The present disclosure provides a backplane, a frame structure and a display device. The backplane provided in the present disclosure is secured to a middle frame in a display panel to form a frame structure of the display panel, the backplane including: a bottom plate and a skirt connected to edges of the bottom plate, wherein at least part of the skirt is provided with a clamping member for securing the backplane to the middle frame, the clamping member is provided with a dismounting structure for disengaging the clamping member from the skirt under an external force so that the backplane is separated from the middle frame.

The present invention discloses a transmission device used for expanding monitors, comprising the body, and a combination of at least a first monitor, a second monitor and an actuation module that can be installed thereon. The actuation module can drive the second monitor to move reciprocally on a reference axis X; and the second monitor is provided with a drive module to drive the second monitor to move reciprocally on a reference axis Y perpendicular to the reference axis X, which jointly provide a mechanism, under which an expansion and combination of the screen of the first monitor and the screen of the second monitor (in the same planimetric position) and/or retraction thereof are enabled.

A holding structure according to an exemplary embodiment includes a rotation axis, a stand body, and a clicker. The stand body is rotatable about the rotation axis. When the stand body is rotated about the rotation axis, an upper end portion of the stand body contacts with the clicker. When the stand body is further rotated from a position at which the stand body and the clicker contacts with each other, the stand body rotates beyond the clicker. Thus, the stand body enters an opened state and holds an orientation of an apparatus. When the upper end portion of the stand body rotates beyond the clicker, the clicker is restored from a deformed state to an initial state, and a clicking sound occurs.

A hinged support apparatus for a portable electronic display device is disclosed that includes a mounting plate having a first and a second end portion. The mounting plate comprises an opening or mortise into which a magnetically susceptible material, such as a metallic plate, can be embedded. The disclosed hinged support apparatus also includes an elongated base having a proximal end and a distal end in which the proximal end is attached to the first end portion of the mounting plate. The elongated base can include at least one living hinge and, in some embodiments, one or more magnets. The magnets can be made of any ferromagnetic material. The disclosed hinged support apparatus can include an elastic band having a first end and a second end. The first end of the elastic band can be attached to the first end of the base, and the second end of the elastic band can be attached to the second end of the base.

A mobile phone holder is disclosed for mounting a mobile phone to the dashboard of a car. This mobile phone holder is integrated into the back of a mobile phone or is attached to the back surface of the mobile phone through adhesive pads, or suction cups, or is incorporated into accessories of mobile phones such as attachable card holding wallets, and etc. One embodiment of this mobile phone holder creates a closed loop around the air vent bars. Hence, shakes of the car will not cause sudden detachment and falling of the phone. In Addition, this mobile phone holder is portable and is carried by the mobile phone. Hence, the user can readily have it upon using a temporary car. Moreover, since this mobile phone holder is not permanently stayed in the car, it is not exposed to extreme temperatures and thus its wear and tear is lower than conventional phone holders. The loop that is formed by this apparatus can also be used for mounting a mobile phone to the handlebar of a shopping cart, the handlebar of a bike, safety belt of a car, a belt loop, belt of a user, strap of a bag, or other accessories of a user. This apparatus can also be used as a general purpose fastener for fastening two or more objects together, hanging objects from a bar. Such general purpose fastener can be used as a toy, strap of a watch, or bracelet as well.

A leg attachment structure for a keyboard instrument including leg main bodies that support a keyboard portion from both sides, the keyboard portion in which plural keys are arranged on a key bed, wherein the leg attachment structure has plates installed on upper surfaces of the leg main bodies, the plates and the leg main bodies are fixed by inserting rod-shaped portions formed on lower surfaces of the plates into hole portions provided in the leg main bodies, and the plates are formed to be larger than an area of the upper surfaces of the leg main bodies, and installed at positions eccentric to the inner side and the rear side of the keyboard portion with respect to the upper surfaces of the leg main bodies.

The present disclosure is directed at automatically opening hinged components of computing devices. One of the computing devices 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 fastening device includes a self-adhesive part having a self-adhesive surface and a connecting surface which is situated on the opposite side from the self-adhesive surface. A flexible strip extends from the connecting surface of the self-adhesive part. The flexible strip is joined to the self-adhesive part by means of a connecting element disposed in a region on the connecting surface. This region faces a central region of the self-adhesive surface. Thus, a traction force exerted on the flexible strip is distributed substantially uniformly over the self-adhesive surface.

The present disclosure discloses a flexible display auxiliary device and a foldable mobile terminal. The flexible display auxiliary device includes a platform, a first stage, a second stage, a sliding mechanism and an enabling mechanism. The first stage is used for fixing the first end of the flexible display screen, the second stage is used for fixing the second end of the flexible display screen opposite to the first end. The second stage is fixedly arranged on the sliding mechanism, the sliding mechanism is arranged on the platform, the enabling mechanism is connected to the sliding mechanism to control the sliding mechanism to move on the platform so as to change the relative distance between the first stage and the second stage and change the tension on the flexible display screen. In the above manner, the present disclosure enables the flexible display to always be in a flat state.

An electronic display includes a screen for displaying digital content, an electronic operating circuit for operating the screen, a support supporting the screen and the operating circuit, and a stand. The support has a recess and includes a positioner for positioning the support in a standing position, in which the support stands on a surface, and a hung position, in which the support is hung on a surface. The stand has an engagement part engageable with the positioner for standing the support in the standing position. The stand includes a first electrical connector for connecting the operating circuit to a power source. The electronic display also includes a second electrical connector for connecting the operating circuit to a power source. The second electrical connector includes an electrical connecting unit for use in the hung position, with the positioner engaging an engaging element on a surface from which the support is hung.
