Abstract: A flexible display screen includes: a flexible substrate (1); an OLED device layer (2) formed on the flexible substrate (1); an encapsulation layer(3), disposed on the OLED device layer(2) and encapsulating the OLED device layer (2); and an encapsulation protection layer (4) formed on the encapsulation layer (3). The embodiments of the present disclosure also provide a flexible display device and a manufacturing method of the flexible display screen.

Abstract: A self-powered wireless keyboard by modifying the structure of a traditional membrane keyboard having a volcanic crater structure. Not damaging the original membrane keyboard structure, a micro magnet core is installed inside a cylindrical protrusion block under the key cap as a mover of the induction power generation device, and an induction coil is wound in a key slot of the keyboard base as the stator of the induction power generation device. In this way, when each key is pressed, it will produce induction current. A layer of flexible solar cell can be laid on the upper surface of the key, which can generate electricity by collecting the light energy in the surrounding environment during the time of daily illumination.

Abstract: The present disclosure provides a linear motor including: a housing body with a containment space; a vibrator assembly suspended in the containment space by an elastic member for vibrating along a vibration direction; a stator assembly fixedly connected to the housing body and having a magnetic axis along the vibration direction; and two magnets located on both sides of the magnetic axis and spaced from the stator assembly, including a first magnet section and a second magnet section located on both sides of the first magnet section. A magnetic field strength of the first magnet section along the magnetic axis is greater than a magnetic field strength of the second magnet section along the magnetic axis. The configuration of the invention can effectively reduce the static attraction force of the magnetic circuit, and increase the overall rigidity of the linear motor.
