the plurality of display panels upon receiving a control signal from a user.

A portable device having a display, the display including a main surface area, a first curved surface area extending from a first side of the main surface area, and a second curved surface area extending from a second side of the main surface area that is opposite the first side, a sensor configured to detect a state of the portable device, and a controller configured to control the display to display a user interface (UI) on one of the first curved surface and the second curved surface based on the state detected by the sensor.

A user terminal device and a displaying method thereof are provided. The user terminal device includes a display configured to display a first screen on a display which is divided by a folding line into a first area and a second area, the second area being larger than the first area with reference to a folding line and including an exposure area that is exposed while the display is folded along the folding line such that the first area faces the second area, a detector configured to detect, while the first screen is displayed, a first folding interaction of folding the display such that the first area faces the second area and a second folding interaction of folding the display such that a first cover corresponding to the first area faces a second cover corresponding to the second area, and a controller configured to, in response to detecting the first folding interaction, display a second screen related to the first screen on the exposure area, and in response to the second folding interaction being detected, display a third screen related to the first screen on the first area or the second area.

A mobile device cover displays notifications based on communication received by a host mobile device. The mobile device cover has multiple screens that can be unfolded. The multiple screens can operate as separate displays or at least two of the screens can form a composite display. One of the screens can provide a touch-sensitive keyboard.
