Abstract
An outward-folding display device includes two flat casings adapted to be connected to a flexible display, and two hinge units connected between the casings such that the casings are convertible between unfolded and folded positions. Each of the hinge units includes two rotatable drive shafts, and two compensation subunits each including a rotating plate that is co-rotatably connected to a respective one of the drive shafts, and a driven plate that is slidable relative to the rotating plate and that is connected to a respective one of the casings, such that during conversion of the casings, the driven plate and the respective one of the casings slide relative to the rotating plate to prevent the flexible display from being stretched and damaged.
