The present disclosure is directed at automatically opening hinged components of computing devices. One of the computing device and a hinged component may include an electrical winding or coil while the other may include a magnet. When current is applied to the electrical winding (e.g., in a direction opposite of the North/South direction of the magnets' magnetic field), the electrical winding may generate a magnetic field opposite that repels the magnet's magnetic field. The magnetic repulsion may cause the hinged component to separate from the rest of the computing device, thereby opening the hinged component. When the current is removed from the electrical winding, the electrical winding may no longer generate a magnetic field, enabling the hinged component to be closed.

A hollow hinge includes a first hollow component, a second hollow component and a plurality of support assemblies. The first hollow component has a first surface and a second surface opposite to the first surface, and a plurality of concave portions are disposed on the second surface. The second hollow component is disposed on the second surface of the first hollow component and a plurality of receiving portions corresponding to the concave portions are disposed on the second hollow component. The support assemblies are respectively contained in the receiving portions and continuously butt against the first hollow component through a force. The hollow hinge avoids friction between components and strengthens support, thereby prolonging durability and improving assembly and production yield rate.

A display device and a driving method of the display device are provided. The display device includes a case, a first reel, a flexible display screen, and a retractable component. The first reel is located inside the case. The flexible display screen is wound on the first reel, and is retractable or expandable along a first direction. The retractable component includes a first retractable component including N retractable parts that are capable of sliding with respect to each other along the first direction, where N is a positive integer greater than or equal to 2. When the flexible display screen is expanded, the N retractable parts are expanded along the first direction and are arranged along a second direction, where the second direction intersects the first direction. When the flexible display screen is retracted, the N retractable parts are arranged in sequence along the second direction.

A master device is capable of communicating with an external device. The master device is capable of installing a slave device and allowing the slave device being detached from the master device. The slave device is capable of communicating with the master device after it is detached from the master device. The master device includes a main body and a bracket connected to the main body. The main body includes a front surface and a rear surface disposed opposite to the front surface. The front surface is provided with a receiving groove. The bracket is located at a side of the front surface. The bracket is capable of being rotated to a first position and a second position relative to the main body. The bracket is received in the receiving groove when in the first position, and is rotated out of the receiving groove when in the second position.

A hollow hinge includes a first hollow component, a second hollow component and a plurality of support assemblies. The first hollow component has a first surface and a second surface opposite to the first surface, and a plurality of concave portions are disposed on the second surface. The second hollow component is disposed on the second surface of the first hollow component and a plurality of receiving portions corresponding to the concave portions are disposed on the second hollow component. The support assemblies are respectively contained in the receiving portions and continuously butt against the first hollow component through a force. The hollow hinge avoids friction between components and strengthens support, thereby prolonging durability and improving assembly and production yield rate.

An electronic device includes a housing, a covering member that covers the housing, and an attachment part that detachably attaches the covering member to the housing. The attachment part includes a one-side attachment part and at least one other-side attachment part. The one-side attachment part includes a first projection of the covering member extending from a first member toward a second member, a first accommodation part of the housing that accommodates the first projection, and a first movement restriction part that restricts movement of the first projection. The other-side attachment part includes a protrusion of the covering member extending from a second member toward a third surface of the housing, a second projection extending from the protrusion in a direction away from the first member, a second accommodation part of the housing that accommodates the second projection, and a second movement restriction part that restricts movement of the second projection.

A highly convenient electronic device used while being worn on a body is provided. The electronic device is an arm-worn electronic device including a display panel, a power storage device, a circuit, and a sealing structure. The display panel displays an image with power supplied from the power storage device. The circuit includes an antenna and charges the power storage device wirelessly. Inside the sealing structure, the display panel, the power storage device, and the circuit are provided. The sealing structure includes a portion that transmits visible light. The sealing structure can be worn on an arm or is connected to a structure body that can be worn on an arm.

An under-screen support structure and a display device. The under-screen support structure is configured to support a rollable and slidable display screen (6) in the display device, and includes a sliding middle frame (1), a rotating shaft (2) and a support chain (3). The rotating shaft is mounted on the side of the sliding middle frame facing a rollable and slidable portion of the display screen, and the rotating shaft is transmittingly connected to the display screen by means of the support chain. The support chain includes a plurality of support strips, the extension direction of the support strips is parallel to the axis of the rotating shaft. The cross section of each support strip perpendicular to the axis of the rotating shaft is trapezoidal, and the size of the side facing away from the rotating shaft is greater than that of the side close to the rotating shaft.

Provided is a flexible display device including a back cover supporting a rear surface of a display panel, a bending member bent with a slow curvature and supporting a rear surface of the back cover, a sliding member supporting the bending member to be rotatable, mounted on the rear surface of the back cover, and rotating the bending member, while sliding up and down on the back cover, and a rotation support member having one end portion slidably and rotatably engaged with an end portion of the bending member and the other end portion rotatably engaged with the back cover.

A computing device includes a hinge rotatably coupling a first leaf including a touch display and a second leaf. A hinge angle sensor measures a hinge angle between the first leaf and the second leaf. An inertial measurement unit measures an orientation of one or both of the leaves. A first touch heat map is received from the touch display. Based on the touch heat map, hinge angle, and orientation, a posture probability is generated indicating a likelihood that the first touch display is in a candidate display posture, and an active probability is generated indicating a likelihood that the first touch display is an active display. One or more display characteristics of the first touch display are adjusted based on the posture probability and the active probability.
