Abstract: A flexible display device is provided. A flexible display device according to one embodiment of the present invention comprises a body, a moving plate, a first pulley, a second pulley, a driving track and a flexible display. The flexible display is coupled to outer surfaces of the moving plate and the driving track, and the driving track forms a continuous track shape by itself or together with the moving plate. Therefore, provided is the flexible display device in which a constant tension can be maintained over the entire section of the driving track while the moving plate and the driving track support the flexible display, the occurrence of spring back in the flexible display can be minimized, and damage caused by unevenness of the flexible display, and the like, can be prevented.

Abstract: A flexible display device is disclosed. The flexible display device comprises a first body, a second body, a flexible display, a ball module, and rails. The ball module includes a case and a plurality of moving balls. The moving balls are inserted into circulation paths of the case and arranged to be movable along the circulation paths, and some of the moving balls are in contact with sliding grooves of the rails. The case may be fixed to the first body, and the rails may be fixed to the second body. When the second body moves in parallel to a first direction with respect to the first body, the moving balls in contact with the sliding grooves roll and move along the circulation paths, such that slippage and friction generated on the ball module can be reduced, and the second body can move smoothly.

Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body that moves in a first direction with respect to the first body, and a flexible display that varies according to the movement of the second body. Either one of the first body and the second body has coupled thereto a plurality of spherical rolling balls arranged in the first direction, and the other one has formed therein rolling grooves, in the form of concave grooves having a constant cross-section, in the first direction to allow the rolling balls to move in contact with same. In embodiments of the present invention, the movement of the second body is facilitated by a point contact of the rolling balls and the rolling grooves, and external exposure of an element for slidable movement of the second body may be minimized.
