Abstract: A reel assembly, located in a supporting assembly, comprises a reel, a first end cover, a second end cover, a spring and a shaft. The shaft is fixed to the support assembly. The spring is sleeved on the shaft. The reel is sleeved surrounding the spring. The first end cover is sleeved on one end of the shaft and fixedly coupled to one end of the reel. The second end cover is sleeved to the other end of the shaft and fixedly coupled to the shaft. The second end cover is rotatably coupled to the other end of the reel. Two ends of the spring are respectively fixed to the first end cover and the second end cover. The reel is used for winding the flexible screen. Expanding of the flexible screen drives the reel to rotate the flexible screen. A display device and a mobile terminal are also disclosed.

Abstract: The present disclosure provides a display device comprising a housing having electronic components and a supporting assembly for supporting a display screen. The supporting assembly comprises a foundation support and a connecting piece. A circuit board electrically coupled to the display screen is disposed inside of the foundation support. One side of the foundation support is provided with a conductive sheet electrically coupled to the circuit board. The connecting piece comprises an abutting piece electrically coupled to the electronic components and a supporting piece extending from the abutting piece. The connecting piece is fixed to the housing. The supporting piece is electrically coupled to the conductive sheet through thimbles. The present disclosure also provides a mobile terminal.

Abstract: An electronic device is provided. The electronic device includes a flexible body and a strap. The flexible body includes a flexible display screen, and two ends of the strap connect to two ends of the flexible body, respectively. When the flexible body is in a flat state, the strap attaches to a back surface of the flexible body opposite to the flexible display screen. When the flexible body is in a curved state, the strap and the flexible body together form an annular structure.

Abstract: A supporting assembly for supporting a flexible screen, includes a first main body, a second main body, and a rod assembly. The rod assembly includes a first fixed end and a second moving end respectively located at a pair of diagonal positions of the rod assembly, and a second fixed end and a first moving end respectively located at another pair of diagonal positions. The first fixed end is rotatably coupled to the first main body. The second fixed end is rotatably coupled to the second main body. The first moving end is slidably coupled to the first main body. The second moving end is slidably coupled to the second main body. A rotation limiting structure is located at a rotational connecting position between the first fixed end and the first main body, so, the first main body is positioned at different positions relative to the second main body.

Abstract: A supporting assembly for supporting a flexible screen and a display device is provided. The supporting assembly includes a first main body having a first limiting part and first guiding rod, a second main body having a second limiting part and second guiding rod, and a rod assembly. The rod assembly includes a first fixed end, a second fixed end, a second moving end, and a first moving end.
