Abstract: Embodiments of a method for synthesizing water-soluble metal oxide nanoparticles are disclosed. In one embodiment, the method includes heating a first reaction mixture at a predetermined temperature for a predetermined time duration with continuous stirring to obtain a second reaction mixture that comprises water-soluble metal oxide nanoparticles of a first size. The first reaction mixture includes a reactant and a polyol. The method further includes adding a first predetermined amount of the reactant to the second reaction mixture to obtain a third reaction mixture. The method further includes heating the third reaction mixture at the predetermined temperature for the predetermined time duration with continuous stirring to obtain a fourth reaction mixture comprising water-soluble metal oxide nanoparticles of a second size. The reactant is Fe(acac)3 and the polyol is diethylene glycol (DEG) for synthesizing water-soluble iron oxide nanoparticles.

Abstract: The present application provides a back plate structure and a flexible display device. The back plate structure includes: a first back plate, a second back plate and a flexible shaft. The first back plate and the second back plate are connected by the flexible shaft. The flexible shaft includes an arch component and at least one end component. The arch component includes a concave surface and a convex surface corresponding to the concave surface, and the concave surface faces a bending direction of the flexible display device. Each end component includes at least one foldable structure, and each foldable structure includes two planes parallel to a bending axis of the flexible display device. Each end component is located at an end of the arch component and obscures a space formed by the arch component.

Abstract: A screen supporting device includes: a drive component and a supporting component rotationally connected to the drive component. The drive component comprises a rotating shaft and a connecting rod that rotationally connected to the rotating shaft. The drive component and the supporting component are disposed in a non-display surface of the flexible display screen. The connecting rod is fixedly connected to the supporting component. Through the rotating connection between the rotating shaft and the connecting rod, the supporting component and the drive component relatively rotate and move away from each other to fold or expand the flexible display screen.
