Abstract: The present disclosure provides a head-mounted device and relates to a field of smart device. The head-mounted device includes a first housing, two second housings and a tightness adjustment mechanism. The first housing defines a first receiving cavity and a second receiving cavity partitioned from each other along an up-down direction. The two second housings extend from either side of two opposite sides of the first housing respectively. Each of the two second housings defines a third receiving cavity. Each of the two third receiving cavities communicates with the first receiving cavity. A part of the first housing at a side of the second receiving cavity extends beyond the second housing. The tightness adjustment mechanism is received in the first receiving cavity. A motion of a pawl assembly is achieved, thus a tightness of the first and second head bands can be adjusted.

Abstract: Provided are a head-mounted device support assembly and a head-mounted device. The head-mounted device support assembly includes a telescopic arm, a tightness adjustment mechanism, and a control module. The telescopic arm has an initial length. The tightness adjustment mechanism is connected to the telescopic arm for use in adjusting the telescopic length of the telescopic arm. The control module is electrically connected to the tightness adjustment mechanism, and controls the tightness adjustment mechanism based on an adjustment signal to drive the telescopic arm to move, so that the telescopic length is extended from the initial length or retracted to a target length. The head-mounted device support assembly can improve the wearing convenience.

Abstract: A display assembly, an electronic device, and a method for assembling a display assembly are provided. The display assembly includes a flexible screen, a cover plate, and a capacitive fingerprint sensor film. The capacitive fingerprint sensor film is disposed between the cover plate and the flexible screen and covers a display surface of the flexible screen, to sense a fingerprint of a finger in contact with the cover plate.

Abstract: Disclosed are films, and methods of making such films, the films comprising a first polyethylene and a hydrocarbon resin, which can provide improved friction performance. The hydrocarbon resin may be incorporated in neat form or as a blend, for instance with a second polyethylene that may be the same as or different from the first polyethylene.

Abstract: A flexible display device may include a flexible display screen, a rotating shaft, a resetting mechanism, and a positioning mechanism. The flexible display screen is wound on the rotating shaft. The resetting mechanism may be connected to the rotating shaft. The resetting mechanism may be operable to drive the rotating shaft to rotate to unfold the flexible display screen. The positioning mechanism may be configured to position the unfolded flexible display screen; and the resetting mechanism may be further operable to drive the rotating shaft to rotate in an opposite direction such that the flexible display in the unfolded state may be wound on the rotating shaft.

Abstract: A mobile terminal includes a casing and a camera module. The camera module is received in the casing. The camera module includes a camera, a flash lamp, an electrical connector, and a flexible printed circuit (FPC). The FPC has a first end and a second end opposite to the first end. The camera is coupled to the first end of the FPC, and the electrical connector is coupled to the second end of the FPC. The flash lamp is disposed on the FPC. A camera module of the mobile terminal is also provided.

Abstract: An imaging module and an electronic device including the imaging module are provided. The imaging module includes a flexible printed circuit board and an imaging unit including two cameras arranged side by side and connected to the flexible printed circuit board. The flexible printed circuit board includes a projection portion projecting to a side edge of the imaging unit. The side edge extends along an arranging direction of the two cameras, and a width of the projection portion in the arranging direction is less than a length of the side edge.
